Dell PowerVault ME4 Series Storage System Administrator’s Guide

Creating snapshots

You can create snapshots of selected virtual volumes or of virtual snapshots. You can create snapshots immediately or schedule snapshot creation.

If the large pools feature is enabled, through use of the large-pools parameter of the set advanced-settings CLI command, the maximum number of volumes in a snapshot tree is limited to 9, base volume plus 8 snapshots. The maximum number of volumes per snapshot will decrease to fewer than 9 if more than 3 replication sets are defined for volumes in the snapshot tree. If creating a snapshot will exceed the limit, you will be unable to create the snapshot unless you delete a snapshot first.

To see more information about a volume, snap pool linear storage only, or snapshot, hover the cursor over the item in the volumes table.

You can view additional snapshot information by hovering the cursor over the snapshot in the Snapshots table. Viewing volumes contains more details about the Volume Information and Snapshot Information panels that appear.
