Other Requirements The EMC CLARiiON PRO Storage System Performance Management Pack in order to perform PRO recovery actions has the following other requirements. CLARiiON command line interface (CLI) is must be installed on the SCOM Management Server. Run the Naviseccli installation program. To check what version of the command line interface (CLI) that you have installed execute naviseccli -help in a command shell. Security credentials for accessing the storage systems must be stored on the SCOM Management Server. To create and save the credentials perform the following steps: o o Log on to the SCOM server. Add the storage system administration account(s) to the security file by executing the following in a command shell. naviseccli -AddUserSecurity -scope 0 -user Username -password Pswd Note: This will create the security files SecuredCLISecurityFile.xml and SecuredCLIXMLEncrypted.key in your %USERPROFILE% path. Scope can be either local or global. Here we show global. Check your storage system domain administration accounts for their correct scoping. o o Copy the security files SecuredCLISecurityFile.xml and SecuredCLIXMLEncrypted.key from your %USERPROFILE% path to the Navisphere CLI installation folder i.e. C:\Program Files (x86)\emc\navisphere CLI. Delete the security files from your %USERPROFILE% path. A LUN must be manually pre-provision for storage migration on each CLARiiON storage system that is supporting a managed Hyper-V server. The LUN should be at least 2 GB larger than any of the LUNs currently in use by the Hyper-V server. Use either the Navisphere or Unisphere Manager, depending on your FLARE version, to create the LUN. Append to the name of the new LUN the following text - PRO Storage Migration. 9

10 Virtual Disk Service (VDS) support is required on the SCOM Management Server and on each storage system host that is supporting a managed Hyper-V server. Install the EMC Hybrid VDS Hardware Provider or later by running the Solution Enabler (SE) VDS installation program version or later. VDS must be configured with each CLARiiON storage system that the host will manage. See the EMC VDS Provider Release Notes, on EMC Powerlink, for using the symcfg utility to authorize and discover CLARiiON storage systems. File microsoft.storage.vds.dll, Microsoft Storage VDS.NET library version , file version , or later, should be available on all Windows Server 2008 R2 machines. A CLARiiON Storage System Configuration file. This file can be created by performing the following steps: o Get EMC storage system serial number to management port IP Address mapping. This can be done by executing the following Naviseccli command for each storage system. The IP address is for one of the storage system management ports. C:\Users\administrator.SR5DOM>naviseccli -address domain -list Node: APM IP Address: Name: B-IMAGE Port: 80 Secure Port: 443 IP Address: (Master) Name: A-IMAGE Port: 80 Secure Port: 443 C:\Users\administrator.SR5DOM>naviseccli -address domain -list Node: APM IP Address: (Master) Name: A-IMAGE Port: 80 Secure Port: 443 IP Address: Name: B-IMAGE Port: 80 10

11 Secure Port: 443 o o Create a simple empty text file named ClarStorageSystems.cfg in the Navisphere CLI installation folder. Add to the configuration file the storage system serial number and management port as shown below. Note that both management ports have been added for the first storage system and while only one for the second. Which management ports you add depends on how you want or need to control access to the storage system. APM , APM , APM , How to Import the EMC CLARiiON PRO Storage System Performance Management Pack For instructions about importing a management pack, see How to Import a Management Pack in Operations Manager 2007 ( After the EMC CLARiiON PRO Storage System Performance Management Pack is imported, for each of the following management packs, create a new management pack in which to store overrides and other customizations or import the one provided. 1. EMC CLARiiON PRO Storage System Performance Management Pack EMC CLARiiON PRO Storage System Performance Overrides EMC.CLARiiON.PRO.StorageSystem.Performance.Overrides.xml Version: Microsoft Windows Hyper-V 2008 Discovery Management Pack Microsoft Windows Hyper-V 2008 Discovery Overrides Microsoft.Windows.HyperV.2008.Discovery.Overrides.xml Version: Microsoft Windows Hyper-V 2008 Monitoring Management Pack 11

