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 drive will not return an error if the initiator
attempts to release a reservation that is not currently valid. The data format and field
descriptions are shown in Table 5-163 and Table 5-164 respectively.
