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 ca pab le of receiving messages other
than the TASK 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]).
