HP Application Recovery Manager software A.06.10 Administrator's guide (March 2008)

Microsoft Cluster Server
Limitations
• Instant recovery of a cluster quorum disk is not supported because the cluster
service must never lose the connection with the quorum disk, which happens
during instant recovery (when disks are unpresented).
• In the configuration where a local disk is mounted to a cluster resource disk,
instant recovery of a such disk is not supported.
Considerations
• In a Microsoft Cluster Server environment, disks are distinguished by their disk
signature. Because two disks cannot have the same signature, operating system
dynamically changes the signature once it detects the replica on the backup
system. During the instant recovery procedure, Application Recovery Manager
restores the disk signature to ensure that the recovered disk will have the same
signature as the original disk on the application system. Application Recovery
Manager will display notifications, informing you about changed signature.
Procedure
1. Shut down the application (database).
2. Start instant recovery. For instructions, see:
• “Instant recovery procedure” on page 48 (EVA)
• “Instant recovery procedure” on page 82 (XP)
3. Restart the application (database).
4. Recover the database. For detailed procedures, see the database documentation.
ZDB omnirc variables
To customize ZDB agents, you can set environment variables in the
AppRM_home\omnirc file (Windows) or /opt/omni/.omnirc file (UNIX), on
both application and backup systems. Only the agents that are started on systems
with the environment variables set are affected. For information on the omnirc file,
see the online Help index: “omnirc”. Instructions on how to set the variables are
provided in the file.
