Requirements for RAID Manager instances
When working with RAID Manager instances, be aware of the following:
• RAID Manager instances can communicate using the most reliable network (heartbeat network)
and at least one alternate network.
• Application services using HP XP Cluster Extension must use the same RAID Manager instances.
• To provide the best failover capability, RAID Manager instances should be running at all times.
HP XP Cluster Extension provides a script to start RAID Manager instances in the system boot
process.
• For rolling disaster protection, use the same RAID Manager instances to manage XP Business
Copy pairs.
For more information about the HP XP Cluster Extension dependency on RAID Manager, see the
HP XP Cluster Extension Software Administrator Guide.
Required disk array microcode and software
Failover operations depend on the installed array microcode and RAID Manager software. Host
mode and Fibre Channel port settings for CHAs vary depending on the operating system and
microcode version. For specific microcode and software versions, see the SPOCK website: Single
Point of Connectivity Knowledge (SPOCK).
