Explanation

https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html snapmirror resync [ -n ] [ -f ] [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination Resynchronizes a broken-off destination to its former source, putting the destination in the snapmirrored state and making it ready for update transfers. The resync command must be issued on the destination node. The resync command can cause data loss on the destination. Because it is effectively making destination a replica of the source, any edits made to the destination after the break will be For formerly mirrored volumes, the resync command effectively performs a SnapRestore (see (1)) on the destination to the newest snapshot which is common to both the source and the destination. In most cases, this is the last snapshot transferred from the source to the destination, but it can be any snapshot which is on both the source and destination due to SnapMirror replication. If new data has been written to the destination since the newest common snapshot was created, that data will be lost during the resync operation.
