The following table describes ASMCLI commands that are available for synchronous replication volumes.
Table 25. ASMCLI Commands Available for Synchronous Replication Volumes
Command Description
--create Creates a Smart Copy of a synchronous replication volume. Supports snapshots and clones only.
--mount Mounts a synchronous replication volume. Applies to active volumes and to alternate volumes after
successfully switching the roles of the pools.
--unmount Unmounts a synchronous replication volume. Applies to active volumes and to alternate volumes after
successfully switching the roles of the pools.
--delete Deletes a synchronous replication volume. Applies to active volumes and to alternate volumes after
successfully switching the roles of the pools.
--restore Restores a synchronous replication volume from a snapshot of the active volume. A --restore smart-
copy attempted from a snapshot created on the alternate volume will be denied. For multiple mount points,
all synchronous restoration volume restores in the set must be from a snapshot of the active volume.
Example: Attempting to Restore a Snapshot Created on the Alternate
Volume
The following example shows a listing of the status of all Smart Copies and an attempt to restore a snapshot that was created on the
alternate volume (SyncAlternate).

Creating and Managing Smart Copy Schedules
Schedules are predefined create smart-copy commands that can be created once and used repeatedly. Using schedules, you can:
• Name commonly used commands for creating Smart Copies to indicate their purpose (see Creating a Schedule)
• Incorporate schedules into scripts or cron jobs
