• The repository’s reserve space for reuse within the consistency group is released.
• Any member virtual disk associated with the deleted snapshot image(s) is moved to a Stopped state.
• The member snapshot virtual disks associated with the deleted snapshot image(s) is deleted.
To delete two snapshot images named all_data_1 from a consistency group, use the following
command:
delete cgSnapImage consistencyGroup="all_data_1"
To succeed, all snapshot images must be deleted or the command will fail and no snapshots will be
deleted.
Scheduling Snapshot Images
Using the enableSchedule and schedule parameters with virtual disk and consistency group
commands, you can schedule regular snapshot images to recover files or schedule regular backups. The
schedule can be set when you initially create a snapshot group or consistency group, or you can add it
later to an existing snapshot group or consistency group.
You can create a schedule that runs daily or weekly in which you select specific days of the week (Sunday
through Saturday).
An example of the set snapGroup command using the schedule parameters:
set snapGroup ["snapGroupName"] enableSchedule=(TRUE | FALSE)
schedule=(immediate | snapshotSchedule)
Valid schedule values for the schedule parameter are immediate, startDate, scheduleDay,
startTime, scheduleInterval, endDate, noEndDate, timesPerDay and timeZone.

Starting, Stopping And Resuming A Snapshot Rollback
The command line interface allows you to:
• start a rollback operation from multiple snapshot images concurrently
• stop a rollback operation
• resume a rollback operation
When rolling back, the host will have immediate access to the new-rolled-back base virtual disk, but the
existing base virtual disk will not allow the host read-write access once the rollback is initiated.
NOTE: Create a snapshot of the base virtual disk just prior to initiating the rollback to preserve the
pre-rollback base virtual disk for recovery purposes.
When you start a rollback operation for a set of snapshot images, the content of the base virtual disk
changes immediately to match the point-in-time content of the selected snapshot image virtual disk. The
base virtual disk immediately becomes available for read/write requests after the rollback operation has
successfully completed.
