Figure 94. Page A (Control Mode Page Parameters)
The control parameters defines parameters for several SCSI features.
!
Task Set Type
(TST) specifies the type of task set. The drive supports the value of 000b, task set per
logical unit for all initiators.
!
Queue algorithm modifier
specifies restrictions on the algorithm used for reordering commands that
are tagged with the SIMPLE message.
0h : Restricted reordering. The drive reorders the actual execution sequence of the queued
commands from each initiator such that data integrity is maintained for that initiator.
1h : Unrestricted reordering allowed. The drive may reorder the actual execution sequence of the
queued commands in any manner it selects. Any data integrity exposures related to command
sequence order are explicitly handled by the initiator through the selection of appropriate commands
and queue tag messages.
2h-7h : RESERVED.
8 : Command reordering is disabled
9-Fh : RESERVED
QErr
(Queue Error Management) specifies how the drive shall handle blocked tasks when another
task receives a CHECK CONDITION status.
0h : The drive suspends execution of queued and active commands from any Initiator which receives
a CHECK CONDITION status until pending sense data is cleared. Those commands still queued after
the drive has returned CHECK CONDITION status, continue execution in a normal manner when the
pending status is cleared.