12 Microsoft Windows Hyper-V 2008 Monitoring Overrides Microsoft.Windows.HyperV.Monitoring.Overrides.xml Version: Create a New Management Pack for Customizations Most vendor management packs are sealed so that you cannot change any of the original settings in the management pack file. However, you can create customizations, such as overrides or new monitoring objects, and save them to a different management pack. By default, Operations Manager 2007 saves all customizations to the default management pack. As a best practice, you should instead create a separate management pack for each sealed management pack you want to customize. Creating a new management pack for storing overrides has the following advantages: It simplifies the process of exporting customizations that were created in your test and preproduction environments to your production environment. For example, instead of exporting a default management pack that contains customizations from multiple management packs, you can export just the management pack that contains customizations of a single management pack. You can delete the original management pack without first needing to delete the default management pack. A management pack that contains customizations is dependent on the original management pack. This dependency requires you to delete the management pack with customizations before you can delete the original management pack. If all of your customizations are saved to the default management pack, you must delete the default management pack before you can delete an original management pack. It is easier to track and update customizations to individual management packs. Optional Configuration Depending upon how dynamic your virtualized environment is and existing Service Level Agreements (SLAs), you may need to adjust certain discovery and monitoring rules within the management pack. All rules are enabled by default. Configuring Discovery Rules The following EMC CLARiiON PRO Storage System Performance Management Pack discovery intervals should be tuned to how frequently your environment is changing. If a default value is not appropriate for your environment, you should adjust the value overriding it. 12

13 Rule Name CLARiiON Storage System Host Discovery Virtual Machine Discovery Interval (seconds) Default Value (4 hours) (4 hours) Also, in the Microsoft Windows Hyper-V 2008 Discovery Management Pack is the following discovery for a Hyper-V 2008 Virtual Machine that the Free Disk Space Collection Rule in the Microsoft Windows Hyper-V 2008 Monitoring Management Pack is targeted against. Rule Name Hyper-V 2008 Virtual Machine Discovery Interval (seconds) Default Value (12 hours) Collection Rules The following Microsoft Windows Hyper-V 2008 Monitoring Management Pack collection interval should be tuned to how frequently your environment is changing. If a default value is not appropriate for your environment, you should adjust the value overriding it. Rule Name Interval (seconds) Default Value Category Free Disk Space Collection Rule 3600 (1 hour) State Collection Security Considerations The EMC CLARiiON PRO Storage System Performance management pack has no special security considerations other than having storage system credentials stored on hosts. See previous section on Other Requirements. Low-Privilege Environments A low-privilege agent action account must meet the following requirements: Member of the local administrators group on the Hyper-V servers and SCOM Server. The following management pack tasks cannot be run using a low-privilege account. These tasks require that the Action account have Admin user rights on the agent computer: Discoveries Monitors Recoveries 13

14 Run As Profiles Discoveries, Monitors and Write Action Modules all use Default Run As profile. Data Source Modules use System.PrivilegedMonitoringAccount profile. Understanding Management Pack Operations The EMC CLARiiON PRO Storage System Performance Management Pack monitors Hyper-V servers that are experiencing storage issues with CLARiiON volumes being used to host VHD files. Objects the Management Pack Discovers In addition to the boilerplate text below, you should include information about object discoveries that will help your customer deploy the management pack. For example, if one type of discovery before the next object type is discovered, it s helpful for the customer to know that, and also to know how long (by default settings) it will take for complete discovery. The EMC CLARiiON PRO Storage System Performance Management Pack discovers the object types described in the following table. All of these objects are automatically discovered. Use overrides to tune their discovery intervals or disable their discovery. For information about discovering objects, see the "Object Discoveries in Operations Manager 2007" topic in Operations Manager 2007 Help ( Discovery Name Object Type Interval (seconds) Default Value CLARiiON Storage System Host Discovery CLARiiON Storage System Host (4 hours) Virtual Machine Discovery Hyper-V Virtual Hard Disk (4 hours) CLARiiON Storage System Host CLARiiON Storage System Host Logical Disk CLARiiON Storage System Host Computer Group Discovery PRO Critical Alerts Host Group Health Discovery PRO Warnings and Critical Alerts Host Group Discovery CLARiiON Storage System Host Computer Group CLARiiON Storage System Hosts Enabled for Critical PRO Tips Group CLARiiON Storage System Hosts Enabled for Warning and Critical PRO Tips Group SCOM On Demand SCOM On Demand SCOM On Demand 14

