Chapter 5 SCSI Drive Installation 71
Using the /V Option
This option appears on the command line by default. It enables
display of a banner, version number, and SCSI bus information
during start up of the system. The command line in CONFIG.SYS
should look like this:
BASEDEV=OS2CAM.ADD /V
To disable this feature, remove this switch from the command line.
Using the /!SN Option
This option means “no synchronous”. Synchronous transfers are
typically faster than asynchronous, so this option should only be
used if synchronous transfers cause a problem with your system.
To disable synchronous operations, the command line in
CONFIG.SYS should look like this:
BASEDEV=OS2CAM.ADD /!SN
Using the /!Q Option
This option means “no queue tag support”. Queue tagging is used
by high end systems to allow more than one outstanding command
per SCSI device. To disable queue tag support, the command line
in CONFIG.SYS should look like this:
BASEDEV=OS2CAM.ADD /!Q
Using the /ET Option
This option is used to enable Embedded Targets (LUNs). LUNs
are used by high end systems, such as disk arrays, to address
certain portions of a SCSI ID. Most standard SCSI devices do not
use LUNs, and default to LUN 0. This option should be used only
for devices that use multiple embedded targets with LUNs other
than 0. To enable LUN support, the command line in
CONFIG.SYS should look like this:
BASEDEV=OS2CAM.ADD /ET
