Snapshot copy schedule conflicts

If SnapMirror or SnapVault is scheduled to perform Snapshot copy management at the same time as a snap sched command operation, then the Snapshot copy management operations scheduled using the snap sched command might fail with syslog messages.

The syslog messages are:
Skipping creation of hourly snapshot
Snapshot already exists
To avoid this condition, you should stagger the Snapshot copy update schedules so that SnapMirror activity does not begin or end at the exact minute a snap sched operation attempts to create a Snapshot copy. Additionally, if snap sched Snapshot copies conflict with SnapVault activity, you should use the snapvault snap sched command to configure equivalent schedules.
Note: If the scheduled creation of a Snapshot copy fails on the first attempt, Data ONTAP attempts up to two more times to create the Snapshot copy. If all three attempts fail, an error is logged.
