Chapter 6: RAID configuration

Scan LUNs > 0

Allows you to scan for LUNs greater than zero for a device. LUN zero

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 zero 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, set this

item to [No] if a SCSI device with multiple LUNs exists on your system

but you do not want all of those LUNs to be available. This will limit

the scan to LUN 0 only.

Disconnect

Displays whether to allow a device to disconnect during SCSI

operations. Some (mostly newer) devices may run faster when you

enable this option, while some (mostly older) devices may run faster

when you disable this option.

SCSI Timeout

This field indicates the maximum amount of time [0 to 9999 seconds]

to wait for a SCSI operation to complete. While timeouts provide a

safeguard that allows the system to recover should an operation fail,

it is recommended that you use a value greater than zero. A value of

zero allows unlimited time for an operation to complete and could

result in the system hanging should an operation fail.

Press <Enter>, type in a value, and then press <Enter> again to set a

new timeout value.

Queue Tags

Allows you to use queue tags for a device. Currently, the BIOS does

not use queue tags. This item specifies queue tag control to higher

level device drivers.
