Device Setup Menu
When you select a specific device from the Device Selection menu, your computer displays
the following Device Setup menu. The settings in this menu effect individual SCSI devices
attached to the selected host adapter. Changes made from this menu will require a system
reboot upon exit from the SCSI Configuration utility.

Sync Rate (Mega Bytes/sec) -
Defines the maximum transfer rate the host adapter attempts
to negotiate. The host adapter and a SCSI device must agree to a rate they can both handle.
Width (bits) -
Sets the maximum data width the host adapter will attempt to negotiate. The
host adapter and a SCSI device must agree to a width they can both handle. Only those host
adapters that support 16 bit data transfers will show this option as enabled.
Disconnect -
SCSI devices have the ability to disconnect from the bus during an I/O
transfer. This option tells the host adapter whether or not to allow a device to disconnect.
Some devices run faster with disconnect
enabled
(mostly newer devices), while some run
faster with disconnect
disabled
(mostly older devices).
Read Write I/O Timeout (secs) -
This option sets the time the host adapter waits for a
read, write, verify, or seek command to complete before trying the I/O transfer again. Since
this provides a safeguard allowing the system to recover if an I/O operation fails, it is
recommended that you always set the time-out to a value greater than zero (no time-out).
Scan for Device at Boot Time -
When there is a device you do not wish to make available
to the system, set this option to
No
for that device. Also, on a bus with only a few devices
attached, you can speed up boot time by changing this setting to
No
for unused SCSI IDs.
Scan for SCSI LUNs -
You can set this option to
No
if you have problems with a device
that responds to all LUNs whether they are occupied or not.
Queue Tags -
If your device driver can issue queue tags, this option allows you to enable or
disable the issuing of queue tags during I/O requests.
Format Device
- Low level format the selected device. All information on the drive will be
erased.
