Creating Volume Snapshots

Describes how to create snapshots of volumes using the Control System and the CLI.

You can create a snapshot manually using the Control System and the CLI, or use a schedule to automate snapshot creation.

Note: The maximum number of snapshots that you can create for each volume is 4092. Exceeding this limit raises the snapshot failure alarm with an appropriate entry in the CLDB logs.
