Only a single logical unit can operate a series of linked commands. When the IDD receives the first
command, the logical unit specified by the IDENTIFY message or the LUN field of the CDB becomes
the object of operation in a series of linked commands and the values specified in the LUN field in the
second and subsequent CDBs are disregarded.
Note:
An INIT which uses the command link function must make the ATN signal in the SELECTION phase
TRUE and notify the TARG that it is capable of receiving messages other than the
COMPLETE message. If "1" has been specified in the Link bit of the CDB without the ATN being
made TRUE by the INIT in the SELECTION phase, the IDD terminates that command abnormally by
sending a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00]).
