When other value is specified in this parameter, the IDD reports a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid parameter in List [=26-00]).

e.QErr (queue error management)

This field controls processing of commands queued after a sense hold state is canceled when the IDD is in the sense hold state.

Value

Description

 

 

00b

The IDD, when it has been in any one of various sense hold states, then that sense

 

hold state is cleared, continues executing the commands which are queued by

 

normal methods.

01b

The IDD, when it has been in any one of various sense hold states, then that sense

 

hold state is cleared, clears the commands which are queued. At this time, the IDD

 

generates a UNIT ATTENTION condition (UNIT ATTENTION [=6] / Command

 

Cleared by Another Initiator [=2F-00]) for each of the INITs that issued the

 

commands which were cleared.

10b

Reserved

11b

The IDD, when it has been in any one of various sense hold states, then that sense

 

hold state is cleared, clears the commands which are queued by abnormal

 

terminated INIT.

 

 

The IDD is not supported "11b" specified in this field. If "11b" or "10b" is specified in this field, the IDD reports a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid parameter in list [=26-00]).

f.DQue (disable queuing)

This bit specifies whether the IDD will execute processing of tagged commands or not.

"1" : The IDD prohibits tagged queuing processing. The IDD clears queued commands and generates a UNIT ATTENTION condition (Command cleared by another initiator [=2F- 00]) for each of the INITs that issued the commands which were cleared. After that, the when a QUEUE TAG message is received, it is rejected with a MESSAGE REJECT message and executed as an untagged command.

"0" : The IDD permits tagged queuing processing.

g.RAC (Report Check) (not supported)

The IDD is not supported in this bit. Therefore, the IDD always report "0", and ignore specified value.

h.SWP (Soft Write Protect) (not supported)

This bit specifies whether or not to execute for the device server write operation to the medium.
