Deleting a volume removes the data in the volume and frees the space to be used by other volumes in the same pool. When a volume is deleted, it is salvageable until Volume Purge Delay times out or you manually purge the deleted volumes. During the purge delay time, the deleted volume is salvageable, but the space belonging to the deleted volume is not available to other volumes. When the purging process begins, the volume is no longer salvageable.
In UMC, click Storage > Volumes.
Search or browse the servers to list the volumes associated with them.
Select the volume, click More Options icon, and then select Delete.
NOTE:If you select multiple volumes, the More Options icon is available at the top right corner of the table.
Click CONFIRM to delete the selected volume.
The deleted volumes are available in the Deleted Volumes list on the Pools page if the selected pool contains deleted volumes in it.
