How to delete File Storage Pool on VNX5200
Hello! I am new to the support community and I am not even sure if I am listing this in the correct place. Please feel free to redirect me if this is the wrong place.
I have a customer with a unified VNX5200. Initially they wanted to run a CIFS file system on the array. They have now decided they are more comfortable running the CIFS file system from a Microsoft server as apposed to running from the DM on the VNX5200. I have already used the Disk Provisioning Wizard for File to let AVM handle all the tasks associated with the file storage pool creation. I am now trying to delete the pool that was created by AVM. You do not seem to be able to do this from within Unisphere. I have tried to use the nas_pool -delete command from the CLI but it is not working for me.
It first told me that the nas_pool -delete command had to be executed by root user. I su to root user and then I get "Error 2224: invalid operation". Any help with this would be greatly appreciated! Let me know if you need any other information.
Thanks,
Bobby

Bobby,
i saw you commented on another discussion as well. So did you actually delete the LUNs before you deleted them from datamovers ?

Yes. I first removed the LUNs from the ~filestorage Storage Group. Then I was able to delete the LUNs from within Unisphere on the LUNs create and manage page. I have figured out how to delete the disks using the nas_disk -delete command. I had to first shrink the file storage pool to get rid of the volume (v99) that was using the file storage pool. Once the volume was removed from the pool I was able to use the nas_disk -delete command. Below is what I have done from the CLI:
nas_pool -shrink clarsas_r6 -volumes v99
nas_disk -delete d8
nas_disk -delete d7
nas_pool -list
The pool no longer shows up with the nas_pool -list command but you can still see the pool within Unisphere. I fear this may be because I left off the -perm parameter when I executed the nas_disk -delete command. Any ideas how to get the storage pool to no longer show up in Unisphere? Let me know if you need any other information.
Thanks!

I assume if you use AVM to create the stroage pool then it is considered a system defined pool and as a result you can't delete the pool? Researching this further, that seems to be what the issue is.
I think the effect of not using the -perm meant that the disk were left in a raid group. Once I deleted the raid group I was able to re-provision those disks to the main pool.

So, everytime we create a pool with AVM it forever stays on the Celerra?
