1 Overview of XP Performance Advisor The HP StorageWorks XP Performance Advisor Software (XP Performance Advisor) is a web-based application that collects, monitors, and displays the performance of your XP disk arrays. It includes performance data for individual resources such as: Logical Device (LDEV) Client-Host Interface Processor (CHIP) or Channel Adapter (CHA) Array Control Processor (ACP) or Disk Adapter (DKA) Disk Controller (DKC) XP Performance Advisor resources The following resources constitute an XP Performance Advisor setup: XP Performance Advisor: It is a web-based application tha t monitors the performance of XP disk arrays, and provides a visual representation of the collated data. It resides on a centralized server called the management station, manages data collection, and provides performance data of your XP disk arrays for your analysis. You can use the data to analyze and interpret the behavior of your XP disk arrays, and also forecast the utilization of a few components, such as XP Thin Provisioning belonging to the XP disk arrays. XP Performance Advisor host agents: XP Performance Advisor interacts with resources called host agents that collect data from the XP disk arrays. They are operating system specific, and reside on systems called the hosts. In a traditional setup, the host agents form the point of contact for the XP Performance Advisor to receive data from the XP disk arrays. However, XP Performance Advisor can also directly interact with the XP disk arrays. The host agents help XP Performance Advisor discover hosts and also communicate commands and data, back and forth between the hosts and the management station. Web clients: XP Performance Advisor can be locally accessed on the management station, or remotely accessed from a client system. The web browser that allows the access to XP Performance Advisor is called the web client. Internet Explorer (IE) is the only supported web client for XP Performance Advisor. Command Line User Interface (CLUI): In addition to its GUI, XP Performance Advisor also provides a command-line utility called the CLUI to monitor real-time performance of XP disk arrays. The CLUI allows you to monitor performance, set alarms, and configure host information using commands and scripts. You can execute commands in the CLUI and view the same data that is displayed on the GUI. The CLUI utility is operating system specific, and can be installed locally on the management station, or remotely on a client system. Figure 1 on page 10 shows the XP Performance Advisor setup collecting data from two XP disk arrays through a host agent. The CLUI utility is installed on the remote client system that is connected to the management station, thereby enabling it to access the XP Performance Advisor.

For more information, see Management station prerequisites on page 23. Designing the infrastructure The following procedure helps you to estimate the number of management stations, hosts, and XP disk arrays required: HP StorageWorks XP Performance Advisor Software Installation Guide 19

1. Collecting information about the XP disk arrays you will be monitoring on page 20 2. Determining the management station and host requirements on page 20 3. Preparing your XP disk arrays and determining their data collection schedules on page 22 Collecting information about the XP disk arrays you will be monitoring 1. Determine the number of logical devices (LDEVs) for each of the XP disk arrays. 2. Determine how frequently you want to access data from the XP disk arrays. IMPORTANT: The rate of data collection can affect the loads seen by the management station and the XP disk arrays. XP Performance Advisor provides the following types of data collection: Configuration data collection: The frequency of configuration data collection depends on how often you change the configuration of an XP Disk Array. For example, if you add a LUN to an XP Disk Array every week, you may collect configuration data at least once a week to see the changes reflected in your XP Performance Advisor database. Performance data collection: For troubleshooting XP Disk Array performance issues, HP recommends a collection frequency of 1 to 3 minutes. IMPORTANT: Frequent collection increases the load on your management station and the XP disk arrays. For real-time troubleshooting, HP recommends using XPWatch, which is one of the utilities included in XP Performance Advisor to collect real-time performance data for troubleshooting purpose. For general monitoring and forecasting resource utilization, HP recommends a collection frequency of 5-30 minutes. Determining the management station and host requirements Follow these steps to determine your management station and host setup requirements: 1. Check the supported configuration for management station and host agent. For more information, see Verifying the supported configurations for XP Performance Advisor on page 23 and Verifying the supported configurations for XP Performance Advisor host agents on page 33. 20 Understanding the XP Performance Advisor installation prerequisites

