12 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 page 49 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. Releasing an unreserved library or unreserved library
elements is not an error.
