Read the current revision of the Release Notes for the most recent information about: Supported and required software and firmware releases. Supported operating system versions. The latest information about Host Integration Tools known issues and usage constraints. On a single computer, you must log in to Windows as administrator or be a member of the administrators group to install and use the Host Integration Tools. When installing on a cluster, you must run the installation from an account that is a member of the domain administrators group. Note: If a previous version of a component is already installed on your computer, the installation program updates it to the latest version. Host Integration Tools Components The Host Integration Tools installation program enables you to choose which components to install on your computer. The components are listed in Table 1-1. Table 1-1: Host Integration Tools Components Component Remote Setup Wizard Remote Setup Wizard Command Line Utility (RSWCLI) Dell Auto-Snapshot Manager/ Microsoft Edition (ASM/ME) EqualLogic VSS Provider Description Enables you to initialize a PS Series SAN array and set up or expand a PS Series group. You can also configure multipath I/O. See Chapter 2, Remote Setup Wizard. Provides an alternative to using the Remote Setup Wizard, with set up commands that you can execute at the Windows command prompt instead of using the GUI. The RSWCLI is described in Chapter 3, Remote Setup Command Line Utility. A Microsoft Management Console (MMC) snap-in tool that enables you to create and manage Smart Copies (snapshots, clones, and replicas). An alternate command-line interface facilitates custom operations and scripting. See the Auto-Snapshot Manager/ Microsoft Edition User s Guide Supports VSS management of application-consistent Smart Copies. 1 1

Installation Table 1-1: Host Integration Tools Components (Continued) Component EqualLogic VDS Provider EqualLogic Multipath I/O DSM (MPIO DSM) Microsoft iscsi Initiator iscsi Initiator properties tab Java Runtime Environment Description Enables you to use Microsoft VDS and Microsoft Storage Manager for SANs to create and manage volumes in a PS Series group. See Chapter 5, Using the VDS Provider. A driver module that works in conjunction with the Microsoft MPIO driver to support multipathing. This feature dynamically balances your iscsi SAN traffic load over multiple network paths between the computer and the PS Series group. You need multiple iscsi host bus adapters to use this feature. Configure EqualLogic Multipath I/O DSM by using the Remote Setup Wizard, as described in Chapter 2, Remote Setup Wizard. As an alternative to the Remote Setup Wizard, you can use the RSWCLI, described in Chapter 3, Remote Setup Command Line Utility. Enables connections to iscsi targets.

Supported Applications The applications described here are supported for use with Host Integration Tools, subject to any issues and constraints specified in the Release Notes. Microsoft Exchange Server Host Integration Tools supports online backup and quick restore of Exchange components by using the ASM/ME GUI. The installer verifies that a supported version of Microsoft Exchange Server exists on the target installation computer. If the installed version is not supported, you have the following options: Cancel the ASM/ME installation and update Microsoft Exchange Server. Proceed with the ASM/ME installation. In this case, ASM/ME operations that are specific to Microsoft Exchange Server will not function until you have updated to a supported version. Note: If ASM/ME detects an unsupported version of Microsoft Exchange Server, a red arrow appears next to the application in the ASM/ME console tree. Supported features for Microsoft Exchange Server include: Creating snapshot, replica, and clone Smart Copies of Microsoft Exchange Server mailbox databases (for Exchange 2010) or storage groups (for Exchange 2007 and 2003) residing on PS Series volumes. Automatic discovery of the Microsoft Exchange Server instance and its components. Consistent, online backup and quick restore of Microsoft Exchange mailbox databases (for Exchange 2010) or storage groups (for Exchange 2007 and 2003) residing on PS Series volumes The following types of Microsoft Exchange Server application behaviors are supported for Smart Copies: 1 2