2. Increase the management and host agent configuration based on the number of LDEVs you require and collection frequencies you want to set. The following items can help you estimate the configuration you will need. To estimate the number of XP disk arrays that can be supported with one management server and host agent: Table 3 Large XP disk array configurations Data Collection Frequency Management Station Host # Arrays Managed # LDEVs Components 1 1 1 64K 45 minutes LDEVs 1 1 1 32K 30 minutes LDEVs 1 1-3 > 1 (2 to 3) 32K (aggregated) 10-15 minutes LDEVs For DKC and Ports, you must set the data collection frequency to 10 minutes. To estimate management server drive space required for the XP Performance Advisor database: HP recommends that there be at least a week's historic data available when you are forecasting using charts or alarms. Determining disk space requirements: Use the following formula to determine the disk space requirements for XP Performance Advisor on a daily basis. The factors that influence the output are the number of: XP disk arrays, LDEVs, ports, and DKC resources. Also, the performance data collection and frequency influence the output. Free_Space (MB/day for one array) = [(SECONDS_PER_DAY / Ldev_Collection_frequency) * LDEVs * Ldev_Space ] + [(SECONDS_PER_DAY / Port_Collection_ frequency) * PORTs * Port_Space] + [(SECONDS_PER_DAY/ Dkc_Collection_ frequency) * Dkc_Space] where: Free_Space (MB/day) = Total free disk space (in MB) required for a day LDEVs = Total number of LDEVs of an array (includes journal volumes, pool volumes, external volumes, and so on) PORTs = Total number of ports for an XP Disk Array Ldev_Collection_frequency = Collection frequency for LDEVs (in seconds) Port_Collection_frequency = Collection frequency for ports (in seconds) Dkc_Collection_ frequency = Collection frequency for dkc (in seconds) Ldev_Space ( per Ldev) = 0.0002 MB Port_Space (per port) = 0.00008 MB Dkc_Space (per collection) = 0.0002 MB SECONDS_PER_DAY = 86400 The consolidated free space that is available for XP Performance Advisor is the total sum of the free space available on all the XP disk arrays monitored by XP Performance Advisor. Example 1. Determining the disk space requirements for XP Performance Advisor Consider that XP disk arrays 10055 and 10090 are monitored by the XP Performance Advisor management station. HP StorageWorks XP Performance Advisor Software Installation Guide 21

10055 XP Disk Array details: LDEVs = 1703 PORTs = 96 Dkc_Collection_frequency = 300 seconds (5 * 60) Ldev_Collection_frequency = 600 seconds (10 * 60) Port_Collection_frequency = 600 seconds (10 * 60) Free_Space on 10055 array = [(86400/600) *1703 * 0.0002] + [(86400/ 600) * 96 * 0.00008] + [(86400/300) * 0.0002] = 49.04 + 1.1 + 0.05 = 50.19 MB 10090 XP Disk Array details: LDEVs = 2554 PORTs = 32 Dkc_Collection_ frequency = 300 seconds (5 * 60) Ldev_Collection_ frequency = 900 seconds (15 * 60) Port_Collection_ frequency = 600 seconds (10 * 60) Free_Space on 10090 array = [(86400/900) *2554 * 0.0002] + [(86400/ 600 ) * 32 * 0.00008 ]+[(86400/300) * 0.0002] = 49.03 + 0.36 + 0.05 = 49.45 MB Consolidated free space that is available for XP Performance Advisor (MB/day) = 99.64 MB (50.19 MB + 49.45 MB) Preparing your XP disk arrays and determining their data collection schedules To achieve the optimal CHIP port (MP) performance utilization, during performance data collection, HP recommends using two command devices that connect through two different ports (two different MPs). For more information, see Creating and presenting command devices to hosts on page 35. To collect performance data of RAID groups (RAID groups, snapshot, THP, External RAID groups) and journal components, HP recommends using a command device and port that are not shared with other critical applications. This is because collecting performance data for RAID groups is an intensive operation. You can create another schedule to collect performance data for the remaining set of components, through a different command device and port. Stagger schedule: If the data collection frequency is set to 15 minutes, performance data collection occurs at every quarter hour, irrespective of when the schedule is created. For example, if the schedule is created at 10:12 a.m., the first collection occurs immediately and the next collection occurs at the quarter of the hour, which is 10:15 a.m. Subsequent collections occur at 10:30 a.m., 10:45 a.m., and so on. If you select the Stagger Schedule check box, performance data collection occurs every 15 minutes from the time the schedule is created. For example, if the schedule is created at 10:12 a.m., the first collection occurs immediately and the next collection is 15 minutes later, which is at 10:27 a.m., and subsequent collections every 15 minutes after that. The Stagger schedule ensures that the load on Performance Advisor at any point in time is balanced because data collection occurs for all the XP disk arrays not every 15 minutes of the hour, but at varied points of time in the day.

Ensure that the check box for Internet Protocol Version 6 (TCP/IPv6) is selected under the Networking tab. Either IPv6 or IPv4 is used for communication between the management station and its host, based on whether you select IPv6 or IPv4 while installing the host agent. Determining the authentication type for XP Performance Advisor You must select an authentication type based on the current setup of your management station. The credentials that you use to log in to XP Performance Advisor change based on the type of authentication method you select. The following types of authentication are supported by XP Performance Advisor: Performance Advisor Native Authentication Windows System Authentication Windows Domain based Authentication LDAP Authentication RADIUS Server Authentication NOTE: To implement the Windows System Authentication or Windows Domain based Authentication on your management station, ensure that your management station is part of a domain. To implement the Windows Domain, LDAP, or RADIUS authentication type, you must complete the prerequisites that allow XP Performance Advisor to work with the selected authentication server to authenticate and authorize users. For more information, see Windows Domain based Authentication on page 27, LDAP Authentication on page 27, and RADIUS Authentication on page 27. Performance Advisor Native Authentication The Performance Advisor Native Authentication is the simplest method to manage user accounts and is required if you want XP Performance Advisor to maintain its own set of user credentials. During installation, if the XP Performance Advisor installer detects that your management station is not configured to be part of a Windows domain or able to communicate with an LDAP, or RADIUS server, Performance Advisor Native Authentication is implemented. There are no prerequisites associated with the Performance Advisor Native Authentication type. Windows System Authentication The Windows System Authentication is required in the following case: 1. Your management station belongs to a Windows domain. 2. Your XP Performance Advisor users are a combination of local system users and group of users belonging to the same, or different domains. OR Your XP Performance Advisor users are a combination of local system users or group of users belonging to the same, or different domains. There are no prerequisites associated with the Windows System Authentication. 26 Understanding the XP Performance Advisor installation prerequisites

