The snap update_mirror command updates the LUN to a SnapMirror destination volume residing on the same or a different storage system.
Syntax for this command is:
sdcli snap update_mirror [-m MachineName] -d MountPoint
Example
sdcli snap update_mirror -d l
The preceding example updates the SnapMirror destination for the LUN mapped to the L: drive on the local host. You do not need to specify the location of the SnapMirror destination because that information was entered when mirroring was set up for the LUN.