Installation Copy backup type (on Microsoft Exchange Server 2010, 2007 and 2003 sp2). Scheduling Smart Copy creation for Microsoft Exchange mailbox databases (for Exchange 2010) or storage groups (for Exchange 2007 and 2003). Recovery Mailbox Database creation for Microsoft Exchange 2010 item level restores. Automated Recovery Storage Group setup for Microsoft Exchange 2007 item level restores. Recovery Storage Group creation setup for Microsoft Exchange 2003 item level restores. The Clone and Restore All as New option is available for Microsoft Exchange 2010 and 2007 Smart Copies. The Clone and Restore All as New feature allows you to clone a mailbox database from a source Exchange server, and then set it up as a new mailbox database on a target Exchange server. The option to perform checksum verification (database and transaction log) and optional soft recovery immediately after Smart Copy creation. You can also use this feature by setting up a global verification task on the Exchange Server host or a remote host. See the ASM/ME User Guide for more information. Microsoft SQL Server Host Integration Tools supports online backup and quick restore of Microsoft SQL Server databases using the Auto-Snapshot Manager/Microsoft Edition (ASM/ME) GUI. Although it is not detected during installation, ASM/ME verifies the compatibility of the installed version of SQL Server. The ASM/ME Applications writer node is disabled if the installed version and service pack level of Microsoft SQL Server is unsupported. Supported Microsoft SQL Server versions with required service pack updates are described in the Release Notes. Note: If ASM/ME detects an unsupported version of Microsoft SQL Server, a red arrow appears next to the application in the ASM/ME console tree. Supported features for Microsoft SQL Server include: Support for creating snapshots, replicas, or clones of Microsoft SQL Server databases residing on PS Series volumes. Automatic discovery of Microsoft SQL Server instance and all SQL databases. Consistent, online backups and quick restores of Microsoft SQL Server databases residing on PS Series volumes. Microsoft SQL Server application supports both full and copy backup type Smart Copies on Microsoft SQL Server 2005 and 2008. The following Microsoft SQL Server database restore operations are supported: Restore All - Restores databases to the point-in-time represented by a Smart Copy. Optionally, you can apply transaction log backups to a database being restored. Restore named_databases - Selectively restores one or more databases sharing the same volume (uses an automated file copy operation after the Smart Copy is imported, if volume sharing is detected). Restore All as New - Restores all databases as new databases with new mount points. 1 3

Installation Clone and Restore as New - Recovers a database from a cloned replica Smart Copy on the secondary group. Optionally, you can mount a read-only copy of the replica Smart Copy for backup to tape or for data mining (volume replication stops while replica is mounted). See the ASM/ME User Guide for more information. Microsoft Hyper-V Hyper-V enables you to run a client virtual machine (also called a guest O/S) in child partitions. ASM/ME enables you create application-consistent and crash-consistent Smart Copies of virtual machines, dependent on Guest O/S type. You can also: Define collections of virtual machines. Set up schedules for creating Smart Copies of virtual machines. Restore Smart Copies of virtual machines. Restore virtual hard drive (VHD) volumes. See the ASM/ME User Guide for more information. Installing Host Integration Tools on a Microsoft Failover Cluster The following parallel installation requirements apply when you configure the Host Integration Tools on more than one node in the Microsoft Failover Cluster: You must install the same version of Host Integration Tools on every cluster node. You must select the same set of components (such as ASM/ME or VDS) on each node. You must run the Remote Setup Wizard on each node, specifying identical responses for each screen. If you are using multipathing with the EqualLogic MPIO DSM, you must use an identical configuration on each node. Considerations when Configuring Failover Clusters Information on configuring, using and troubleshooting Microsoft Failover Clusters can be found on Microsoft's TechNet website. Computers running Windows Server 2003 and using the cluster service might be unable to join a cluster after the computer is first restarted. See the Microsoft Knowledgebase article at: http://support.microsoft.com/kb/938615 The cluster service might not start after you restrict the available IP Ports for remote procedure calls. See the Microsoft Knowledgebase article at: http://support.microsoft.com/kb/258469 In a server cluster that uses only iscsi technology for shared storage devices, you must make the cluster service dependent on the Microsoft iscsi Initiator service. This makes the Microsoft iscsi Initiator service 1 4