Windows Domain based Authentication The Windows Domain based Authentication is required if you want to implement the domain-based authentication for administrators and user domain groups residing on the same or different domains. Only users belonging to the domain groups are given privileges to log in to XP Performance Advisor. By default, XP Performance Advisor refers to these groups as HP Storage Admins and HP Storage Users. To implement Windows Domain based Authentication, your domain or site administrator must create the two default domain groups, or the domain groups of choice on the domain controller. LDAP Authentication The LDAP Authentication is required if you want to implement the Lightweight Directory Access Protocol (LDAP) for centralized authentication, where the LDAP server authenticates and authorizes XP Performance Advisor users. The following LDAP server implementations and authentication mechanism are supported by XP Performance Advisor v4.5 and later versions: Supported LDAP server implementations Supported LDAP authentication mechanism OpenLDAP Microsoft Active Directory SIMPLE (clear-text password) mechanism To implement the LDAP Authentication, complete the following prerequisites: Install LDAP v3 (RFC 4510) on a server with an established XP Performance Advisor connection. Create the StorageAdmins and StorageUsers groups on the LDAP server, and add members to these groups. For the SIMPLE (clear-text password) mechanism and a secure connection, enable SSL on both the LDAP server and XP Performance Advisor management station. IMPORTANT: Note the LDAP Distinguished Names (DN)s for the StorageAdmins and StorageUsers groups. An LDAP group used with XP Performance Advisor must have the DNs of the group members available in an attribute of the group. Note the UserBaseDN and GroupBaseDN required for XP Performance Advisor to allow authentication and authorization of users. UserBaseDN is the location in the LDAP tree that contains all the user entries. XP Performance Advisor uses UserBaseDN to search user entries in the LDAP directory when authenticating users. GroupBaseDN is the location in the LDAP tree that contains all the group entries. XP Performance Advisor uses GroupBaseDN to search group entries in the LDAP directory when authorizing users. RADIUS Authentication RADIUS Authentication is required if you want to implement RADIUS protocol for centralized authentication, where the RADIUS server authenticates and authorizes XP Performance Advisor users. The following RADIUS server implementation and authentication mechanisms are supported by XP Performance Advisor v4.5 and later versions: HP StorageWorks XP Performance Advisor Software Installation Guide 27

RADIUS server implementation RADIUS authentication mechanisms Microsoft Active Directory with Internet Authentication Service (IAS) for Windows platform PAP: Password Authentication Protocol CHAP: Challenge Handshake Authentication Protocol To implement RADIUS Authentication, your system administrator must add a RADIUS Vendor-Specific Attribute (VSA) to the user profile on the RADIUS server. The VSA is required for authorizing XP Performance Advisor and it must have an attribute type of 1, and a vendor ID of 11 that is assigned to Hewlett-Packard by IANA. Further, the VSA can have one or both of the following attribute values, depending on the role assigned to the user profile. In the following examples, a VSA attribute type and value is assigned to an XP Performance Advisor administrator and user: Example 2. VSA added to User_1 profile in the XP PA administrators group: Vendor_ID=11 SubAttributeType=1 Attribute Value= XPPA: role=administrator (For XP Performance Advisor administrators: XPPA: role=administrator) Example 3. VSA added to User_2 profile in the XP PA users group: Vendor_ID=11 SubAttributeType=1 Attribute Value= XPPA: role=user (For XP Performance Advisor users: XPPA: role=user) For more information on implementing the above-mentioned types of authentication, see Implementing the authentication method on page 50. Creating 1 GB of free disk space At least 1 GB of free disk space in your management station s TEMP folder is required for a Complete installation of XP Performance Advisor.

Restart the XP Performance Advisor host agent services. For example, <install directory>:\program Files\Hewlett-Packard\xppa\ hostagent\sbin> xppa restart 5. On the management station, launch XP Performance Advisor and click Array View on the left pane. 6. In the Array View screen, select the host agent record in the Host Information table, and click Request Info. 7. After the Status column shows Received for the selected host agent record, click the Configuration Collection or Performance Collection tab. All the command devices on which the GUID is created are appended with GUID. The XP Performance Advisor configuration and performance data collection through the command device file names labeled with (GUID) string uses \\?\Volume {GUID}. 32 Understanding the XP Performance Advisor installation prerequisites

NOTE: To ensure accurate performance data collection: The command device on which the GUID is created must always be mounted. When you create a GUID, you must request updated host agent information under the Host Information tab. If you delete a GUID partition and recreate it, you must request the updated host information under the Host Information tab. If GUID creation is successful and the command device is corrupted, the XP Performance Advisor configuration and performance data collection might fail.

