 I'm just going through this myself. As far as I know mdadm does *not*
 support nvraid. It does support imsm, or intel raid, which I'm in the
 process of setting up on my workstation.
 
 I can't find anything in the docs regarding mdadm working with nvraid,
 you should be trying dmraid for that.
 
 If all you have is /dev/control and you are not using a dmraid supported
 kernel (genkernel requires dodmraid to find and assemble arrays) then
 execute `dmraid -ay` and check dmesg and /dev/mapper for contents.

Thanks Dan,

I'm not using genkernel at the moment.  I'll try those steps and let you
know how it goes.  The Raid array worked on the OpenSuse operating
system that I blew away to install gentoo, so I should be able to
resurrect it without wiping everything out.
