Yeah that is the only way I could ever figure out how to tell which one was the base. The 'MetaLUN Number' value from the properties of the metalun will match the LUN ID of the base LUN.  I have tried other ways to get this info but non of the metalun cli commands have any information on which LUN was the base in component 0 that I could ever find.
Hi,  Can anyone advise how I can identify what the base LUN is in an existing meta LUN? The reason I ask is because I would like to keep the base LUNs spread evenly over all RAID groups and would like to know how many base LUNs are in each RAID/storage group.  Thanks.
How to identify base LUN?
