19.3 Viewing, Salvaging, or Purging Deleted NSS Volumes in a Pool
If you delete a volume, NSS removes it from the pool. However, during a specified amount of time, called the Volume Purge Delay time, you can review and restore the volumes you have deleted. After the purge delay time elapses, NSS automatically removes volumes from the system and you can no longer access them. You can also manually purge any volumes you have deleted.
During the Purge Delay time (by default, four days after a volume is deleted), you can manually purge deleted volumes, view the volume contents, transfer files from the deleted volume to other volumes, or salvage the entire volume, if desired.
You can also change the Purge Delay time to extend or reduce the time for the automatic purging cycle. The Purge Delay time command can be changed by adding a line in the autoexec.ncf file. The default value for the Purge Delay is 345600 seconds, which is four days. Specify the time in seconds. See Section 19.2, Configuring Salvage for the NSS Volume.
The Deleted Volumes option on the Pools page opens a separate Deleted Volumes page where you can purge or salvage the deleted volumes for the pool. This option is only available if the selected pool has deleted volumes on it.
WARNING:If you delete an entire pool, all the volumes are deleted with it. You cannot restore a deleted pool or any deleted volumes in it.