Installation start before the cluster service. See the Microsoft Knowledgebase article at: http://support.microsoft.com/kb/883397 When you start your Microsoft Windows Server 2003-based computer that is running Windows Clustering, an Event ID: 57 might be logged. See the Microsoft Knowledgebase article at: http://support.microsoft.com/default.aspx/kb/885688/en-us See also the ASM/ME User s Guide for information about configuring ASM/ME for use on Windows Failover Clusters and for information about cluster resource ownership. Joining a Computer into a Windows Failover Cluster The following considerations apply when you join a single computer running Host Integration Tools into a Microsoft Failover Cluster: If you are using continuous cluster replication (CCR) or a Database Availability Group (DAG) under Microsoft Exchange, you do not need to supply Host Integration Tools with cluster access information during the installation. You are prompted to check a box during the installation indicating that CCR or DAG is in use and subsequently you do not need to supply a user name or password. You must maintain parallel installations (see Installing Host Integration Tools on a Microsoft Failover Cluster on page 1-4) You must use an account with the correct credentials (see ASM/ME Cluster Administrative Account on page 1-5) You must change the logon account for the EQLReqService (see Changing the EqlReqService Logon Account on page 1-6) Note: If you install Host Integration Tools on a running cluster, you are prompted to configure the installation for cluster operation and it is not necessary to complete the tasks described in the following sections. ASM/ME Cluster Administrative Account You perform many operations across cluster nodes. Therefore, you must log in using a user account that has the following characteristics: The account is a Microsoft domain user account The account has local administrative access Consider creating a named account such as ASMadmin to use for ASM/ME operations on the cluster. You can use this account to log on to required services as described in Changing the EqlReqService Logon Account on page 1-6. If any cluster node is running Microsoft Exchange and Microsoft SQL Server, (using PS Series iscsi volumes) you must also make sure that your user account has the appropriate security group access for those applications. Note: Certain operations may fail with an error message if you do not use an appropriate account. 1 5

Installation Changing the EqlReqService Logon Account To join a system running Host Integration Tools to a cluster, you must change the logon for the EQLReqService. Use the ASM/ME cluster administrative account referenced in ASM/ME Cluster Administrative Account on page 1-5. 1. Open the Windows Control Panel 2. Double-click Administrative Tools. 3. Double-click Services. The Services window appears. 4. Double-click EQLReqService. 5. Select the Log On tab and change the logon account to the ASM/ME administrative account, or any account with appropriate access credentials. PS Series Group Network Recommendations Table 1-2 describes the network recommendations for PS Series group operation and for computer access to group. All the normal networking rules apply; however, network configuration is beyond the scope of this manual. Table 1-2: PS Series Group Network Recommendations Recommendation Switched Gigabit Ethernet network Network switch types Description Connect arrays and computers to a switched network. Dell recommends that all network connections between computers and arrays are Gigabit Ethernet. (An array can operate at 10 and 100 Mbits, but performance will be significantly degraded.) Network interface cards (NICs) or host bus adapters (HBAs) must operate at a minimum of 1 gigabit per second (1Gb/sec). NICs that operate at speeds of less than 1Gb/sec are not used for multipath I/O by default. Dell recommends using enterprise class switches of a non-blocking design for your iscsi SAN. If using multiple switches, link the switches to enable communication across different subnets. Use a link of sufficient bandwidth. Multiple network connections For increased bandwidth and availability, connect multiple network interfaces on an array to the network (use different switches, if possible). Connect interfaces in the following order: Port 0, Port 1, and Port 2. Multiple network connections are required for multipath I/O. The initial group setup configures only one network interface on an array (Port 0). After creating the group, use the Group Manager GUI or CLI to assign an IP address and netmask to other network interfaces. Access to the group IP address Redundant network paths In a multi-subnet group, each configured network interface should have access to the subnet on which the group IP address resides. Multipath I/O provides a highly-available network path between computers and arrays. For replication, a reliable, adequately sized network link For effective and predictable replication, make sure that the network link between the primary and secondary groups is reliable and provides sufficient bandwidth for copying data. Flow Control enabled on switches and NICs Enable flow control on each switch port and NIC that handles iscsi traffic. PS Series arrays will correctly respond to Flow Control. 1 6

