Dell PowerStore Configuring Volumes

Remove a volume from a volume group

You can remove a volume from an existing volume group. Removing a volume from a volume group can affect future operations on that volume and volume group.

About this task

These affected operations can include refresh, restore, and deletion operations as well as applying and deleting protection policies.

Be aware of some conditions that apply when removing volumes from volume groups:

  • The volume retains the protection policy of the volume group from which it is removed.
  • You cannot delete the volume that you removed from the volume group until all the volume group snapshots that were taken when the volume was a part of the group are either expired or deleted.
  • When you remove a volume from a volume group that has a protection policy with a replication rule, the volume retains that policy but is not compliant until the volume group is synchronized with the destination.
    • When the volume group is synchronized to the destination, the membership change is applied to the destination volume group.

  • If you remove a volume from volume group that has existing snapshots, you cannot use those volume group snapshots for refresh or restore operations.
    • If you need to restore or refresh the volume group from a snapshot that was taken before the volume was removed, you must add the volume back to the volume group.
    • Restore and refresh operations require that the volume group membership match the membership that existed when the snapshot was taken.

Steps

  1. Under Storage, select Volume groups.
  2. On the Volume Groups page, click the name of the volume group from which you want to remove the volume.
  3. Click the Members tab, and then click the check box for the name of the volume that you want to remove.
  4. Click More Actions > Remove.
