press ENT to designate it as a hot spare.
The “Create Hot Spare” gives you the ability to define a global or dedicated hot
spare. Unlike “Global Hot Spare” which can be used with any RAID sets,
“Dedicated Hot Spare” can only be used with a specific RAID set or Enclosure.
When a disk drive fails in the RAID set or enclosure with a dedicated Hot Spare
is pre-set, data on the disk drive is rebuild automatically on the dedicated hot
spare disk.

In “Quick Volume and Raid Setup” Configuration, it collects all drives and
includes them in a RAID set. The RAID set you create is associated with exactly
one volume set, and you can modify the RAID level, stripe size, and capacity.
Designating drives as Hot Spares will also combine with RAID level in this
setup.
The volume set default settings will be:
Parameter Setting
Volume Name Volume Set # 00
SAS Port#/LUN Base/LUN 0/0/0
Cache Mode Write Back
Tag Queuing Yes
The default setting values can be changed after configuration is complete.
Follow the steps below to create RAID set using “Quick Volume and Raid Setup”
Configuration:
Choose “Quick Volume And Raid Setup”

RAID Level
Try to use drives of the same capacity in a specific array. If you use
drives with different capacities in an array, all the drives in the array is treated
as though they have the capacity of the smallest drive in the array.
The number of physical drives in a specific array determines
the RAID levels
that can be implemented with the array.
RAID 0 requires one or more physical drives,
RAID 1 requires at least 2 physical drives,
RAID 1+ Spare requires more than 2 physical drives,
RAID 3 requires at least 3 physical drives,