Installation Table 1-2: PS Series Group Network Recommendations (Continued) Recommendation Unicast storm control disabled on switches Jumbo Frames enabled on switches and NICs No STP functionality on switch ports that connect end nodes Description Disable unicast storm control on each switch that handles iscsi traffic, if the switch provides this feature. However, the use of broadcast and multicast storm control is encouraged on switches. Enable jumbo frames on each switch and NIC that handles iscsi traffic to obtain performance benefits and for consistency of behavior. Do not use spanning-tree (STP) on switch ports that connect end nodes (iscsi initiators or storage array network interfaces). However, if you want to use STP or RSTP (preferable to STP), you should enable the port settings available on some switches that let the port immediately transition into STP-forwarding state upon linkup. This can reduce network interruptions that occur when devices restart, and should only be enabled on switch ports that connect end nodes. Dell encourages you to use spanning-tree for a single-cable connection between switches and also to use trunking for multi-cable connections between switches. VLANs Configure network switches to use VLANs to separate iscsi SAN traffic from other network traffic. Installing the Host Integration Tools This section describes the prerequisites for an installation and guides you through the graphical installation procedure. Installation Considerations Consider the following before you begin an installation: Microsoft iscsi Initiator Version Host Integration Tools supports specific versions of the Microsoft iscsi Initiator as described in the Release Notes. Depending on the version currently installed on your computer, you might be required to update to a more recent version. Some Windows operating system variants include the Microsoft iscsi Initiator as a service. Using a Firewall If you are using a firewall and you intend to install the EqualLogic Multipath I/O DSM, you must configure the firewall to allow ICMP echo requests (pings). See the Release Notes for more information. Note: If your computer is running Windows Server 2008 or Windows Server 2003, the installation procedure detects whether you are using a firewall service and offers to automate Windows firewall configuration. Computer Downtime You do not need to reboot the computer unless you choose to install the MPIO DSM component. Be aware that rediscovery of the network after a shutdown might take several minutes. Installation Options Review the documentation (this manual and the Release Notes) to determine: Whether you require a typical installation or a custom installation. Whether Host Integration Tools supports the installed applications and operating system versions. 1 7

Installation Which Host Integration Tools components are applicable to your site. Installation Location Decide whether you want to install the Host Integration Tools in the default location of C:\Program Files\EqualLogic, or a different location. See also the specific requirements for ASM/ME operations in the ASM/ME User Guide. Windows Server 2008 Installation Considerations If you are installing Host Integration Tools on a computer running Windows Server 2008, review the requirements and support statements included in the Release Notes. During the installation, you might be prompted to perform the following configuration tasks, depending on the current state of your Windows installation: Microsoft iscsi Initiator service The Microsoft iscsi Initiator is integrated into Windows Server 2008 rather than provided as an installation package. During the installation of Host Installation Tools, you have the option to start the Initiator service. When started, the installer launches the Initiator properties interface so that you can optionally configure connections to your SAN. Close the Initiator properties interface to continue with the Host Integration Tools installation. Windows Firewall and Equallogic MPIO This consideration applies only if you decide to use EqualLogic MPIO. If Windows Firewall is enabled, you must configure it to allow echo requests (pings). During the installation of Host Installation Tools, you have the option to configure the firewall automatically. Microsoft MPIO service This consideration applies only if you decide to use EqualLogic MPIO. Microsoft MPIO service is required to run MPIO. During the installation of Host Installation Tools, you have the option to configure the MPIO service automatically. If you decide not to configure any of these services during the Host Integration Tools installation, you must configure them as a post-installation task. Otherwise, the related Host Integration Tools features will not function. For example, you cannot run Remote Setup Wizard to set up EqualLogic MPIO if you did not opt to start the Microsoft MPIO service. Windows Server 2008 Core Additional Considerations If you are installing Host Integration Tools on a computer running Windows Server 2008 Core, review the requirements and support statements included in the Release Notes. Because Windows Server 2008 Core does not provide a Desktop graphical user interface, you must begin the installation as follows: 1. Copy the installation package (such as setup64.exe) to a location on the computer. Write down the path to the file. 2. Connect to the computer running Windows Server 2008 Core and open the Windows command line terminal. 3. Type the following command and press enter: run <pathname>setup64.exe. 1 8

Installation 4. The Host Installation Tools graphical installer launches. Follow the procedure described in First Time Installation Summary on page 1-9. Only supported components are installed. Note: To uninstall Host Integration Tools from a computer running Windows Server 2008 Core, run the installation package a second time and select the option to Modify the current installation. Preparing to Install Obtain the installation kit by using one of the following methods: Find the Host Integration Tools distribution CD-ROM that shipped with your PS Series array. The CD-ROM uses autorun to start automatically (if your computer is configured to allow autorun). Download the installation kit (approximately 60MB for the 32-bit version and 91MB for the 64-bit version). This requires a EqualLogic Customer User account, which you can set up at the following URL: https://support.dell.com/equallogic. When you have set up the support account, obtain the kit as follows: 1. Log in to your account and click the Customer Service Home tab. 2. Click Downloads in the navigation bar and select Host Integration Toolkit. 3. Click the latest revision of the toolkit to display the Web page for that revision. 4.

