The process is similar to “Resource group offline at the primary node (ITSO_S1Node1)” on page 227. In this process, PowerHA SystemMirror tries to release all the resources that were held by the two RGs before. 

## Testing summary 

If a resource was not released because of a PowerHA SystemMirror service crash or an AIX operating system crash, PowerHA SystemMirror can do the release operation automatically after this node starts. This operation occurs before you start the PowerHA SystemMirror service by using the smitty clstart  or the clmgr start cluster  commands.
