Some devices run faster with disconnects
enabled
(mostly newer devices), while some run
faster with disconnects
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.
Since some changes only take effect after your system reboots, it is important that you quit
this Configuration utility properly. You should return to the Main Menu and exit via the
Quit
option. If you reboot the system without properly exiting the utility, some changes may
not take effect.
Device Drivers
To function properly with different SCSI devices under different operating systems you’ll
need to install
device drivers
. The device driver information should be available in your
SCSI adapter’s package.
