The following table describes ASMCLI commands that are available for synchronous replication volumes. Table 25. ASMCLI Commands Available for Synchronous Replication Volumes Command --create Description 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 smartcopy 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). # asmcli list smart-copy --check-status Smart Copies Source: node21 : /mnt/mnt1 /mnt/mnt2 /mnt/mnt3 Snapshot: 29-May-2017 09:46:41.702126 >> Status: Warning: Snapshot cannot be used for restore.

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 78 Auto-Snapshot Manager Command Line Interface
