I have problems removing an old snapshot which shows status "busy". This is a snapshot on a backup machine. The snapmirror relationship and the source volume do not exist anymore. I try to delete the snapshot using privilige mode "diag" and option "-ignore-owners true" but it still comes up with "... has not expired or is locked. Use the "snapshot show -fields owners, expiry-time" command to view the expiry and lock status of the Snapshot copy." This command gives owner "snapmirror" and no expiry-time set. I read somewhere to re-create the snapmirror relationship but as the source volume does not exist anymore that is not possible. Is there a solution to this? Any hints are appreciated.
