make a clone copy if you are worried, terminate the session and expand. If something goes bad you can always perform full restore ( or rather clone it back)
Hello all,  please  suggest solution to my scenario.  here is my scenario on my vmax { thin devices}  1. i have a production lun mapped to a linux host with 100Gb which is curved by forming concatentaed meta ( it is a thin ) . now i have a request to increase this 100Gb to 175GB, since i formed concatentaed meta i know we can increase on-fly. 2. but my problem is my present  100GB lun formed from symmetrix thin devices have 19 snaps with one 1 clone where this  clone is my R1 to the remote symmetrix for R2 in other site...  we know when source device is increased we need to increase all my snaps, R1 & R2 associated with that...  so how can i  increase my snap devices, R1 & R2 devices...........    Do we need to terminate the relation between the snap devices & prduction devices by doing this are we losing all the snaps ...?   appreciate for your help guys....
