3.9.6.5 Create a Volume Group Snapshot

A volume group is a specific collection of Exascale volumes.

A volume group enables you to easily create consistent snapshots of all volumes in the group. In one operation, you can create a set of volume snapshots with point-in-time consistency, which are easily identifiable by a unique batch ID.

To create a snapshot of a volume group, use the ESCLI mkvolumegroupsnapshot command and specify the identifier of the volume group. For example:

@> mkvolumegroupsnapshot volgrp0001_8b599d1725244432a1f47407b4e9493e

You can use the lsvolumegroup command to find the identifier for each volume group.

The output from mkvolumegroupsnapshot contains a unique volume group snapshot ID that includes the timestamp of the operation. For example, 1:1c61dd0d85914da3bae34e31a37c2f16_20250624T191208.

You can use the ID to view all of the volume snapshots as a group using the lsvolumesnapshot command. For example, the following command displays information about all the volume snapshots associated with the specified volume group snapshot ID.

@> lsvolumesnapshot --filter volumeGroupSnapshot=1:1c61dd0d85914da3bae34e31a37c2f16_20250624T191208