Save the executable installation image to a temporary location on your local computer. First Time Installation Summary If you have installed a previous version the Host Integration Tools, see Updating, Maintaining, and Removing an Installation on page 1-11 for information about modifying or updating an existing installation. When installing on a failover cluster, you must perform the installation from an account that is a member of the domain administrator group. Follow the prompts on the CD-ROM installation dialog or double-click the downloaded setup.exe package to start the installation. A summary of each installation window is provided in Table 1-3: Table 1-3: Installation Summary Window Title Host Integration Tools Welcome Screen License Agreements User Actions and Options The installer detects unsupported versions of related applications, such as Microsoft Exchange. You can abort the installation and update the applications to supported revisions, or proceed and defer the application update to a later time. Click Next to proceed. You are prompted to read and accept the EqualLogic license and associated product licenses for third-party software. 1 9

Installation Table 1-3: Installation Summary (Continued) Window Title Installation Type Microsoft iscsi Initiator Service. Choose Destination Location (custom installations only). [Optional] Windows Firewall Configuration Select Components (custom installations only). Cluster Access Information (failover clusters only). User Actions and Options Choose a Typical (the default) or a Custom installation. A Typical installation automatically installs the Multipath I/O software (where supported), which requires a post-installation reboot. A custom installation allows you select which components are installed, depending on which version of Windows you are using. Depending on which version of Windows you are using, you might be prompted to start the Initiator service. Close the Initiator properties interface to resume the installation. Specify an installation folder for the kit, or accept the default location on the system C:\ drive. To use EqualLogic MPIO, you must configure the Windows Firewall. The Installer performs this configuration automatically, or you can defer it as a post-installation task. (If you defer firewall configuration, you must configure the firewall manually before you run the Remote Setup Wizard to configure MPIO.) Specify which components you want to install. (A reboot is required for installations that include the EqualLogic MPIO DSM.) Specify the name and password of a domain account with the credentials described in ASM/ME Cluster Administrative Account on page 1-5. Specify a network file share for the ASM/ME backup documents using UNC format (\\host\folder). Ready to install the components [Optional] Microsoft MPIO Service Installation Status Installation Complete You can proceed to install or click Back to optionally review your selections. Click Cancel to abort the installation. To use EqualLogic MPIO, you must configure the Windows MPIO service. The Installer performs this configuration automatically, or you can defer it as a post-installation task. (If you defer configuring the MPIO service, you must configure it manually before you run the Remote Setup Wizard to configure MPIO.) The installer displays the installation progress. If the installer encounters any problems, dialog messages guide you through the recovery process. If any unrecoverable problems occur, one or more diagnostic messages might appear as part of this sequence. Write down these messages for troubleshooting purposes. You can run the Remote Setup Wizard, which launches immediately if no system reboot is required. A reboot is mandatory to restart the MPIO DSM component and the Remote Setup Wizard launches automatically when the reboot is complete. Note: If you deferred the task of configuring services such as the Microsoft iscsi Initiator service or the Microsoft MPIO service, configure the services manually before you launch the Remote Setup Wizard. The related Host Integration Tools components will not work until the required services are running. 1 10

