a. TST (Task Set Type)
This field specifies the type of task set defined below.
Value Description
000b Task set per logical unit for all initiators
001b Task set per initiator per logical unit
010b-111b Reserved
The IDD operates according to "000b". If other value is specified in this field, the IDD reports
a "CHECK CONDITION" status (ILLEGAL REQUEST [=5] / Invalid parameter in list [=26-
00]).
b. GLTSD (Global Logging Target Save Disable) (not supported)
This bit specifies whether or not to permit the saving treatment of peculiar logging parameter
within the IDD.
Since the IDD performs the saving treatment with itself algorithm regardless of specified value
in this bit, disregards the specification in this bit.
c. RLEC (Report Log Exception Condition) (not supported)
This bit controls operations in cases where the accumulated value log parameter reaches the
maximum value.
"1" : The IDD reports a CHECK CONDITION status (UNIT ATTENTION [=6] / Log
counter at maximum [5B-02]).
"0" : The IDD executes the command which is issued next normally.
Since the IDD does not support the reporting function of exception condition, the IDD
disregards the specification in this bit.
d. Queue algorithm qualifier
This parameter controls the execution order algorithm of a command issued together with a
SIMPLE QUEUE TAG message.
When "0" is specified in this parameter, the IDD executes commands queued from each INIT
in the order in which they were received. However, the command execution order for the
READ, READ EXTENDED and PRE-FETCH commands may be changed.
When "1" is specified in this parameter, the IDD executes queued commands by the method
selected by the IDD. At this time, the INIT must verify the correctness of the data through
appropriate commands and QUEUE TAG messages.
When “F” is specified in this parameter, the IDD prohibits to order queued commands.
