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 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]).
