this host already has LUNs presented from these two FAs ?  Can you post output 'symdev show -sid 123 008A'  (scramble your serial number).

and after that i have refreshed the vcm database using symmask -sid 49 refresh command as well..But still the host is not able to see

the Luns assigned...

dynamox · Answer

so you've completed mapping and masking ? What address did you assign on the FA, are you using dynamic lun masking ? Did you remember to run 'symmask -sid 123 refresh'