Installation Updating, Maintaining, and Removing an Installation After you have installed the Host Integration Tools for the first time, running the same installation procedure subsequently enables you to do the following tasks: Add and remove components. For versions of Windows that have a desktop GUI, remove most of the components originally installed. To completely remove all components, use the software management option in the Windows Control Panel. For versions of windows without a desktop GUI (such as Windows Server 2008 R2 Core), remove the entire Host integration tools installation. When installing on a failover cluster, you must perform the installation from an account that is a member of the domain administrator group. If you have previously installed a version of the Host Integration Tools you will see the following differences in an update installation procedure: The installer detects the previous version and notifies you that it will attempt to update the installed version to the latest version. You are prompted to deselect components (which removes those components) or select additional components for installation. If you select the EqualLogic MPIO DSM component, you are prompted to restart the computer. Performing an Unattended Installation Use the procedure described in this section to perform an unattended installation of the Host Integration Tools (that is, an installation that does not require you to monitor and respond to the installation prompts). You create a template of your installation selections as you perform an installation. You can then clone this installation template to other computers, if the other computers have: Very similar or identical hardware configurations. The same operating system and service pack level. The same system configuration for all optionally-installed features that are affected by the installation, including (but not limited to) firewall, iscsi initiator version and configuration, Microsoft MPIO. Cloning an installation works best when you are setting up a large number of identically-configured and newly-installed computers. The following considerations apply when performing an unattended installation: During the installation process, installation messages from third-party products might appear, indicating what software is being installed. However, these messages do not interfere with the installation and can be ignored. The drive letter you specify in the installation script is used on every computer on which you run the script. For example, if you specified F:\Eql in the script, all the other computers on which you run the script will attempt to install the kit on the F:\ drive. 1 11

Installation The installation applies the selections you make when you create the original recording of an installation. However, only those Host Installation Tools components that are supported by the target computer are installed. When installing on a failover clusters, you must perform the installation from an account that is a member of the domain administrator group. To perform an unattended installation: 1. Launch the windows command prompt by clicking Start, then Run. Then type cmd. 2. Start the installation script in record mode by using the following command syntax: C:\> setup.exe /r /f1"file_name.iss" Where file_name is a string specifying the full path name of the installation resource file. For example: C:\hit_install.iss. 3. Select the installation options that you want to clone to other computers. The installation procedure saves these options to the.iss file. 4. Copy the.iss file to any computer on which you want to install the Host Integration Tools. 5. Run the installation script in unattended mode by using the following command: C:\> setup.exe /s /f1"file_name" Where file_name is a string specifying the full path name of the installation resource file. For example: C:\hit_install.iss. 1 12

2 Remote Setup Wizard The Remote Setup Wizard simplifies array, group, and Windows setup. Remote Setup Wizard topics include the following: Remote Setup Wizard Overview on page 2-1 Remote Setup Wizard Computer and Group Requirements on page 2-1 Using the Remote Setup Wizard to Configure Groups on page 2-2 Launching the Remote Setup Wizard on page 2-2 Initializing an Array and Creating a Group on page 2-2 Initializing an Array and Expanding a Group on page 2-7 Enabling (or Modifying) Computer Access to a Group on page 2-9 Disabling Microsoft Service Access to a Group on page 2-11 To install the Remote Setup Wizard, see Chapter 1, Installation. See the Host Integration Tools Release Notes for the latest information about the wizard. The Host Integration Tools also include the Remote Setup Command Line Interface (RSWCLI). Use the RSWCLI utility to manage PS Series groups, instead of using the Remote Setup Wizard. For details, see Chapter 3, Remote Setup Command Line Utility. Remote Setup Wizard Overview The Remote Setup Wizard simplifies PS Series group (SAN) and Windows computer setup, enabling you to perform the following tasks: Initialize a PS Series array and either create or expand a group. The wizard will also automatically set up computer access to the group, configuring the group IP address as the iscsi target discovery address and, for new groups, enabling Microsoft service (VSS or VDS) access to the group through CHAP authentication. Configure the computer to access a group. The wizard will configure the group IP address as the iscsi target discovery address and also configure Microsoft service (VSS or VDS) access to the group if CHAP authentication is being used to restrict access. You can also use the wizard to modify access information or disallow computer access to a group. Configure multipath I/O. Redundant network paths between a computer and group volumes provide highly-available and high-performance access to data. See Chapter 4, Using the Multipath I/O DSM for details about how to configure multipath I/O. Note: If you deferred setting up required services during Host Integration Tools installation, you must configure the services before you run the Remote Setup Wizard Remote Setup Wizard Computer and Group Requirements Windows computer and PS Series group requirements for using the Remote Setup Wizard are as follows: 2 1

