Deleting disk pool

Use the Delete option to delete a disk pool and all the virtual disks in the disk pool. When a disk pool is deleted, the physical disks that were associated with the disk pool change to the Unassigned state. This process creates more unconfigured capacity in the storage array, which you can reconfigure to meet your storage needs.

CAUTION: Possible loss of data access – Deleting a disk pool causes loss of all data on the virtual disks in the disk pool. Before performing this operation, back up the data on all the virtual disks in the disk pool, stop all input/output (I/O), and unmount any file systems on the virtual disk.
Keep these guidelines in mind before you delete a disk pool:
  • If you delete a disk pool that contains a snapshot repository virtual disk, you must delete the base virtual disk before you delete the associated snapshot virtual disk.
  • The capacity from the physical disks that were previously associated with the deleted disk pool is added to either of these nodes:
    • An existing Unconfigured Capacity node.
    • A new Unconfigured Capacity node if one did not exist previously.
  • You cannot delete a disk pool that has any of these conditions:
    • The disk pool contains a repository virtual disk, such as a snapshot group repository virtual disk, a replication repository virtual disk, or a Consistency Group member repository virtual disk. You must delete the logical component that has the associated repository virtual disk in the disk pool before you can delete the disk pool.
      NOTE: You cannot delete a repository virtual disk if the base virtual disk is in a different disk pool and you have not requested to delete that disk pool at the same time.
    • The disk pool contains a base virtual disk or a target virtual disk participating in a virtual disk copy operation with the status of In Progress.
To delete a disk pool:
  1. Select the Storage & Copy Services tab.
  2. Select one or more disk pools.
  3. From the menu bar, select Storage > Disk Pool > Delete.
    The Confirm Delete Disk Pool dialog is displayed.
  4. Type yes to confirm, and click OK.
    The Delete Disk Pool - Progress dialog is displayed while all the virtual disks in the disk pool are being deleted.