. The Ready to Complete dialog box displays your current selection. 8. Click Finish. If you want to modify the current selection, click Back. The new hard disk is added to the Hardware list. You can proceed with the host agent installation. Verifying host connectivity to a command device Command devices must be created and presented to your host to establish connectivity between your host agent and the XP Disk Array before you begin the host agent installation. If a command device is not created and presented to the host, the XP RAID Manager Library version will not be displayed when you request an host update from XP Performance Advisor. Use XPInfo to verify if a command device is presented to your XP Performance Advisor host. IMPORTANT: XPInfo is available in the Tools folder on XP Performance Advisor Installation disk 2, and must be executed separately. HP does not recommend connecting a command device through multiple paths. The following commands can be used before and after the installation of the Windows and UNIX host agents to verify if the command devices are connected: To verify if a command device is presented to a Windows host: In the command prompt window of your host, type xpinfo.exe - i find -CM. Figure 5 Sample xpinfo -i output for Windows host agent. Where, CM in the Type indicates a command device. You can also test the host connectivity to a command device during the Windows host agent installation. For more information, see Installing the XP Performance Advisor Windows host agents on page 73. To verify if a command device is presented to a UNIX host: In the command prompt window of your host, type xpinfo -z. Figure 6 Sample xpinfo -z output for UNIX host agent Configuring SSL settings for the XP Performance Advisor host agents You can generate unsigned SSL certificates on the server and add them to the JRE's trusted list of certificates to enable SSL on a XP Performance Advisor host agent. The advantage with this method HP StorageWorks XP Performance Advisor Software Installation Guide 39

is that it does not need a Certificate Authority (CA) signed certificate. The client takes the public key from the server and stores it in a keystore, and then places the keystore in the JRE s trusted site list. This enables the XP Performance Advisor host agent to establish a SSL connection to secure the data transfer. To enable SSL on a XP Performance Advisor host agent: 1. Navigate to the bin folder in the JRE location defined by your JAVA_HOME variable. 2. Generate keystore on the Tomcat server: <%JAVA_HOME%>\bin>keytool -genkey -alias tomcat -keyalg RSA -keystore <%HPSS_HOME>\hpss\pa\tomcat\conf\keystore 3. When prompted, provide the password as changeit. 4. When prompted for the first name and last name, enter the fully-qualified domain name of your management station. For example, abc.domain.company.com. 5. For the rest of the fields, enter appropriate values in the order mentioned: Division, Company (your company name), City, State, and Country. NOTE: The Country field can accept only two characters. 6. Enable https for your XP Performance Advisor management station by editing the server.xml file in the <PA_Install folder>\hpss\pa\tomcat\conf folder: <Connector port="443" protocol="http/1.1" SSLEnabled="true" maxthreads="150" scheme="https" secure="true" keystorefile="${catalina.home}/conf/keystore" keystorepass="changeit" clientauth="false" sslprotocol="tls" /> Comment out the following lines in the server.xml file, as shown below: <!--- <Connector port="80" protocol="http/1.1" connectiontimeout="20000" redirectport="443" /> ---> The keystore location is provided by the Tomcat server. 7. Start the Tomcat server in the SSL mode: https://[server name].[domain name]/pa or https://[ip address]/pa 8. On the XP Performance Advisor host agent, download the InstallCert program from the following location: http://blogs.sun.com/andreas/resource/installcert.java. NOTE: JavaC is required to compile the InstallCert program on the host agent server. When you compile the program, ensure that it is named as InstallCert. 40 Understanding the XP Performance Advisor installation prerequisites

9. To retrieve the public key from the XP Performance Advisor management station and create a keystore, type: <%JAVA_HOME%>\bin\javaC InstallCert <Fully_Qualified_Name_for_Management_Station>:443 Example of a DNS, abc.domain.company.net.

For more information, see Selecting complete or custom installation method on page 58. After installing XP Performance Advisor for the above-mentioned authentication type, you can login as an administrator, create user accounts, and grant them privileges (administrator or user privileges) to perform various tasks using XP Performance Advisor. You can also login as a storageadmin, who is an administrator user of CV XP and has the same privileges as that of the administrator user of XP Performance Advisor. For more information, see Configuring XP Performance Advisor related settings on page 64. Windows System Authentication In this authentication method, the XP Performance Advisor installer checks for the following groups on your local system and creates them if they do not exist: HP Storage Admin HP Storage Users They are provided the same privileges that XP Performance Advisor Administrators and Users own. Apart from viewing the data displayed on the XP Performance Advisor screens, HP Storage Administrators can also create and schedule new reports, modify existing reports, generate reports, and manage database configuration. After installing XP Performance Advisor for the above-mentioned authentication type and if you have administrator privileges on your local system, you can add yourself and other local users, domain users or groups to the HP Storage Admin and the HP Storage Users groups appropriately. For more information, see Configuring XP Performance Advisor related settings on page 64. Click Next to proceed. The Choose Setup Type installation window appears. For more information on the next set of steps, see Selecting complete or custom installation method on page 58. Windows Domain based Authentication In this authentication method, enter the Domain Name and Group Name for the administrators and users. It is mandatory that you provide a domain name and group name each for both the administrators and users. Only users belonging to these domain groups (global groups) are given the administrator and user privileges, and are authorized to log in to XP Performance Advisor. By default, the XP Performance Advisor installer displays HP Storage Admins and HP Storage Users as the domain groups. You can retain these names or provide group names of your choice (the groups with the names that you provide must exist on the domain controller). NOTE: Ensure that the domain or site administrator has created the two default domain groups, HP Storage Admins and HP Storage Users or the domain groups of your choice on the domain controller.

