snapdrive snapmirror

[RATNATHURAI]

I am able to snapmirror a lun using snapdrive and able to mount this lun to a server at the destination.

I would like to know if it is possible to reverse sync this  lun from the destination to source back.

How can I achieve this? snapmirror from source to destination

sync back to source , the lun is attached to snapdrive.

Yes this is possible, the answer you seek lies within the "snapmirror resync" command. I suggestion you consult the Data Protection Online Backup and Recovery Guide for your version of DOT. You must apply the command to the source volume so as to copy the data the proper direction.
