saconfig - spare disk different controller

I am setting up RAID 1 on a MA30 storage array with a 6420 Smart Array controller.

I have the two controllers going to the MA30.

I have configured all my RAID 1 disks.
My question is:
I want to set up a spare disk.

Do I need a spare disk per controller?
Or will the spare disk fail over to what ever disk fails, does not matter what controller it is on...

I really need to use the one disk as a backup, but it doesn't need to be RAID'd. So I want to use the other disk as spare.

From the guide

Configuring Arrays on HP Smart Array Controllers Reference Guide

section Adding spare drives

Any drive that you want to use as a spare must meet the following criteria:

It must be an unassigned drive or a spare for another array

It must be of the same type as existing drives in the array

It must have a capacity no less than that of the smallest drive in the array

For the sa6402 you can add a single spare drive to several logical drives.

Hope this helps!

Torsten.