The default port # for LDAP with SSL is 636. The default port # for LDAP without SSL is 389. You can also specify a port# of your choice. In case, there is already an LDAP server configured on another port, XP Performance Advisor uses this LDAP server for authentication and authorization purposes. Server Type list OpenLDAP The type of the LDAP server implementation: Microsoft Active Directory HP StorageWorks XP Performance Advisor Software Installation Guide 53

Screen elements Use SSL when communicating with the LDAP server check box Use anonymous login when connecting to the LDAP server check box User DN, Password, and Confirm Password text boxes Description Select this check box to use SSL when communicating with the LDAP server. Ensure that SSL is also enabled on the LDAP server before selecting this check box. If not selected, it might result in authentication and authorization failures for XP Performance Advisor users. By default, XP Performance Advisor supports the simple (clear-text password) authentication mechanism with the LDAP server, wherein SSL is not enabled for the LDAP server. To secure communications between XP Performance Advisor and the LDAP server, enable SSL on the LDAP server. Select this check-box if you want XP Performance Advisor to connect to the LDAP server as anonymous for the purpose of user authentication. If this mode is chosen, the User's DN, Password, and Confirm Password text boxes are disabled. An anonymous connection is established when logging into XP Performance Advisor. The LDAP directory is searched (anonymously) to determine the user's DN, and then authentication is attempted using the user's DN and the supplied password. Specify the details of a user account that has read and search permissions on the LDAP directory. This account will be used to search the LDAP directory for user entries and lookup the user group membership information. IMPORTANT: Ensure that the DNs provided are correct and do not have any spelling errors in their names. If the DNs provided are incorrect, the installation will still complete. However, later you might not be able to connect to the LDAP server due to the wrong DN. 2. Click Next to proceed.

For more information, see Using XP Performance Advisor on page 97. 96 Upgrading XP Performance Advisor host agents

8 Using XP Performance Advisor After installing the XP Performance Advisor and host agents, you can start collecting configuration and performance data for your XP disk arrays. You can initiate configuration data collection for only one XP Disk Array at a time, and select only one command device through which you can collect data for the XP Disk Array. For frequently monitoring the XP Disk Array resources and collecting performance data, you can create two performance data collection schedules for an XP Disk Array. The resources that are not selected as part of the first schedule are automatically added to the second schedule that you create. You can set different collection frequencies for resources belonging to the DKC, Ports, and RAID Groups resource types, and also enable the schedules for automatic updates. The collection frequency set for a RAID Group in a schedule is applicable for any resource of the XP Continuous Access Journal, Snapshot, RAID Group, XP Thin Provisioning, and External RAID Group type. This is applicable only if they are selected for performance data collection. Collecting configuration data on page 98 Collecting performance data on page 100 IMPORTANT: Ensure that the date and time on the management station and hosts are synchronized with the local time zone to receive accurate configuration data. If you are collecting performance data for the first time, it takes longer than usual for XP Performance Advisor to collect the data. Subsequent performance data collection on the XP Disk Array is as per the time specified in the Frequency section. Requesting host update IMPORTANT: Perform this procedure only if you have made changes to your host agent or to the XP Disk Array connected to your host. If you have not made any changes at your host side, you can start collecting configuration and performance data. To request a host update: 1. Log in to XP Performance Advisor. For more information, see Launching XP Performance Advisor on page 66. 2. Click Array View in the left pane. 3. Click the Host Information tab on the Array View screen. 4. In the Host Information table, select the host agent records whose configuration details you want to update in XP Performance Advisor. HP StorageWorks XP Performance Advisor Software Installation Guide 97

