Administrator Guide

If the deleted folder contained volumes, the volumes are displayed in the Volumes list in the tree view.
About Restoring Deleted Volumes
Volume undelete provides an administrator with the ability to restore volumes that might have been deleted by mistake. This feature
is enabled by default. To turn it o or to turn it back on after it has been disabled, use the CLI recovery-bin volume command.
Volumes are automatically moved to the recovery bin by the rmware whenever a volume is deleted by an administrator. They remain
in the recovery bin for 1 week before they are automatically deleted by the rmware. You can also manually purge them from the
recovery bin.
When you delete a volume, the rmware automatically converts its volume type to a thin-provisioned volume. Restoring the volume
converts it back to its original type, and restores all the user data residing on that volume. If not enough space is available to restore a
volume to its original type, the volume is restored as a thin-provisioned volume.
The following types of volumes can be restored after deletion:
• Standard volumes
• Recovery volumes
• Synchronous replication (SyncRep) volumes residing in the SyncActive pool
• Thin-provisioned volumes
NOTE:
• If you delete a volume for which synchronous replication is enabled, the system will place the SyncActive volume into
the recovery bin. However, the SyncAlternate volume will be deleted outright and cannot be recovered.
• If the normal use of pool space results in a low amount of available free space, the rmware will permanently delete
volumes in the recovery bin to reclaim free space. This deletion can occur before the 1-week time limit has been
reached.
• Both snapshot space borrowing and the recovery bin make temporary use of free space in a pool. When the amount
of free space in a pool becomes low, recoverable volumes will be purged from the recovery bin before snapshots that
use borrowed space are deleted.
• Manual purge operations are displayed in the audit log. Automatic purge operations performed by the rmware are
logged in the event log.
Enable or Disable Volume Undelete
Volume undelete is enabled by default. Disabling volume undelete immediately purges all of the volumes that are preserved in the
recovery bin.
To turn o volume delete or to turn it back on after it has been disabled, use the CLI command recovery-bin. See the Dell EqualLogic
Group Manager CLI Reference Guide for more information.
Display Deleted Volumes
1. Click Volumes.
2. Click Volumes in the Volumes panel (not an individual volume name).
3. In the Activities panel, click Manage recovery bin. The Volume Recovery Bin dialog box opens.
• The recovery bin lists the number of deleted volumes that can be recovered, as well as each volume name, its original
storage pool, and size. The recovery bin also shows the date and time when the volume was deleted and the time when the
volume will automatically be purged if it has not been restored before then.
• Volumes that contain no data are not preserved in the recovery bin. When you delete a volume that has no data, it is
deleted immediately.
• Deleted volumes remain in the recovery bin for up to 1 week after deletion. If a deleted volume has not been restored after 1
week, it will be purged after the date and time shown in the Volume Recovery Bin dialog box.
