sync.snapmirror.arl.veto

Severity: ALERT
Description: This message occurs when a storage failover (SFO) operation is vetoed because the aggregate is hosting volumes that are in a SnapMirror® Synchronous relationship with StrictSync policy.
Corrective Action: Either convert all SnapMirror Synchronous relationships with StrictSync Policy to Sync Policy for the volumes in the aggregate and then retry the operation, or retry the operation with the "override-vetoes true" parameter. Note: Using this option can cause an I/O disruption.
Syslog Message: SnapMirror vetoed storage failover operation because aggregate "%s" is hosting volumes that are in a SnapMirror Synchronous relationship with StrictSync policy.
Parameters: aggrname (STRING): Name of the aggregate.

Severity: ERROR
Description: This message occurs when a SnapMirror® Sync relationship frequently changes status from "in-sync" to "out-of-sync". This behaviour impacts data protection. I/O restrictions are imposed on the source volume based on the mode of replication. For relationships with policy type "strict-sync-mirror", both client read AND write access are disallowed.
Corrective Action: Check network connection between the source and destination volumes. Monitor the SnapMirror® Sync relationship status by using the "snapmirror show" command and observe field "last-transfer-error" to identify the reasons for frequent status change of the SnapMirror® Sync relationship to "out-of-sync".
Syslog Message: Source volume "%s" and destination volume "%s" with relationship UUID "%s" is frequently undergoing change in status from "in-sync" to "out-of-sync".
Parameters: srcpath (STRING): Path name of the source volume of the SnapMirror relationship.
dstpath (STRING): Path name of the destination volume of the SnapMirror relationship.
relationship_id (STRING): Relationship UUID.
