[SunRescue] Upgrading and E450...

[BrianMcCloskeycheckinmystyle at hotmail.com]

if there is an sca connector in every drive bay, you have the secondary sca 
backplane. if it was not there, you would only be able to have drives 
installed in either the 4 bottom bays, or 12 bottom bays. the sca backplanes 
are actually broken into 3 pieces. the one shipped with the systems by sun 
by default only covers the 4 bottom bays, the other two are 8 bay backplanes 
which allow disks to be installed in the remaining 16 bays. it sounds to me 
like you have it installed already.
