  • Page 7: Overview Of Hp Eva Virtualization Adapter

    1 Overview of HP EVA Virtualization Adapter HP StorageWorks EVA Virtualization Adapter (HP EVA Virtualization Adapter) is installed on VMware Site Recovery Manager (SRM) servers and enables communications between SRM and HP StorageWorks Command View EVA (and HP StorageWorks Continuous Access EVA for remote replication).

  • Page 8: Disk Array Discovery Sequence

    Figure 1 Discovered Information Disk array discovery sequence The array discovery sequence is: SRM makes a request to HP EVA Virtualization Adapter for available arrays. HP EVA Virtualization Adapter connects to HP Command View EVA servers and requests array controller port information (WWN). HP EVA Virtualization Adapter returns the results to SRM.

  • Page 9: Failover Testing

    Failover testing HP EVA Virtualization Adapter provides information and performs EVA operations for nondisruptive testing of SRM failover recovery plans. SRM uses the information gathered during the discovery process to create snapshots of remote vdisks (see Figure 2). After testing verifies the vdisks snapshots can be recovered after failure of the local array (via a recovery plan), SRM uses HP StorageWorks EVA Virtualization Adapter to unpresent and delete the snapshots.

  • Page 10: Communication Path

    HP EVA Virtualization Adapter then communicates with HP Command View EVA and correlates the requested vdisks with data replication groups. The adapter fails over each data replication group associated with the LUN information provided by SRM. HP EVA Virtualization Adapter then obtains LUN presentation information for each vdisk that has failed over and returns the information to SRM.

  • Page 11: Replication Options

    Replication options SRM with HP EVA Virtualization Adapter supports HP Continuous Access EVA synchronous and asynchronous replication operations. Command View EVA Configuration Options There are two configuration options for the disaster recovery environment with SRM and HP EVA Virtualization Adapter: Single active Command View EVA server In this configuration, the Command View EVA manage- ment server manages the protected and recovery arrays actively.

  • Page 13: Configuring Srm And The Hp Eva Disk Array

    2 Configuring SRM and the HP EVA disk array This chapter summarizes the steps to set up SRM and the HP EVA disk array for use with HP EVA Virtualization Adapter. For detailed information on these steps, see the documents listed in Related documentation.

  • Page 14: Creating Vdisks For Datastores

    NOTE: Snapclones, mirrorclones, and the ability to choose different disk group for clones are not currently supported with SRM or HP EVA Virtualization Adapter. Creating vdisks for datastores Vdisks (vdisks) need to be created for virtual machine datastores. Create the vdisks on the protected HP EVA disk array, using HP StorageWorks Command View EVA or HP StorageWorks Storage System Scripting Utility (SSSU) Command Line Interface.

  • Page 15: Pairing Srm Sites

    Pairing SRM sites You should now pair the protected and recovery sites in SRM. For more information, see the VMware Site Recovery Manager Administration Guide. Configuring SRM to communicate with HP Command View When the protected and recovery SRM servers have been paired, configure SRM to use HP EVA Virtualization Adapter by configuring array managers.
  • Page 16 From the Configure Array Managers window, click Add to add connection information for the Command View EVA servers managing your EVA disk arrays. In the Add Array Manager window, enter the storage manager addresses, usernames, and passwords in the entry fields without spaces and separating each entry with a semicolon (;). For example: Storage Manager Address - address1;address2 Username - username1;username2...
  • Page 17 Select the HP EVA disk array name that is connected to protected ESX servers. NOTE: You will also need to configure the recovery site array manager using this procedure. EVA Virtualization Adapter administrator guide...

  • Page 18: Create Protection Groups

    Verify that the array managers are configured by looking for the following information in the Configure Array Managers window: Array Manager Info Local and remote array information LUN count (equals the number of replicated LUNs on each EVA) Verify the array mangers have been configured for both protected and recovery sites, and rep- licated datastores in the Review Replicated Datastores window.

  • Page 19: Create Recovery Plans

    Create recovery plans Create recovery plans on the recovery site. A recovery plan is a list of steps the SRM follows on a protected site to switch operation from the protected site to the recovery site during a disaster (or test). For more information on creating recovery plans, see the VMware Site Recovery Manager Administration Guide.

    3 Installing and removing HP EVA Virtualization Adapter This chapter explains how to install and configure HP EVA Virtualization Adapter. NOTE: You do not need to remove the previous HP EVA Virtualization Adapter when upgrading to a newer version. IMPORTANT: A successful installation depends on using compatible versions of the OS and all installed software.
  • Page 22 NOTE: HP EVA Virtualization Adapter must be installed on both the local site SRM server (protected site) and the remote site SRM server (recovery site). Download HP EVA Virtualization Adapter installation file from the HP web page (http:// www.hp.com/go/storage/vmware) and save it in a temporary folder. Browse to the temporary folder and extract HP EVA Virtualization Adapter installation files.

  • Page 23: Checking The Installation

    Click Finish to complete the installation. You will need to restart Site Recover Manager (see Restarting Site Recovery Manager. NOTE: After this step, a readme file is displayed. Restarting Site Recovery Manager Restart Site Recovery Manager by clicking Start > Settings > Control Panel. Double-click Administrative Tools.

  • Page 24: Removing Hp Eva Virtualization Adapter

    Removing HP EVA Virtualization Adapter To remove HP EVA Virtualization Adapter: In Windows, select Start > Settings > Control Panel. Double-click Add or Remove Programs. Select HP StorageWorks EVA Virtualization Adapter. Click Change/Remove. Windows removes the program. NOTE: After removing HP EVA Virtualization Adapter, restart SRM service so it can be reflect that EVA Virtualization Adapter is no longer available.

  • Page 25: Failover And Failback With Srm

    4 Failover and failback with SRM This section discusses failover and failback with SRM. It also provides a scenario as a guide for the manual process of failback. Failover Failover occurs when an SRM recovery plan is executed, and the SRM recovery plan is configured to fail over SRM protection groups that use replicated EVA vdisks as a datastore.

  • Page 26: Snapconfig Utility

    Typically, this file is not modified; however, it can be used to customize the way test snapshots are created. After installation, Snapconfig.xml can be edited in the Windows Notepad and accessed from Start->All Programs->Hewlett-Packard->StorageWorks EVA Virtualization->SRM SnapConfig Utility The parameters that can be modified using Snapconfig are RAID type and allocation policy.

    5 Troubleshooting HP EVA Virtualization Adapter NOTE: Error messages are logged to the SRM log files. The following problems and solutions are typical. HP StorageWorks EVA disk arrays do not appear in Site Recovery Manager Solutions: If HP EVA disk arrays are not appearing in Site Recovery Manager, make sure that Site Recovery Manager has been restarted (see Restarting Site Recovery Manager, page 23).
