Deleting a snapshot
When you delete a snapshot, all data uniquely associated with that snapshot is deleted and associated
space in the snap pool is freed for use. Snapshots can be deleted in any order, irrespective of the order in
which they were created.
CAUTION: Deleting a snapshot removes its mappings and deletes its data.
To delete a snapshot
1. Verify that hosts are not accessing the snapshot that you want to delete.
2. In the Configuration View panel, right-click a snapshot and select Provisioning > Delete Snapshot.
3. In the main panel, select the snapshot to delete.
4. Click Delete Snapshot(s).
5. Click OK to continue; otherwise, click Cancel. If you clicked OK, a processing dialog appears. When
the snapshot is deleted it is removed from the table and from the Configuration View panel. When
processing is complete a success dialog appears.
6. Click OK.
Resetting a snapshot
Instead of taking a new snapshot of a volume, you can replace the data in a snapshot with the current
data in the source volume. The snapshot's name and mapping settings are not changed. The snapshot
data is stored in the source volume's snap pool.
CAUTION: To avoid data corruption, before resetting a snapshot it must be unmounted from hosts.
You can reset a snapshot now or schedule the reset task.
To reset a snapshot now
1. Unmount the snapshot from hosts.
2. In the Configuration View panel, right-click a snapshot and select Provisioning > Reset Snapshot.
3. In the main panel, select Now.
4. Click Reset Snapshot. A message indicates whether the task succeeded or failed.
5. Optionally, remount the snapshot.
To schedule a reset snapshot task
1. In the Configuration View panel, right-click a snapshot and select Provisioning > Reset Snapshot.
2. In the main panel, select Scheduled.
3. Set the options:
• Start Schedule. Specify a date and a time in the future for the schedule to start running.
• Date must use the format yyyy-mm-dd.
• Time must use the format hh:mm followed by either AM, PM, or 24H (24-hour clock). For
example, 13:00 24H is the same as 1:00 PM.
• Recurrence. Specify how often the task should run. It is not recommended to set the interval to less
than two minutes.
• Time Constraint. Specify a time range within which the task should run.
• Date Constraint. Specify days when the task should run.
• End Schedule. Specify when the task should stop running.
4. Click Reset Snapshot. If the task succeeded, the schedule is saved and can be viewed in the overview
panel for the snapshot or system.
5. Make a reminder to unmount the snapshot before the scheduled task runs.
