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:
- 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.
- Delete the volume group. To delete volume groups, you must complete
the subtask in Deleting open systems volume groups.
- 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.
- Delete any unassigned ranks using the subtask in Deleting ranks.
- 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.
