Fujitsu MBA3300RC Computer Drive User Manual


 
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 bi
t 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.
