Delete volume

Typically, you delete volumes if the volumes were created with the wrong parameters or capacity, no longer meet storage configuration needs, or are snapshot images that are no longer needed for backup or application testing. Deleting a volume increases the free capacity in the pool or volume group. You can select one or more volumes to delete.

Before you begin

On the volumes that you plan to delete, make sure of the following:

  • All data is backed up.

  • All Input/Output (I/O) is stopped.

  • Any devices and file systems are unmounted.

About this task

You cannot delete a volume that has one of these conditions:

  • The volume is initializing.

  • The volume is reconstructing.

  • The volume is part of a volume group that contains a drive that is undergoing a copyback operation.

  • The volume is undergoing a modification operation, such as a change of segment size, unless the volume is now in Failed status.

  • The volume is holding any type of persistent reservation.

  • The volume is a source volume or a target volume in a Copy Volume that has a status of Pending, In Progress, or Failed.

Attention
Deleting a volume causes loss of all data on those volumes.
Note
When a volume exceeds a given size (currently 64TB) the delete is being performed in background and the freed space may not be immediately available.
