Field Field Type
[Value] Description
SCSI ID Information Device’s SCSI Identifier.
Device Identifier Information Indicates the ASCII device identifier string, as extracted
from the device’s inquiry data.
Sync Rate Configuration
[0 / 5 / 10 / 20 / 40] Indicates the maximum synchronous data transfer rate in
mega transfers per second.
Mega Xfers Data Width Data Width Synch
per second = 8 bits = 16 bits Period (ns)
0 = Asynch 0 = Asynch 0 = Asynch 0 = Asynch
5 5 10 200
10 10 20 100
20 20 40 50
40 40 80 25
Data Width Configuration
[8 / 16] Maximum data width in bits.
Scan ID Configuration
[Yes / No] Indicates whether to scan for this SCSI identifier at boot
time. Utilizing this setting allows you to ignore a device.
This decreases boot time by disabling inquiry of unused
SCSI identifiers.
Set this option to No if there is a device that you do not
want to be available to the system. Also, on a bus with
only a few devices attached, the user can speed up boot
time by changing this setting to No for all unused SCSI
IDs.
Scan LUNs > 0 Configuration
[Yes / No] Indicates whether to scan for LUNs greater than zero for
a device. LUN 0 is always queried. This option should be
used if a multi-LUN device responds to unoccupied
LUNs or if it is desired to reduce the visibility of a
multi-LUN device to LUN 0 only.
Set this option to No if you have problems with a device
that responds to all LUNs whether they are occupied or
not. Also, if a SCSI device with multiple LUNs exists on
your system but you do not want all of those LUNs to be
available to the system, then set this option to No. This
will limit the scan to LUN 0.
