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.