5. Click Request Info. The Request Info button is enabled only when you select the host agent records. Use the Shft or Ctrl key to select multiple host agents. The request is executed in the subsequent data collection cycle. After XP Performance Advisor retrieves the latest information from the host, the Status changes to Received for the host agent record in the Host Information table. The latest time stamp is displayed under Updated. The version of the host agent installed on the host is displayed under HA Version. You can proceed to create a configuration data collection schedule. For more information, see Collecting configuration data on page 98. Collecting configuration data You can create a one-time configuration data collection or schedule it on a periodic basis. The procedure described here is for scheduling a configuration data collection. IMPORTANT: To perform configuration data collection for an XP Disk Array, select only one command device for that XP Disk Array. Do not initiate configuration data collection at the same time for multiple XP disk arrays. The Outband mode of configuration data collection is only supported for the XP10000, XP12000, XP20000, and XP24000 disk arrays. With every Outband mode of configuration data collection, XP Performance Advisor gets the latest internal raw disk capacity from your XP Disk Array (XP10000, XP12000, XP20000, XP24000) and updates its value under Array Capacity (TB) on the License screen. So, it is necessary that the SVP belonging to the particular XP Disk Array be online, accessible, and not locked by any other user or under maintenance. The internal raw disk capacity got through the Inband mode of configuration data collection is not accurate when compared to the value shown by RWC, and might lead to license violations. So, if you want the accurate internal raw disk capacity of your XP Disk Array (XP10000, XP12000, XP20000, or XP24000), HP recommends that you collect configuration data using the Outband mode. To schedule a configuration data collection: 1. Click the Configuration Collection tab on the Array View screen. 2. In the Configuration Collection table, select the command device record corresponding to the XP Disk Array for which configuration data should be collected. You can also click an XP Disk Array icon in the Available Arrays section to view the corresponding set of records highlighted under the Configuration Collection tab. The existing set of records are automatically sorted to display the command devices belonging to the selected XP Disk Array at the beginning of the Configuration Collection table. 98 Using XP Performance Advisor

3. Select Collection Period as Recurring. NOTE: To collect configuration data once, select One Time as the collection period. Figure 18 Configuration Data Collection. 4. Retain the Collection Type as OutBand (default selection), if you want XP Performance Advisor to directly collect data from an XP Disk Array through its SVP. The IP Address is automatically displayed for an XP Disk Array, if you have already registered the SVP with the respective management station. You can also manually enter the SVP IP address. Select the Collection Type as Inband, if you want RAID Manager Library (RMLib) to collect configuration data from an XP Disk Array, and transfer to XP Performance Advisor. The Inband mode of configuration data collection is supported for the XP1024/128, XP10000, XP12000, XP20000, and XP24000 disk arrays. IMPORTANT: Outband is the preferred mode of configuration data collection for an XP Disk Array of type XP10000, XP12000, XP20000, or XP24000. If the SVP on the XP Disk Array is accessible, HP recommends that you use the Outband mode of configuration data collection, as XP Performance Advisor receives the accurate internal raw disk capacity from the XP Disk Array (same as shown by RWC) through the Outband mode. Collect configuration data through the Inband mode for an XP Disk Array only if Outband mode of configuration data collection is not supported on that array. 5. Select the Collection Schedule as hourly, daily, weekly, or monthly. By default, the collection is scheduled weekly, every Sunday at 00:00 hours. 6. Click Submit. XP Performance Advisor collects configuration data for the XP Disk Array through the selected command device. The Collection Status displays the following message for the XP Disk Array: In progress...please wait HP StorageWorks XP Performance Advisor Software Installation Guide 99

The selected schedule type and frequency appear under Frequency. After the configuration data is collected for the specified frequency, the Collection Status shows Done, and the Last Collection displays the updated time stamp when XP Performance Advisor completes receiving the latest configuration data. The latest configuration data for an XP Disk Array is automatically updated in XP Performance Advisor. If there are new resources that you want to be monitored, you can enable the associated performance data collection schedules to automatically collect data for the new resources (RAID groups and ports). After configuration data collection, you can start collecting performance data of your XP Disk Array. For more information, see Collecting performance data on page 100. Collecting performance data To create a performance collection schedule: 1. Click the Performance Collection tab on the Array View screen. Alternatively, you can also click an XP Disk Array icon in the Available Arrays section to view the corresponding set of records highlighted under the Performance Collection tab. The existing set of records are automatically sorted to display those belonging to the selected XP Disk Array at the beginning of the Performance Collection table. 2. In the Performance Collection table, select the XP Disk Array record for which you want to schedule performance data collections. 3. Click Create. The Create button is enabled only when you select an XP Disk Array record under the Performance Collection tab. Based on whether it is the first or second performance data collection schedule that you are creating, XP Performance Advisor does the following validations and displays the appropriate error messages, if the validations fail: If it is the first performance data collection schedule for the selected XP Disk Array, XP Performance Advisor verifies if configuration data is already available for that XP Disk Array. If it is the second performance data collection schedule for the selected XP Disk Array, in addition to the above-mentioned point, XP Performance Advisor also verifies the following: Whether the second schedule is using a different port other than the one already used by the first schedule. Whether the same host is being used to communicate with the selected XP Disk Array. 4. Enter a schedule name in the Performance Schedule Name box. It should have a maximum of 32 alphanumeric characters. Special characters, such as underscore (_) and apostrophe ( ) can be used. You can also insert a space between the words. 100 Using XP Performance Advisor

. 5. In the respective resource type lists, select the check boxes for resources to collect their performance data. The following resource type lists are displayed: DKC Port RAID Groups THP Groups Snap Groups CA Journal Groups External RAID Groups NOTE: Selecting a ThP, Snapshot, or XP Continuous Access Journal volumes also provides the respective volume pool information. The THP Groups, CA Journal Groups, and Snap Groups resource type lists are displayed only if the corresponding resources are configured on the selected XP Disk Array. The External RAID Groups resource type list is displayed only if external volumes are attached to the selected XP Disk Array. Select the Select All check box in a particular resource type list box, if you want all the corresponding resources to be selected. The Select All check box is provided for each resource type list. Figure 19 Performance Data Collection 1 Resource type list. 6. Set the frequency in minutes for DKC, RG, and Port performance data collection by selecting the frequency from the respective Frequency list. HP StorageWorks XP Performance Advisor Software Installation Guide 101

