Quiescing Resource Groups

To stop a resource group from continuously switching from one node or zone to another when a START or STOP method fails, bring it to a quiescent state. To bring a resource group to a quiescent state, you issue the clresourcegroup quiesce command.

When you quiesce a resource group, resource methods that are executing are allowed to run until they are completed. If a serious problem occurs, you might need to quiesce a resource group immediately. To do so, you specify the -k command option, which kills the following methods:

• Prenet_start

• Start

• Monitor_start

• Monitor_stop

• Stop

• Postnet_stop

The Init, Fini Boot, and Update methods are not killed when you specify this command option.

However, if you immediately quiesce a resource group by killing methods, you might leave one of its resources in an error state such as Start_failed or Stop_failed. You must clear these error states yourself.

How to Quiesce a Resource Group

1. Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

2. Quiesce the resource group.

   # clresourcegroup quiesce resource-group

How to Quiesce a Resource Group Immediately

1. Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

2. Immediately quiesce the resource group.

   # clresourcegroup quiesce -k resource-group

   The Prenet_start, Start, Monitor_start, Monitor_stop, Stop, and Postnet_stop methods that are associated with the resource group are killed immediately. The resource group is brought to a quiescent state.

   The clresourcegroup quiesce -k command blocks until the specified resource group has reached a quiescent state.
