Failover Recovery; Local Configuration - HP XP20000/XP24000 Administrator's Manual

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.
The P9000 Virtualization Adapter connects to an RAID Manager instance and requests replicated
Continuous Access S-VOLs on the recovery array.
The P9000 Virtualization Adapter looks for and checks that Continuous Access S-VOLs are members
of data replication groups, and then executes horctakeover to make them read and write S-
VOLs.
The P9000 Virtualization Adapter provides information and performs failover operations defined
in SRM failover recovery plans, and returns the following information:
Replicated key and Continuous Access S-VOLs and IDs: LDEV number and LUN WWN
CT group IDs for replicated LUNs
NOTE:
CT Group IDs for replicated LUNs are supported in 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.

Local configuration

Figure 1 shows the local configuration for the P9000 Virtualization Adapter on a Windows machine.
The Virtual Center server (VIC), SRM, and P9000 Virtualization Adapter are configured on Windows
2003.
