Host Utility (HUT) Lock is a lock that Teradata ARC utility places when ARC command like ARCHIVE/RESTORE etc. are executed on database or objects with below condition apply.
1. HUT locks are associated with the currently logged-on user who entered the statement,
not with a job or transaction.
2. HUT locks are placed only on the AMPs that are participating in a Teradata ARC
3. A HUT lock that is placed for a user on an object at one level never conflicts with another
level of lock on the same object for the same user.
We can check the Hut-lock in Teradata database using the ShowLocks Console utility.
