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]).
