WORM filesystem Deletion on VNX5400

Hi All,

I have a VNX5400 storage array getting decommissioned. We have migrated all shares. I am trying to cleanup shares and file pool. I am unable to delete WORM file system getting error. Looks like it has locking period. Please let me know whether I can do anything about it or just go for direct data erasure on system ?
