    10 Release—17h Command Description The RELEASE command enables the initiator to release reservations on the library or library elements that were set by the RESERVE (16h) command. See the RESERVE Command Description on page 57 for more information. Only the initiator that reserved the library or its elements can release them. If another initiator attempts to release a reserved library or its elements, the library returns a RESERVATION CONFLICT status.
