I have encountered an issue on a 480 that I cannot fix. I am trying to delete 29 LUNs but the system will not let me, I get the pop up warning window that says the LUN is being used by something else such as a snap, mirror, RLP, etc, etc... as far as I can tell none of that is true. There are no storage groups on the system, no snaps, no clones, etc. etc. Below I have some CLI outputs for LUN 19, all the others have the same results....

Navisphere CLI>naviseccli -h x.x.x.x -user nasadmin -password nasadmin -scope 0 getagent

Navisphere CLI>naviseccli -h x.x.x.x -user nasadmin -password nasadmin -scope 0  mirror -async -setfeature -off -lun 19

Async mirror: Removing driver from lu stack failed.  This LUN is already allocated to a storage group. Check that this is the correct LUN, and if so, remove the LUN from the storage group and try again. (0x79008023)

Navisphere CLI>naviseccli -h x.x.x.x -user nasadmin -password nasadmin -scope 0  mirror -async -setfeature -off -lun 6

Async mirror: Removing driver from lu stack failed.   The shadow LU that we were attempting destroy was associated with a mirror.  Remove the mirror before attempting this operation.  (0x71528274)

As I stated above there are no storage groups or mirrors that I can see, this might be the result of a badly backed out mirrorview migration in the past.

Any ideas?

Thanks!
