Cluster deconfiguration checklist
To ensure complete deconfiguration of a cluster, you must systematically remove different cluster components.
|Independent disk pool requirements|
|__||If you are using switched disk pools, the tower should be switched to the node which is the SPCN owner before deconfiguring the cluster resource group. You can use Initiate Switchover (QcstInitiateSwitchOver) API or the Change Cluster Resource Group Primary (CHGCRGPRI) command to move the CRG back to the SPCN owner. If this step is not performed, you will not be able to mark the tower private for that system.|
|__||If you plan to remove a subset of an independent disk pool group or remove the last independent disk pool in the switchable devices, you must end the CRG first. Use the End Cluster Resource Group (ENDCRG) command.|
|__|| If you want delete an independent disk pool that is
participating in a cluster, it is strongly recommended that you first delete
the device cluster resource group (CRG). See Deleting a CRG for
You can also use the Remove CRG Device Entry (RMVCRGDEVE) command to remove the configuration object of the independent disk pool from the CRG.
|__||After you have removed the configuration object of the independent disk pool from the cluster switchable device, you can delete an independent disk pool.|
|__||Delete the device description for an independent disk pool by completing
