Deleting a logical storage configuration

Follow these steps to delete or remove a logical storage configuration for open systems storage units. This applies to entire configurations including, ranks, arrays, volumes, and extent pools.

Recommendation: Because this procedure deletes the host and logical storage configuration from the applicable storage unit you can, prior to performing this task, export and save the current configuration so that it can be restored.

When you are deleting a logical storage configuration, individually delete the hosts and volume group.

To delete a logical configuration, perform the following steps:
  1. Delete host access to the volume groups that you want to remove. To remove the host port IDs use the subtask in Deleting host systems.
  2. Delete the volume group. To delete volume groups, you must complete the subtask in Deleting open systems volume groups.
  3. Delete the array. To delete an array, you must complete the subtask in Deleting arrays.
    Note: Any ranks that make up an extent pool, along with the volumes within the extent pool, are automatically deleted if the rank is assigned to the array when you delete the array.
  4. Delete any unassigned ranks using the subtask in Deleting ranks.
  5. Delete the extent pools, if they were not deleted by prior delete actions. To delete the extent pools for open systems volumes, you must complete the subtask in Deleting extent pools.
Verify that no logical configuration exists for the applicable storage unit.
