Hi Hari,  The best tool (Command) that will be helpful to you is /nas/tools/whereisfs  This will provide you the details for each (or all) file systems and the physical disks (LUN) they are on as well as the resources used.  You can still explore with the other commands using nas_disks, nas_volume, nas_slice, nas_fs etc - or explore the Volumes section under Storage in the Celerra Web Manager (provided you have advanced Celerra Manager License) - and start drill down the volume management details.  However, /nas/tools/whereisfs may be the right choice for you.  Hope this helps, Sandip
Is there a way to find out what filesystems/checkpoints are using a particular disk d20 (Lun130) from a CX  in NAS?  For now I'm using nas_fs -info -all and look for d20 to find out usage details but this command output is really big and hard to search in that. Is there a better way of doing this?  thanks in advance. Hari.
