Using a volume as a clustered-system lock disk
ServiceGuard does not provide a method for specifying alternative links to a clustered-system lock disk.
For releases earlier than to 11.31, when you use a volume as your lock disk in an HP
9000 or HP Integrity environment, the nodes in this system cannot access the lock disk when
both of the following situations apply:
To resolve this issue and maintain redundancy, specify a different path to the lock disk for each
node in your HP 9000 or HP Integrity system by using the
FIRST_CLUSTER_LOCK_PV variable in the system configuration ASCII file.
For example, if you are configuring a two-node system:
Note: To determine
whether the paths to the lock disk are different on different servers,
you must inspect the hardware path.
