3.5 Using Quick Volume /Raid Setup Con-
figuration
“Quick Volume / Raid Setup configuration” 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-1680-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 configuration 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 specific
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 specific 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 confirm.
