Rebuild a RAID

I need to know how to rebuild a broken RAID.

I have a system with a netraid 4m and 6 disks
in 3 containers of 2 disks in RAID 1:
Container 1: 0 + 10
Container 2: 1 + 11
Container 3: 2 + 12

One of the disks is dead and the people in charge has taken it away.

When I tried to put the new disk in place, the container manager shows this configuration:

Container 1 is a Volume (Only disk 10)
Container 2 is RAID 1 (Disks 1 & 11)
Container 3 is RAID 1 (Disks 2 & 12)

I had replaced disk 0, formated & initialized, but it has not been detected as a mirror of Disk 10, so it has not been reconstructed.
I can't neither put it like a hot spare.

How can i put it again as a mirror (without wipping all information on the good one, since the only way I'd seen is rebuilding the container). I can't find it in ctrl-A menus.
Thank in advance. Jorge

The Dreaded 4m

Using the FAST utility, go into container view, hightlight container 1. Select reconfiguration wizard, you should have the option to add the replacement disk 0 to container 1, Choose raid level 1.

Make sure you have a matching set of 4m fw, driver and FAST utility also.
