42	y	540778 APM00112504461-000E CLSAS d42	2,1,3
43	y	5630803 APM00112504461-0032 CLATA d43	1,2,3
44	y	5630803 APM00112504461-0033 CLATA d44	1,2,3
45	y	5629513 APM00112504461-015F CLATA d45	1,2,3
46	y	273718 APM00112504461-0034 CLSAS d46	1,2,3
47	y	273718 APM00112504461-003B CLSAS d47	1,2,3
48	n	3145727 APM00112504461-0065 CAPAC d48	1,2,3

so now nas_disk -delete d48 -perm -unbind?

unmap the lun from ~filestorage storage group and delete the lun from storage pool and delete the storage pool ?

If you have created any tree quota or share you need to first delete the Share and then the tree quota. Once that is done you can delete the File System Created on the NAS pool. Using the nas_disk -list you can now see that the none of the disk except for the control luns will be in USE. you see a (n) under use column. Now you can delete the disk using the nas_disk command. Once deleted you can now delete the luns which were created under your Storage Pool/storage group.

1) Delete Share

2) Delete Quota/Folder

3) Delete File System

4) Using nas_disk command delete the unused disk ( Be careful and verify which are those disk which are part of 3TB)

5) Delete the Luns created under Storage pool/Disk Group from Unisphere.

do not use the unbind option. nas_disk -delete d48 -perm and then remove the lun from the storage group ~filestorage and then delete the Lun, delete the storage pool. Anand.

why not use unbind ?

anand2405 · Answer

I never used that option myself and when I looked up in the guide and this is what the option says

"The -unbind option removes the LUN from the VNX Storage group (if EMC Access Logix™ is enabled). The -unbind option permanently destroys the LUN and its contents. If this is the last LUN using a RAID group, then the RAID group will be deleted"

To be on a safer side i would like to do this manually, that was the only reason.

Anand.

ok, nothing wrong with that but i can tell you that as long as disk is listed as 'n' in InUse column it is safe to use -perm -delete -unbind
