so you are completely decommissioning a server, in that case delete the masking view first and then try to remove all devices from the group (don't forget to add -unmap).
Vmax family, I am trying to remove devices from a strorage group and I get this error " The view cannot have empty storage/port group" . I am using the symaccess cmd.  Do I have to delete the masking view? How does it work if you want to remove only some devices from a SG and not all.   Thanks, RP
