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

 

Indicates the maximum synchronous data transfer rate in

 

 

[0 / 5 / 10 / 20 / 40]

mega transfers per second.

Scan ID

 

Configuration

 

Indicates whether to scan for this SCSI identifier at boot

 

 

[Yes / No]

 

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

 

Indicates whether to scan for LUNs greater than zero for

 

 

[Yes / No]

 

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.
