 | This server was originally configured with two hardware RAID virual 
 | disks, the first was RAID 1 with two 36GB drives, and the second was 
 | RAID 5 with three 72 GB drives.
 | 
 | Just like the original PR, the first was detected and identified in the 
 | the installer volume setup as both mfid0 and mfid1.
 | 
 | In order to try and work around the problem and just get the machine up 
 | and running, I tried deleting the RAID 1 virtual disk with the intention 
 | of installing everything to the RAID 5 virtual disk, however, with the 
 | first virtual disk removed, no drives where detected at all.
 | 
 | Next I will be trying removing the physical drives original used in the 
 | RAID 1 virtual disk, and re-initializing the RAID 5 array.  I will 
 | provide an update if successful.
 | 
 | In the meantime if anybody else is aware of another work around of fix 
 | for this, I appreciate hearing about it.  If a patch comes out soon, I 
 | will be happy to provide testing, but I have a small window as this 
 | server was being implemented as an emergency replacement for another server.
 
 Upgrade the mfi driver to -stable.
