Information About When to Upgrade Resources

Explain to the cluster administrator when he or she can upgrade resources to a new version of the resource type.

The conditions under which the cluster administrator can upgrade the resource type depend on the tunability of the #$upgrade_from directive for each version of the resource in the RTR file, as follows:

• Any time (ANYTIME)

• Only when the resource is unmonitored (WHEN_UNMONITORED)

• Only when the resource is offline (WHEN_OFFLINE)

• Only when the resource is disabled (WHEN_DISABLED)

• Only when the resource group is unmanaged (WHEN_UNMANAGED)
