BIOS CONFIGURATION

3.5 Using Quick Volume /Raid Setup Con-

guration

“Quick Volume / Raid Setup conguration” collects all available

drives and includes them in a RAID set. The RAID set you created

is associated with exactly one volume set. You will only be able to

modify the default RAID level, stripe size and capacity of the new

volume set. Designating drives as hot spares is also possible in the

“Raid Level” selection option. The volume set default settings will

be:

Parameter Setting

Volume Name ARC-1882-VOL#00

SCSI Channel/SCSI ID/SCSI LUN 0/0/0

Cache Mode Write-Back

Tag Queuing Yes

The default setting values can be changed after conguration is

completed. Follow the steps below to create arrays using the “Raid

Set / Volume Set” method:

Step Action

1 Choose “Quick Volume /Raid Setup” from the main menu. The available

RAID levels with hot spare for the current volume set drive are displayed.

2 It is recommended that you use drives of the same capacity in a specic

array. If you use drives with different capacities in an array, all drives in

the RAID set will be set to the capacity of the smallest drive in the RAID

set.

The numbers of physical drives in a specic array determines which RAID

levels that can be implemented in the array.

RAID 0 requires 1 or more physical drives.

RAID 1 requires at least 2 physical drives.

RAID 10(1E) requires at least 3 physical drives.

RAID 3 requires at least 3 physical drives.

RAID 5 requires at least 3 physical drives.

RAID 3 +Spare requires at least 4 physical drives.

RAID 5 + Spare requires at least 4 physical drives.

RAID 6 requires at least 4 physical drives.

RAID 6 + Spare requires at least 5 physical drives.

Highlight the desired RAID level for the volume set and press the Enter

key to conrm.
