Notes: 1. Assigning a dedicated spare does not reserve
space on that drive. Therefore, an automatic
restore is not guaranteed if a disk fails. If a disk
does fail, you must make room on the disk for the
fail-over to complete, or you must assign a differ-
ent disk with enough room. If a dedicated spare
is assigned and a drive fails, the restore process
starts automatically if there is enough space
available on the dedicated spare.
2. You cannot assign a dedicated spare while a
task is running on the array.
3. When you assign a dedicated spare either
while creating or transforming an array, the first
drive you select to create the array is assigned
by default as the dedicated spare.
4. When you add a dedicated spare after the
array has been created, you can select which
disk to use as the spare.

Options”.
