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 128 TB)
the delete is being performed in background and the freed space may
not be immediately available.
