About Schedules
You can create schedules to automatically perform volume and NAS container operations at a specic time or on a regular basis (for
example, hourly or daily). For example, you can create a schedule to create snapshots or replicas of a volume, volume collection, or
NAS container.
The following restrictions apply:
• If a volume is part of a volume collection, make sure that a schedule for the collection does not overlap a schedule for the
volume.
• You cannot use manual transfer replication with a replication schedule. Schedules apply only to network replications. Scheduled
replications do not run until any in-process manual transfer replications are complete.
• If you are creating a replication schedule, you must congure both groups to be replication partners for each other.
• You cannot schedule a snapshot or replication operation for a template volume.
Using a schedule can generate many snapshots or replicas, so make sure that you have sucient snapshot or replication space. You
can set a limit on the number of snapshots or replicas that a schedule creates.
Create a Schedule
1. Click Volumes, expand Volumes, and then select the volume name.
2. In the Activities panel, click Create schedule to start the wizard.
3. In the Create schedule wizard:
a. Type the schedule name. The name can be up to 63 bytes and is case-insensitive. Fewer characters are accepted for this
eld if you type the value as a Unicode character string, which takes up a variable number of bytes, depending on the
specic character.
b. Turn on the schedule by selecting the Enable schedule checkbox. You can defer this action if required.
c. Select the type of schedule.
d. Select the frequency for the schedule, or select Reuse existing schedule to use an existing schedule as a model for the
new schedule
e. Click Next.
Depending on the schedule option that you selected in step 2d, one of the following dialog boxes opens:
• Run once opens Create Schedule – Run Once
• Hourly schedule opens Create Schedule – Hourly Schedule
• Daily schedule opens Create Schedule – Daily Schedule
• Reuse existing schedule opens Create Schedule – Select Existing Schedule
4. In the dialog box, select or type the following settings:
• When and how often the schedule runs
• Number of snapshots or replicas to keep
• Whether snapshots are read-write or read-only
If you selected the Reuse existing schedule option, you will rst need to select a schedule from the list.
5. Click Next and review the information in the summary to determine whether the schedule conguration is correct.
6. Click Finish, or click Back to make changes.
