not a RAID mode, but a way to assign physical drive(s) as hot
spare to be used in case of a mirror failure. When a mirror config-
ured array has a drive fail, a spare drive can be used to replace the
failed drive and rebuild the array.
NOTE: To rebuild a drive from the SPARE POOL, the size of
the physical drive in SPARE POOL must be greater than or
equal to the smallest drive in the array.
Drive(s)
There is no default setting for this field. You must select the drives
for the configured array. When this field is selected, a pop-up win-
dow will display all the available physical drives with check-
boxes.
Use the arrow navigation keys and press the Spacebar to select or
deselect the drive or drives to be part of the array. Press
when done. If you select mirror mode as the array type, you must
select two drives to be in the array. This pop-up window will
appear only when configuring RAID 0 (Stripe) and RAID 1 (Mir-
ror) arrays.
Stripe Size
Stripe size field applies to stripe mode arrays only. By default, an
array is set up with 64 KB stripes. Edit this field to change the
default stripe size. The options for the size of the Stripes are listed
in the table below.
