I dont think you’ll find it in the data mover log  server_devconfig will NOT create any new devices if the backend Clariion isn’t healthy  You need to check the Clariion health – most likely a failed over SP, trespassed LUN, ….  Rainer
Hello, hope someone can help.  I am adding new LUNs to my NS42G (5.6.51.320) from my CX4-480 (04.30.000.5.517)  I have done this proceedure before, making certain of the HLU numbering etc.  I rescan via Celerra manger to bring the new volumes in and it replies...  xError rescan failed Storage system rescan failed make sure the system is not in fialover state.  if the system is failed over, execute the restore action to bring it to OK state Msg ID 13692698625  All areas show me that data movers are status "OK" and server_2 my primary is the active via nas_server command and state "0" on both.   Any ideas on what to check or what command line options might have better success in rescanning the new storage prior to calling support?  Thanks
