Users Guide

For Smart Copies, you can set a maximum frequency of one copy every 5 minutes. You can also control how many Smart Copies
that ASM/ME preserves concurrently.
After you created a schedule, you can modify its time and frequency. You cannot modify the original Smart Copy options, with
the exception of adjusting the keep count to control how many Smart Copies are retained concurrently.
When you enable the schedule, it starts at the next date and time. You can temporarily disable a schedule to modify it or prevent
the schedule from running as planned. See Disable a Schedule on page 50.
Retained Copies or Replicas
You can specify the maximum number of retained snapshots or replicas created by the schedule. Snapshots and replicas are
limited by the snapshot reserve and replica reserve configured on the PS Series group. See the Dell EqualLogic Group Manager
Administrator’s Guide for details.
Recommendations for Schedule Creation
● Schedules with a very high frequency of Smart Copy creation might have a significant impact on performance, so you should
modify the schedule accordingly.
● Dell recommends that you configure notification for schedules, although it is not required. See Notification Settings for more
information.
Constraints for Schedules
● Schedules can be created for thin clone volumes, but not for template volumes, because they are read-only.
● You can schedule either snapshot or replica Smart Copy operations. You cannot create clones by using a schedule.
Schedules in Cluster Environments
ASM/ME creates, modifies, and deletes scheduled tasks on all cluster nodes that can potentially own any of the target objects
included in the scheduled task (such as volumes or application components). If a cluster node fails or goes offline at the time of
the scheduled event, the schedule fails over to whichever node becomes the owner of the target objects.
Tasks are scheduled on all nodes by default, but fail silently on all nodes that are not the current owner of the target objects in
the cluster resources affected.
In clusters, you cannot create a schedule for the quorum disk.
Create a Schedule for Smart Copies
1. Right-click the object (application, collection, or volume) and select Configure New Schedule.
2. Specify the schedule name and the schedule frequency—One time only, daily (or more frequent, such as multiple times per
day), weekly, or monthly.
(Optional) Provide a comment about the schedule and click Next.
ASM/ME displays a different dialog box depending on what frequency you chose.
3. Specify the schedule options and click Next.
4. Depending on the schedule you are configuring, you can skip the Advanced Schedule Settings dialog box entirely, or you
can configure task start and end dates and the repeat settings.
For example, if you are configuring a weekly schedule and you want it to run every hour, specify the hourly repetition in the
Repeat Task Settings panel. Click Next.
5. Specify the type of Smart Copy for the schedule. If you create a schedule for snapshot creation, you should specify how
many snapshots to keep. You can specify a number between 0 and 64.
6. Select Run Task as System User, or run it as a specified user and provide the Windows credentials.
NOTE:
Do not run the schedule as a system user if the schedule is for objects that affect cluster resources. If you run
the task as a specified user, you must provide login credentials for the account, and the account must have appropriate
