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 create
is associated with exactly one volume set. You will only be able
to modify the default RAID level, the stripe size, and the 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 Volume Set # 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
complete. 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 recommend that you 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 1+Spare requires at least 3 physical drives.
RAID 1E requires at least 4 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.