7. Select the check box for Stagger Schedule if you want to stagger the data collection time at different intervals. The Stagger Schedule ensures that the load on the management server at any point is balanced, because data collection occurs for all XP disk arrays at varied points of time in the day and not every 15 minutes of the hour. 8. Select the Add new RAID Groups, Ports to this schedule check box, if you want the performance data collection schedule to automatically collect performance data for the new RAID groups or ports that are discovered during scheduled configuration data collection. If the Add new RAID Groups, Ports to this schedule check box is selected in the first schedule, it is automatically disabled in the second schedule. However, the new THP, Snapshot, XP Continuous Access Journal volumes, and External RAID groups are automatically added to only that performance data collection schedule, which is already collecting data for other virtual volumes belonging to the same XP Disk Array. 9. Click Save for the changes to take effect. Click Cancel, if you do not want to configure a schedule for the current selection. 10. Click Refresh to view the updated list of performance data schedules. The new schedule starts automatically and XP Performance Advisor starts collecting data for the selected resources.

Glossary ACP XP Continuous Access Cache XP Continuous Access Journal CHA CHIP CHP CLPR Array Control Processor. ACP handles the transfer of data between the cache and the physical drives held in the DKUs. ACPs work in pairs, providing a total of eight SCSI buses. Each SCSI bus associated with one ACP is paired with a SCSI bus on the other ACP pair element. In the event of an ACP failure, the redundant ACP takes control. Both ACPs work together by sharing the load. On XP models, such as the XP10000, this function is handled by the disk adapter on the MIX board. ACP was used on XP disk arrays before the advent of the XP24000 type arrays. With the introduction of XP24000, DKA replaced ACP. The HP StorageWorks XP Continuous Access is a software providing remote replication between XP disk arrays and is used for disaster recovery. XP Continuous Access is referred to as XP Continuous Access in official HP documents. A Cache is a high speed memory that is used to speed up the I/O transaction time. All reads and writes to the XP disk arrays are sent to the cache. The data is buffered in the cache until it is transferred to the physical disks or from the physical disks (with slower data throughput) is complete. The benefit of cache memory is that it speeds the IO/s throughput to the application. The larger the cache size, the greater the amount of data buffering that can occur and the greater throughput to the applications. In the event of power loss, the battery power maintains the contents of cache for a specified time period. The HP StorageWorks XP Continuous Access Journal is an asynchronous mirroring program similar to the XP Continuous Access Async Software, except that the transactions to be written to the secondary XP Disk Array are maintained in a disk-based journal file. This provides better performance for secondary XP Disk Array systems that are not highly available or that may be subject to bandwidth contention from other applications. Channel Adapter. CHA provides an interface between an XP Disk Array and the external host system. Occasionally, this term is used synonymously with the term channel host interface processor (CHIP). Client-Host Interface Processor. CHIP was used on XP disk arrays before the advent of the XP24000 type arrays. With the introduction of XP24000, CHIP replaced CHA. However, CHIP appears in documents written for array types prior to XP24000. Channel Processor. The CHP are the micro processors (MP)s located on the channel adapter (CHA). Synonymously used with CHIP. Cache Logical Partition. HP StorageWorks XP Performance Advisor Software Installation Guide 137

CLPR contains cache and parity groups, and is available on the XP12000, XP10000, and later generations of XP disk arrays. NOTE: CLPR0 always exists (cannot be deleted) and is a pool area for cache and parity groups that are not yet assigned to other CLPRs. CV CV AE CSV DFW DKA DKC DKP DKU DNS Emulation Modes Command View XP. The HP StorageWorks Command View XP Software is replaced by the HP StorageWorks Command View XP Advanced Edition software. Command View XP Advanced Edition. The HP StorageWorks Command View XP Advanced Edition software replaces the Command View XP (CV) software to manage XP disk arrays. Comma-separated value. DASD Fast Write. A DFW is a function of a storage controller that allows caching of active write data without exposure of data loss. This is achieved by journaling of the active write data in NVS. Disk Adapter. A DKA is a PCB in the XP Disk Array and manages the data transfer between the Cache and the physical drives in the backend. It is one of the two PCB types in the XP Disk Array that contains the micro processors. Disk Controller. The DKC is a frame in an XP subsystem and houses the channel adapters and Service Processor (SVP). Disk Processor. The DKP is the name for a micro processor located on the DKA. Disk Unit. The DKU is the XP Disk Array's hardware that houses the XP Disk Array's physical Hard Disk Drive (HDD). Domain Name System. DNS corresponds to the [servername].[domain name] of your system. The logical devices (LDEVs) associated with each RAID group are assigned an emulation mode that makes them operate like OPEN system disk drives. The emulation mode determines the size of an LDEV. OPEN-3: 2.46 GB OPEN-8: 7.38 GB OPEN-9: 7.42 GB OPEN-E: 13.56 GB OPEN-K: (Not available on this array) OPEN-L: 36 GB OPEN-M: (Not available on this array) 138 Glossary

