HP StorageWorks P9000 Virtualization Adapter Administrator Guide (5697-0680, October 2010)

• 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.
Failover testing
The P9000 Virtualization Adapter provides information and performs operations for nondisruptive
testing of SRM failover recovery plans. SRM uses the information gathered during the discovery process
to create point-in-time copies of remote LUNs. After testing verifies that the point-in-time copies of the
LUNs can be recovered after failure of the local array (via a recovery plan), SRM uses the P9000
Virtualization Adapter to unpresent and delete the point-in-time copies. Business Copy or 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).
The failover testing sequence is:
• SRM makes a request to the P9000 Virtualization Adapter to do test failover to replicated LUNs
on a remote (recovery) array.
• The P9000 Virtualization Adapter connects to a RAID Manager instance and the IDs of all replicated
point-in-time copy S-VOLs on the recovery array.
• The P9000 Virtualization Adapter looks for and checks that the point-in-time copy S-VOLs are
members of data replication groups, and then makes them read and write S-VOLs.
• The P9000 Virtualization Adapter provides information and performs failover operations for
nondisruptive testing of SRM failover recovery plans, and returns the following information:
• Replicated key and point-in-time copy S-VOLs and IDs: LDEV number and LUN WWN
• CT group IDs for replicated LUNs
• SRM maps LUNs with datastores using the replicated keys and LUN WWN.
• SRM verifies that the point-in-time copy S-VOLs can be recovered after failure of the local array
(via a recovery plan). SRM uses the P9000 Virtualization Adapter to unpresent and delete the
point-in-time copies.
NOTE:
For failover testing, the point-in-time copy S-VOLs must be created as PAIR state, and must be
registered to horcm.conf as a group.
