Creating a common Snapshot copy
In addition to the regularly scheduled Snapshot copy operations, you can manually create a common Snapshot copy between the volumes in the primary SnapMirror consistency group and the volumes in the secondary SnapMirror consistency group.
The SnapMirror group relationship must be in sync.
Create a common Snapshot copy:
destination::>snapmirror update -destination-path vs1_dst:/cg/cg_dst
Monitor the progress of the update:
destination::>snapmirror show -fields -newest-snapshot
