/V
Specifies verbose mode. This parameter displays the BusLogic ADD driver version
number and the SCSI devices that are active on the SCSI bus.
/A:n
Specifies the adapter number, where n has a value of 0-5.
/!DM
Disable DASD Manager support. The OS2DASD.DMD will manage any SCSI device that
indicates it is a removable or fixed magnetic disk.
In some cases, a device supplier may provide a specific driver
written to either IBM SCSI.SYS or Adaptec ASPI interfaces. SCSI devices may be
listed in single digits as SCSI device numbers, or as pairs of numbers
indicating a SCSI device number and logical unit number. In these cases, this
parameter might be used to disable the OS/2 DASD Manager from claiming the
device.
:unitlist
List of unit identifiers with the format t for SCSI target ID or (t,l) for SCSI
target ID and SCSI logical unit number.
For example: /!DM:4,3,(2,1)
/!SM
Disable SCSI Manager support. Prevents OS2SCSI.DMD from reporting that SCSI
devices listed are available for allocation to drivers written to IBM SCSI.SYS
interfaces. SCSI devices might be listed in single digits as SCSI device
numbers, or as pairs of numbers indicating a SCSI device number and logical unit
number.
:unitlist
List of unit identifiers with the format t for SCSI target ID or (t,l) for SCSI
target ID and SCSI logical unit number.
For example: /!SM,6,4,(2,0)
/TQ
Enables tag queuing support for all or selected SCSI devices; default is
Disabled. Tag queuing is a SCSI-II feature that allows commands to a SCSI device
to be overlapped, resulting in enhanced performance. To take advantage of this
feature, both the host adapter and the SCSI device must support tagged
queuing.
:unitlist
List of unit identifiers with the format t for SCSI target ID or (t,l) for SCSI
target ID and SCSI logical unit number.
For example: /TQ,6,4,(2,0)
/BON:n
Bus-on time (microseconds) This parameter controls the maximum amount of time a
SCSI adapter may control the system bus. The default value for OS/2 is 7
microseconds. This value can be set between 2 and 15 microseconds.
If a tape drive and a diskette drive are attached to the same
controller, and disk activity appears to interfere with the operation of the
tape drive, then setting this parameter to a lower value might help resolve the
problem.
/BOFF:n
Bus-off time (microseconds) This parameter controls the minimum amount of time a
SCSI adapter will wait between requests for control of the system bus. The
default value for OS/2 is 4 microseconds. This value can be set between 1 and 64
microseconds.
If a tape drive and a diskette drive are attached to the same
controller, and disk activity appears to interfere with the operation of the
tape drive, then setting this parameter to a higher value and reducing the /BON
value might help resolve the problem.
