  • Page 7: Overview Of The P9000 Virtualization Adapter

    1 Overview of the P9000 Virtualization Adapter HP StorageWorks P9000 Virtualization Adapter (P9000 Virtualization Adapter) is a Perl interface between VMware Site Recovery Manager (SRM) and HP StorageWorks P9000 and XP disk arrays. The interface enables SRM to provide automatic access to remote data copies when virtual machines become unavailable locally.

  • Page 8: Failover Testing

    Model: for example, 60-03-20/FF Product: P9000_RAID Storage Port ID: Port WWN Replicated LUNs and IDs: LDEV number and LUN WWN Remote Storage Array IDs: serial number Remote LUN IDs: LDEV number NOTE: Remote S-VOL is available to the groups through RAID Manager horcm.conf, and are replicated between protected and recovery P9000 or XP disk arrays using Continuous Access and Continuous Access Journal software.

  • Page 9: Failover Recovery

    Failover recovery During recovery, SRM executes a recovery plan. When SRM reaches the Prepare Storage step in the recovery plan, it provides the LUN information needed for failover to the P9000 Virtualization Adapter. The failover sequence is: SRM makes a request to the P9000 Virtualization Adapter to do failover to replicated LUNs on a remote (recovery) array.

    RAID Manager and array configurations HORCM instances To use the P9000 Virtualization Adapter, HORCM instances X are needed on both sites (primary and secondary), but remote communications are not needed between the instances. However, if Continuous Access paired volumes are created using RAID Manager, remote communications are needed. For failover testing, HORCM instance X+1 is needed.

    Protection groups using Continuous Access Synchronous or Continuous Access Synchronous CTG If the disk pairs for a protection group are Continuous Access Synchronous, use a fence level of DATA. If the fence level of NEVER is used, the internal horctakeover command fails (horctakeover returns EX_VOLCUR).
  • Page 19 Starting HORCM as a service in Windows RAID Manager provides the svcexe.exe command and a sample script file (HORCM0_run.txt), so RAID Manager (HORCM) can be started automatically from the services. See the HP StorageWorks P9000 RAID Manager User Guide. Starting HORCM as a service in Windows 2000/2003 RAID Manager commands and the HORCMgr process normally have the same privileges.

    verbose trivia —timeout=value This option is used to specify the timeout value for failover using for Continuous Access Journal. 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 Business Copy or Snapshot volume for failover tests.

  • Page 23: Rmsratmu

    $RMSRATMU This environment variable specifies the MU number of a Business Copy or Snapshot volume for failover testing. If the MU number value is specified through the P9000 Virtualization Adapter command option [testMU=value], this variable is ignored. The default is MU number 0. The following examples specify 1 as the MU number.

  • Page 24: Environment Variables On A Unix Host

    If RAID Manager is installed to another drive, such as the E drive, use the HORCMROOT variable: setx HORCMROOT E: /m The default timeout value for failover using Continuous Access Journal or XP Continuous Access Asynchronous is 60 seconds. To can change the timeout value, use the RMSRATOV variable: setx RMSRATOV 120 /m If RAID Manager is installed on the SRM host, no more changes are required.
