Figure 146. RELEASE (10)
The RELEASE command is used to release a LUN previously reserved. It is not an error for an Initiator to
attempt to release a reservation that is not currently active. In this case the drive returns a GOOD status.
Extents are not supported by the drive. The Ext (Extent) bit must be zero. If the Ext bit is not zero, CHECK
CONDITION status is returned with a sense key of ILLEGAL REQUEST and additional sense code of
INVALID FIELD IN CDB.
Reservation Identification is ignored.
If the 3rdPty bit is one, the drive releases the LUN, but only if the reservation was made using the
third-party reservation option and the 3rd Party ID is the ID of the Initiator that made the reservation