15 CLARiiON Storage System Host Group Discovery PRO Automatic Recovery Critical Alerts Host Group Discovery PRO Automatic Recovery Warnings and Critical Alerts Host Group Discovery CLARiiON Storage System Host Group CLARiiON Storage System Hosts Enabled for Automatic Implementation of Critical PRO Tips Group CLARiiON Storage System Hosts Enabled for Automatic Implementation of Warning and Critical PRO Tips Group SCOM On Demand SCOM On Demand SCOM On Demand Use the following procedure to enable or disable automatic discovery. The procedure enables the SQL 2005 Agent Job as an example. To use an override to change the setting for automatic discovery 1. In the Authoring pane, expand Management Pack Objects, and then click Object Discoveries. 2. On the Operations Manager toolbar, click Scope, and then filter the objects that appear in the details pane to include only CLARiiON Storage System Host objects. 3. Under Object Discoveries click CLARiiON Storage System Host Discovery. Note: In Operations Manager 2007 R2, click Change Scope. 4. On the Operations Manager toolbar, click Overrides, click Override the Object Discovery, and then click For all objects of class: PRO Hyper-V Host Target. 5. In the Overrides Properties dialog box, click the Override box for the Interval in seconds parameter and enter the desired value in Override Value column. 6. Under Management Pack, click New to create an unsealed version of the management pack, and then click OK, or select an unsealed management pack that you previously created in which to save this override. As a best practice, you should not save overrides to the Default Management Pack. After you change the override setting the object type will now be discovered using the new interval value. Classes The following diagrams show the class inheritance and relationships defined in this management pack. 15

18 How Health Rolls Up Performance health is rolled up to the CLARiiON Storage System Host and then to respective groups depending on the monitoring context. CLARiiON Storage System Host Computer Group CLARiiON Storage System Hosts Enabled for Critical PRO Tips Group CLARiiON Storage System Hosts Enabled for Warning and Critical PRO Tips Group CLARiiON Storage System Host Group CLARiiON Storage System Hosts Enabled for Automatic Implementation of Critical PRO Tips Group CLARiiON Storage System Hosts Enabled for Automatic Implementation of Warning and Critical PRO Tips Group Rollup to the CLARiiON Storage System Host is as follows: Logical Disk for Host Performance Health Rollup: this is a dependency monitor that rolls up CLARiiON Storage System Host Logical Disk performance to the host. Virtual Hard Disk Free Disk Space Health Rollup: This is a dependency monitor that rolls up Hyper-V 2008 Virtual Machine health to its CLARiiON Storage System Host Logical Disk. Virtual Hard Disk free disk space: this is a unit monitor that changes state based on available disk space on a logical disk. Key Monitoring Scenarios The EMC CLARiiON PRO Storage System Performance Management Pack supports monitoring CLARiiON storage system issues for Hyper-V servers. The following table lists some of those monitoring scenarios and indicates the elements that can be modified. Scenario Low Disk Space for VMs Configurable Elements The Virtual Hard Disk free disk space monitor is targeted at the Hyper-V Virtual Hard Disk. It is configured, by default, to enter a Warning State when the available free space on a logical disk falls below 2048 MB or 2 GB. The Critical State is entered when space falls below 2 MB. The management will provide remediation when the monitor enters the Critical State. 18

19 Troubleshooting Scripts contained within the EMC CLARiiON PRO Storage System Performance Management Pack will raise events in the Windows Application Log using an event source of EMC.CLARiiON.PRO.StorageSystem.Performance.
