Snapshot schedule conflicts

If either the SnapMirror or SnapVault features are 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.

The syslog messages are:

Skipping creation of hourly snapshot

and

Snapshot already exists

To avoid this condition, stagger the Snapshot 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, use the snapvault snap sched command to configure equivalent schedules.
