Suspending and Resuming the Automatic Recovery Actions of Resource Groups

You can temporarily suspend the automatic recovery actions of a resource group. You might need to suspend the automatic recovery of a resource group to investigate and fix a problem in the cluster. Or, you might need to perform maintenance on resource group services.

To suspend the automatic recovery actions of a resource group, you issue the clresourcegroup suspend command. To resume automatic recovery actions, issue the clresourcegroup resume command.

When you suspend the automatic recovery actions of a resource group, you also bring the resource group to a quiescent state.

A suspended resource group is not automatically restarted or failed over until you explicitly issue the command that resumes automatic recovery. Whether online or offline, suspended data services remain in their current state. You can still manually switch the resource group to a different state on specified nodes. You can also still enable or disable individual resources in the resource group.

A dependency or affinity is suspended and not enforced when you suspend the automatic recovery actions of a resource group that does one of the following:

  • Contains a resource that has a restart dependency on another resource

  • Declares a strong positive or negative affinity for another resource group

When you suspend one of these categories of resource groups, Oracle Solaris Cluster provides a warning that the dependency or affinity is suspended as well.


Note -  Setting the RG_system property does not affect your ability to suspend or resume the automatic recovery actions of a resource group. However, if you suspend a resource group for which the RG_system property is set to TRUE, a warning message is produced. The RG_system property specifies that a resource group contains critical system services. If set to TRUE, the RG_system property prevents users from inadvertently stopping, deleting, or modifying a resource group or its resources.
