Creating the schedule for volume sets

The schedule creation process for application-managed, remote snapshots differs only when an
application has associated volumes. Associated volumes are two or more volumes used by an
application (volume set).
For example, you may set up Exchange to use two volumes to support a StorageGroup: one for
mailbox data and one for logs. Those two volumes make a volume set.
When you create an application-managed, remote snapshot of a volume in a volume set, the CMC
recognizes that the volume is part of a volume set. SAN/iQ then prompts you to create a snapshot
and remote copy of each volume in the volume set. This creates a snapshot set and remote copy that
corresponds to the volume set. To see any associated snapshots, select a snapshot, click the Details
tab, and then view the Snapshot Set field.
For information about the requirements for application-managed snapshots, see the HP StorageWorks
P4000 SAN Solution user guide or online help.
When you first create the schedule, the system stores information about the volume set as it exists at
that time. If you remove volumes from the volume set using the application, you must update the
schedule. To update it, you only need to edit the schedule and click OK. The system automatically
updates the volume set information when you click OK. If you want to see the updated information,
you can click Verify Volume Associations, then click OK.
NOTE:
If you have a schedule to remote snapshot a volume and you add a volume to the volume set using
the application, the system cannot update the volume set information as described above. You must
delete the schedule and create a new one to reflect the current volume set.
The schedule also reflects the volume associations based on the volume you select when you create
the schedule. That volume becomes the "owning" volume. The Volume Set field of the schedule displays
(O) next to the owning volume. You should check that the field displays all of the volumes that you
want to snapshot. It is possible that the owning volume is not aware of all associated volumes. If it is
not, select a volume that is aware of all associated volumes and create the schedule there.
The procedure below assumes that you selected a volume that is part of a volume set.
1. In the navigation window, select the primary volume.
2. Click the Schedules tab.
3. Click Schedule Tasks, and then select New Schedule to Remote Snapshot a Volume.
4. Click Edit, and then select a Start At time.
5. Select a recurrence interval.
You can schedule a snapshot to occur every 30 minutes or more.
