Parameter Data Format

"0": The HDD executes the command which is issued next normally.

Since the HDD does not support the reporting function of exception condition, the HDD disregards the specification in this bit.

e.DQue (disable queuing) (not supported)

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

f.QErr (queue error management)

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

Value

Description

 

 

00b

The HDD, 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 HDD, 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

 

HDD 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 HDD, 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 HDD is not supported "11b" specified in this field. If "11b" or "10b" is

 

specified in this field, the HDD reports a CHECK CONDITION status

 

(ILLEGAL REQUEST [=5] / Invalid parameter in list [=26-00]).

 

Specifying "01b" alone is possible, but the HDD would not function.

g.TAS (task aborted status) (not supported)

This bit specifies that a command that is aborted by a TASK frame should cause other INITs to be notified of TASK ABORTED status and brought to a command-aborted condition.

The HDD does not support this bit. This means that the HDD always reports "0" and ignores any value specified for this bit.
