Run this command:  symaccess -sid list -type Storage -detail  Look at the "view count" column.  Anything with '0' views is not in a masking view.  Hope this helps, Peter
All:  I discovered that our VMAX has a LOT of Storage Groups that are no longer part of Masking Views.  I guess the previous guys "reclaimed" space from servers and reclaimed old servers that were retired by erasing the Masking Views, but they never erased the Storage Groups.  Is there a command that will show me the Storage Groups that are NOT part of Masking Views?  I can get a list of all of my Storage Groups and then get a list of all of my Masking Views and compare them, but that's a little tedious....      Stuart
How can I list VMAX Storage Groups that are NOT used ?