OPEN-V: User-defined custom size Inband data collection JRE HPAC LDAP LDEV LUN Outband RADIUS RADIUS VSA R/W RAID Group A method of collecting configuration data for an XP Disk Array using a command device that is presented to a host operating system. Java Run time. Hewlett-Packard Authorization Center Hewlett-Packard Authorization Center license key website (http:// webkey.external.hp.com/), where you generate a license for a specified internal raw disk capacity of your XP Disk Array. Lightweight Directory Access Protocol. The LDAP is used for centralized authentication, where the LDAP server authenticates and authorizes XP Performance Advisor users. Logical Device. An LDEV is created when a RAID group is divided into smaller partitions or volumes according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-9). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term Volume. Logical Unit Number. A LUN is created by mapping a SCSI logical unit number, port ID, and an LDEV ID to a RAID group. It is always associated with a single LDEV and presented to a host. The optional LUSE feature allows a LUN to be associated with 1 to 36 LDEVs. Thereby, enabling for applications to access a single large pool of storage. The Outband mode uses Remote Method Invocation (RMI) to collect data from an XP Disk Array through its SVP, where XP Performance Advisor directly communicates with the XP Disk Array to collect its configuration data. Outband is the preferred mode of configuration data collection for an XP Disk Array of type XP10000, XP12000, XP20000, or XP24000. If the SVP on the XP Disk Array is accessible, HP recommends that you use the Outband mode of configuration data collection, as XP Performance Advisor receives the accurate internal raw disk capacity from the XP Disk Array (same as shown by RWC) through the Outband mode. Using the OutBand mode ensures that the performance of Storage Area Network (SAN) is not affected because of data collection. Remote Authentication Dial In User Service. The RADIUS Authentication is a networking protocol that provides centralized authentication, where the RADIUS server authenticates and authorizes XP Performance Advisor users. RADIUS Vendor Specific Attribute. The VSA is required for authorizing XP Performance Advisor users for RADIUS Authentication. It must have a vendor ID of 11 that is assigned to Hewlett-Packard by IANA and an attribute type of 1. Your system administrator must add a RADIUS Vendor-Specific Attribute (VSA) to the user profile on the RADIUS server. Read/Write (r/w) operations. A RAID group is a group of 4 or 8 physical hard disk drives (HDDs) installed in an XP Disk Array and assigned a common RAID level. HP StorageWorks XP Performance Advisor Software Installation Guide 139

RAID1 array groups consist of 4 HDDs (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk, but also consist of 4 HDDs (3D+1P) or 8 HDDs (7D+1P). RAID6 array groups are made up of 8 HDDs (6D+2P). RML RWC SAN Side file SLPR Snapshot SSL SVP XP RAID Manager Library (RMLIB). The XP RML or XP RMLIB is an API library that enables third party software products to directly operate some of the functions on the XP subsystem. XP Remote Web Console. XP Remote Web Console is the interface for various Java applications and it enables you to remotely manage the storage system. Storage Area Networks. The Side file is an area of the XP cache that has been set aside specifically for replication related activities that use Business Copy (BC) and XP Continuous Access. Storage Logical Partition. Partition of a RAID500 to which host ports (1 or more) are assigned, as well as CLPRs (1 or more). SLPR0 will always exist (cannot be deleted). Sometimes, the SLPR acronym includes an additional word. For example, Storage administrator Logical Partition or Storage management Logical Partition, both mean the same. The purpose of the SLPR is to allow multiple administrators to manage a subsystem without risk of causing mistakes that can destroy another user's volumes, or reduce other user's expected performance by using more resources (e.g. cache) than they should. Snapshot is a BC volume type which depicts a point-in-time copy of the original volume (PVOL). Secure Socket Layer. Service Processor. The SVP is a PC built into the XP disk controller and provides a direct interface into the XP Disk Array. NOTE: The access to SVP is reserved for HP authorized service personnel only. ThP (also TP) Trap TSM Thin Provisioning. Using ThP, you can operate with a global pool of LDEVs that are not assigned to physical storage. The disk arrays add virtual capacity from the pool of LDEVs as and when the data is written, and only at that time is physical capacity assigned to LDEVs and used for storage. An SNMP agent initiates trap operations when R-SIMs occur, to send the R-SIMs to the SNMP manager. An SNMP agent can be configured to deliver traps to more than one SNMP manager. XP Tiered Storage Manager. 140 Glossary

The XP Tiered Storage Manager software is used to perform migration, where data stored on one volume is moved to another volume. XP Tiered Storage Manager software moves data on predefined set of volumes to another set of volumes with the same characteristics. For more information, see the manuals set provided for XP Tiered Storage Manager software on the HP Manuals page. UAC XP Performance Advisor User Access Code. UAC controls the installation and removal of programs, and prevents programs from being added to the registry on a Windows Vista system. So, disable UAC before installing XP Performance Advisor on a Windows Vista management station. XP Performance Advisor.
