Modifying A Schedule; Deleting Schedules - HP P2000 Reference Manual

Modifying a schedule

To modify a schedule
1. In the Configuration View panel, right-click the system or a volume or a snapshot and select
Provisioning > Modify Schedule.
2. In the main panel, select the schedule to modify.
3. Set the options:
• Snapshot Prefix. Optionally change the default prefix to identify snapshots created by this task. The
prefix is case sensitive; cannot include a comma, double quote, or backslash; and can have a
maximum of 14 bytes. Automatically created snapshots are named prefix_sn, where n starts at 001.
• Snapshots to Retain. Select the number of snapshots to retain. When the task runs, the retention
count is compared with the number of existing snapshots:
• If the retention count has not been reached, the snapshot is created.
• If the retention count has been reached, the volume's oldest snapshot is unmapped, reset, and
renamed to the next name in the sequence.
• Start Schedule. Specify a date and a time in the future to be the first instance when the scheduled
task will run, and to be the starting point for any specified recurrence.
• Date must use the format yyyy-mm-dd.
• Time must use the format hh:mm followed by either AM, PM, or 24H (24-hour clock). For
example, 13:00 24H is the same as 1:00 PM.
• Recurrence. Specify interval at which the task should run. The default is 30 minutes for a replication
task or 1 minute for other tasks.
• For a snapshot schedule, set the interval to at least 2 minutes. For better performance if this task
will run under heavy I/O conditions or on more than three volumes, set the retention count and
the interval to similar values; for example if the retention count is 10 then set the interval to
10 minutes.
• For a volume-copy or reset-snapshot schedule, set the interval to at least 2 minutes.
• For a replication schedule, set the interval to at least 30 minutes.
• Time Constraint. Specify a time range within which the task should run.
• Date Constraint. Specify days when the task should run. Ensure that this constraint includes the Start
Schedule date.
• End Schedule. Specify when the task should stop running.
4. Click Modify Schedule.
Click Yes to continue; otherwise, click No. If you clicked Yes, a processing dialog appears. When
5.
processing is complete a success dialog appears.
6. Click OK.

Deleting schedules

If a component has a scheduled task that you no longer want to occur, you can delete the schedule. When
a component is deleted, its schedules are also deleted.
To delete task schedules
1. In the Configuration View panel, right-click the system or a volume or a snapshot and select
Provisioning > Delete Schedule.
2. In the main panel, select the schedule to remove.
3. Click Delete Schedule. A confirmation dialog appears.
4. Click Yes to continue; otherwise, click No. If you clicked Yes, a processing dialog appears. If the task
succeeds, the schedules are removed from the table and from the Configuration View panel. When
processing is complete a success dialog appears.
5. Click OK.
