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 #$upgrade_from directive for each version of the resource in the RTR file, as follows:
Any time (ANYTIME)
Only when the resource is unmonitored (WHEN_UNMONITORED)
Only when the resource is offline (WHEN_OFFLINE)
Only when the resource is disabled (WHEN_DISABLED)
Only when the resource group is unmanaged (WHEN_UNMANAGED)
This example shows how the tunability of the #$upgrade_from directive affects the conditions under which the cluster administrator can upgrade a resource to a new version of a resource type.
#$upgrade_from "1.1" WHEN_OFFLINE #$upgrade_from "1.2" WHEN_OFFLINE #$upgrade_from "1.3" WHEN_OFFLINE #$upgrade_from "2.0" WHEN_UNMONITORED #$upgrade_from "2.1" ANYTIME #$upgrade_from "" WHEN_UNMANAGED
