Take a Manual Snapshot
You may need to take an on-demand (manual) snapshot of a volume before you update software or make hardware changes on the array.
Even if you plan to take snapshots of volumes manually or use a third-party program, you can create a volume collection without schedules on those volumes for which snapshots are being manually taken. You may see a data service restart abort message if you take a snapshot around the same time that a scheduled snapshot for the volume is going to start. Check the volume collection to ensure that no snapshot is pending before you trigger a manual snapshot.
