Table 2.4 Device Properties Menu Fields and Descriptions
Field Field Type
[Value] Description
SCSI ID Information Displays the device’s SCSI identifier.
Device
Identifier Information Indicates the ASCII device identifier string, as extracted from the
device’s inquiry data.
MB/Sec Information
[0/5/10/20/40/
80/160] Indicates the maximum synchronous data transfer rate of the
adapter in megabytes per second corresponding to the width and
transfer rate settings that follow.
MT/Sec Configuration
[0/5/10/20/40/
80] Indicates the maximum synchronous data transfer rate of the
adapter in megatransfers per second. Can be changed to a lower
transfer rate.
Data Width Configuration
[8/16] Displays the maximum data width of the adapter in bits. Can be
changed to narrower, if available.
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, you 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 Logical Unit Numbers (LUNs) greater
than zero for a device. LUN 0 is always queried. Use this option 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.
Disconnect Configuration
[On/Off] Indicates whether to allow a device to disconnect during SCSI
operations. Some (usually newer) devices run faster with
disconnect enabled, while some (usually older) devices run faster
with disconnect disabled.