Remote Setup Wizard Computer running a supported operating system and a supported version of the Microsoft iscsi Software Initiator. See the Release Notes for information about Remote Setup Wizard operating system support. For versions of the Windows operating system that include the iscsi Initiator as a service, make sure that the Initiator service is running. Two or more supported network interface cards (NICs) or host bus adapters (HBAs) that are at least 1 Gbps. Multipath I/O does not utilize NICs with speeds of less than 1 Gbps. If you want to create or expand a group: - Uninitialized PS Series array running the minimum supported firmware revision. The array hardware must be installed and a network cable must be attached to Ethernet Port 0. Follow the hardware installation procedure described in the setup documentation for your array model. You do not require a serial cable if you are using the Remote Setup Wizard, although you should keep the serial cable for later use in case there is no network access to the array or group. - Connection between the array and computer. There are two connection options: Connect the computer to the same Ethernet segment as the array, and make sure that Layer 2 multicasting is not blocked between the array and the computer. This is the required connection method if you want to configure computer access to a group or configure multipath I/O between the computer and a group. Use an RJ45 network cable to connect the computer to Ethernet Port 0 on the uninitialized PS Series array. Using the Remote Setup Wizard to Configure Groups Use the procedures in this section to configure groups on your PS Series array. Launching the Remote Setup Wizard After you install the Host Integration tools, you can select the option to launch the Remote Setup Wizard automatically. You can also run by clicking Start, then Programs, then EqualLogic, then Remote Setup Wizard. In the dialog box, select the task you want to perform: Initialize an array (and create or expand a group). Configure the computer to access a group, if supported by the computer. Set up multipath I/O, if supported by the computer. Initializing an Array and Creating a Group Using the Remote Setup Wizard, you can initialize a PS Series array and create a PS Series group with the array as the first member. In addition, the wizard will set up computer access to the group, configuring the group IP address as the iscsi target discovery address and enabling Microsoft service (VSS or VDS) access to the group through CHAP authentication. If the Remote Setup Wizard is interrupted while initializing an array and the operation fails, you must reset the array before running the wizard again. To reset an array: 2 2

Remote Setup Wizard 1. Connect the serial cable that was shipped with the array, between the active control module and a console terminal, or a computer running a terminal emulator. 2. Enter the reset command and wait for the reset operation to complete. 3. Disconnect the serial cable, and launch the Remote Setup Wizard from the computer where it is installed. Before you initialize an array and create a group, gather information about the array configuration and the group configuration, as described in Table 2-1 and Table 2-2. The Remote Setup Wizard will prompt you for this information. Table 2-1: Array Configuration Prompt Description Member name Unique name used to identify the array in the group. The name string must be fewer than 64 alphanumeric characters or hyphens. No other characters are permitted. The first character must be a letter or number. IP address (IPv4) Netmask Default gateway RAID policy Network address for the Ethernet 0 network interface, which must be an IPv4 address. Each member must have at least one network interface on the same subnet as the group IP address, described in Table 2-2. Combines with the IP address to identify the subnet on which the Ethernet 0 network interface resides. Network address for the device used to connect subnets and forward network traffic beyond the local network. A default gateway is used to allow the Ethernet 0 network interface to communicate outside the local network (for example, to allow access to volumes from computers outside the local network). The default gateway must be on the same subnet as the Ethernet 0 network interface. RAID policy configured on the first member of the group: RAID 10 Striping on top of multiple RAID 1 (mirrored) sets, with one or two spare disks. RAID 10 provides good performance for random writes, in addition to the highest availability. RAID 50 Striping on top of multiple RAID 5 (distributed-parity) sets, with one or two spare disks. RAID 50 provides a good balance of performance (especially for sequential writes), availability, and capacity. RAID 5 One RAID 5 set, with one spare disk. RAID 5 is similar to RAID 50, with more capacity (two additional disks) but lower availability and performance. RAID 6 Of the total number of disks installed in the array, two disks are used for parity and one disk is a spare. The remainder are data disks. RAID 6-Accelerated This has the same disk configuration as RAID 6, but is used on PS Series arrays that have a mix of HDD (hard disk drives) and SDD (solid state disk drives). If you are adding an array to an existing group, use the Group Manager GUI or CLI to set the RAID policy for the new member. Table 2-2: Group Configuration Prompt Group name Description Unique name used to identify the group. The name string must be fewer than 64 alphanumeric characters or hyphens. No other characters are permitted. The first character must be a letter or number. 2 3
