Hi Mark,  welcome to the forum.  yes, you can reconfigure *if* the disks arent used yet.  You can check that with the GUI or nas_disk or /nas/tools/whereisfs  First use the GUI or  nas_disk -perm - unbind to remove them from the Celerra  Then I would suggest to not use setup_clariion, but use the Storage Provisioning Wizard instead - it allows for greater flexibiliy (like spanning DAE's) than setup_clariion.  see attached for some examples on how to use the SPW - I think there is also a video demo about it on Powerlink  Rainer P.S.: of course what you cannot change are the first 5 disks where the Clariion and Celerra OS are located - they need to stay at RAID5 4+1
Hi All, I am after help with the following.  We recently had an EMC consultant (from a Partner) configure our Celerra NS-120.  This is equipped with 15 x FC drives in disk shelf 0 (5 x vault drives + HS located in slot # 5) which left us with 9 remaining.  The 2nd disk shelf has got 15 x FC drives and a 3rd shelf has only 1 x FC drive.  We have another disk shelf that has 15 x SATA drives but I am not concerned about that (The backend is a Clariion CX4-120). During the initial configuration, Setup_Clariion was run and was configured as below:  Disk shelf 0 = 1 x R5 (4 + 1) (these are the vault drives), 1 x HS and the remaining 9 drives configured for R5 (8 + 1). Disk shelf 1 = 3 x R5 (4 + 1) Disk shelf 2 = 1 x HS (as there was nothing else we could do with this disk)  Within Celerra Manager, when creating file systems we get the option of R5-Performance (the aggregate of all the R5 4 + 1)s, and a R5-Economy (the R5 8 + 1).  We have got file systems created within the R5-Performance disks but nothing as yet from the R5-Economy.  What we would like to do and this is my question, is reconfigure the disk layout.  We would like to remove the R5 8 + 1 disks from Disk shelf 0 and insert them into Disk shelf 2, which would then give us the correct amount of disks to do 2 x R5 4 + 1, thereby giving us the ability to use R5-Performance all round.  Is this possible, i.e can we remove disks from Disk shelf 0, and is it possible to rerun Setup_Clariion to reconfigure as I have mentioned above?  I know when I run Setup_Clariion it only gives the option to reconfigure Unbound disks, so wondering if another utility is used for this?  Any feedback would be greatly appreciated.  Regards, Mark
