Start a resynchronize operation
Availability: This command is available to cluster and Vserver administrators at the admin privilege level.
snapmirror resync command establishes or reestablishes a mirroring relationship between a source and a destination endpoint. The endpoints can be Vservers, volumes or non-Data ONTAP endpoints that support SnapMirror.
snapmirror resync for a SnapMirror relationship with volumes as endpoints is typically executed in the following cases:
The destination mirror is broken (that is, the destination volume is a read-write volume and no longer a data protection mirror). After the
snapmirror resynccommand completes, the destination volume is made a data protection mirror and the mirror can be manually updated or scheduled for updates.
snapmirror update command failed because the required common Snapshot copy was deleted on the source volume.
The volumes are the first and third endpoints in a cascade chain of relationships and they have a common Snapshot copy. In this case,
snapmirror resyncmight implicitly create the SnapMirror relationship between them.
