    1 Overview of HP StorageWorks XP Virtualization Adapter HP StorageWorks XP Virtualization Adapter (XP Virtualization Adapter) is a Perl interface between VMware Site Recovery Manager (SRM) and HP StorageWorks Disk Arrays. The interface enables SRM to provide automatic access to remote data copies when virtual machines become unavailable locally.

  • Page 7: Failover Recovery

    Adapter to unpresent and delete the point-in-time copies. XP Business Copy or XP Snapshot is used to create point-in-time copies during recovery plan testing. NOTE: For Failover, the ESX LVM settings must be set to default for point-in-time copies (default is disallow) and resignature (default is allow).

  • Page 8: Xp Virtualization Adapter Local Configuration

    NOTE: CT Group Ids for Replicated LUNs are supported in XP Business Copy SRM maps LUNs with datastores using the Replicated Keys and LUN WWN, and then moves all resources to the recovery site. NOTE: During initial setup, replicated LUNs need to be presented to both the protected and recovery ESX hosts.

  • Page 9: Xp Virtualization Adapter Configuration Using Remote Connection

    XP Virtualization Adapter is configured using the XP Virtualization Adapter command.pl (see command.pl example on page 10) as an interface adapter and the XP Virtualization Adapter command msra. In a remote connection, the XP Virtualization Adapter command.pl calls the XP Virtualization Adapter command on a remote XP RAID Manager.

    —timeout=value This option is used to specify timeout value for failover using for XP Continuous Access Journal and XP Continuous Access Asynchronous. If the timeout value is specified using the $RMSRATOV variable, then this variable is ignored. The default is 60 seconds. —testMU=value This option is used to specify MU number of the XP Business Copy or XP Snapshot volume for failover tests.
