Deleting an EVS Disk

If an EVS disk is no longer used, you can delete the disk to release the virtual resources. After you permanently delete an EVS disk, EVS immediately destroys the metadata to ensure that data can no longer be accessed. In addition, the physical storage space of the EVS disk is reclaimed and cleared before being re-assigned. For any new disk created based on the re-assigned physical space, before data is written to the disk, EVS returns zero for all the read requests to the disk.

• The disk status is Available, Error, Expansion failed, Restoration failed, or Rollback failed.
• The disk is not locked by any service.
• The shared disk has been detached from all its servers.

• Ensure that separately created disks are detached. For details, see Detaching an EVS Disk.
• You are advised to back up data. You can create standard snapshots or use CBR to create disk backups.
