Perc 3/Di disk failure

I had a mirrored container with a single failover disk (total of three
disks). One of the disks failed but the failover did not take over. Anyway
using afacli is used

	container unmirror

to create a single volume,then I used 

	container remove failover

to remove the failover disk, then

	container create mmirror

to mirror the working disk with what was the failover disk. All this worked
fine then I removed the failed disk and reinserted it and used

	disk initialize

to initialize what was the failed disk, it's no longer marked as failed so
for the moment I would like to set it up as a failover, howevere when I try
I get

	AFA0> container set failover 0 0
	Executing: container set failover 0 (ID=0)
	Command Error: <The specified device does not have enough free space
to be used as failover space for the specified container.>

So I have 3 questions,

1 - When I set up the new mirror I used container promote to change it to a
multi level container, could this be the cause of the above error, if so can
I change it back to a single level container?

2 - Why didn't my failover disk take over when the mirror became degraded? I
had 'controller set automatic_failover' set to ENABLE

3 - Why can't I set my failover, re: the error above

Below are is my current set up and info
