Deleting a logical storage configuration

You can delete or remove a logical storage configuration for fixed block (FB) storage images. This applies to entire configurations including, ranks, arrays, volumes, and extent pools.

About this task

Recommendation: Because this procedure deletes the host and logical storage configuration from the applicable storage unit, before 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.

Complete the following steps to delete the logical storage configuration for an FB storage image.

Procedure

  1. Delete host access to the volume groups that you want to remove. See Deleting host systems.
  2. Delete the volume group. See Deleting volume groups.
  3. Delete the array. See 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. See Deleting ranks.
  5. Delete the extent pools, if they were not deleted by prior delete actions. See Deleting extent pools.

What to do next

Verify that no logical configuration exists for the applicable storage image.
