Recommended actions while using SnapMirror

While using SnapMirror, you can increase the efficiency of data copying by using one or more of the following recommended actions.

To optimize performance, stagger your Snapshot copy update schedules so that SnapMirror activity does not begin or end at the exact minute a snap sched command operation attempts to create a Snapshot copy.
If the SnapMirror feature is scheduled to perform Snapshot management at the same time as a snap sched activity, then the Snapshot management operations scheduled using the snap sched command might fail with syslog messages: "Skipping creation of hourly snapshot" and "Snapshot already exists."
For optimum SnapMirror volume replication performance, ensure that the SnapMirror source volume and destination volume contain disks of the same size, organized in the same RAID configuration.
- If the SnapMirror source and destination are FlexVol volumes, the RAID configurations do not make a difference.
- If the SnapMirror source and destination are qtrees, volume size and configuration do not make any difference.
