I'm using grub not grub2 I'm guessing the procedure is similar, 
currently I have several entries for the RAID UUIDs but not all:
(it was one long line, I broke it up for readability)

kernel /vmlinuz-3.2.7-1.fc16.x86_64 ro
root=UUID=70ef146a-ba51-498a-9923-8500736d4f1f
rd_MD_UUID=f7d27973:c1e3562c:c97c2b84:778f9f47
rd_MD_UUID=e36e8193:d486ae1b:d9d2d364:ba744b1a
rd_NO_LUKS rd_NO_LVM rd_NO_DM LANG=en_US.UTF-8
SYSFONT=latarcyrheb-sun16 KEYTABLE=us

This makes sense as only 3 of the 5 partitions were "healthy"  I'll 
continue with the same format for the other two and re-run "grub-install"

Thanks, for the pointer

Jeff
