How about a multi command approach ?   nas_pool -info clarata_archive  pick one of the volumes in the list and then run:  nas_volume -info v204  select one disk and run:  nas_volume -info v204  and finally  nas_disk -info d20   you will see line " protection= RAID5(6+1)" ..or whatever raid config you are using.
Is there a cli command that will detail the RAID confitguration of a storage pool.  For example, XXX command for storagepool YYY.  The output would be something like.  YYY is 123456GB in size YYY is RAID 5 4+1
Command to view RAID configurations?
