Release Element (10) Command (57h)

The RELEASE and the RESERVE commands are used for contention

resolution in multiple-initiator systems. The

RELEASE (10) command is

used to release a previously reserved logical unit. The media changer will

not return an error if the initiator attempts to release a reservation that is

not currently valid.
