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.
