<frown>  Wouldn't it be equally logical to assume "The reason
these disks are hooked to the new controller is that the ones
that were connected to the controller previously were much SMALLER?"

It really seems like this is just a bad case of someone
thinking they know more than the user.  I *might* condone that
if we were talking about PATA drives in a PC, etc.  But, one
would assume that a person babysitting a server with RAID5
wouldn't need *quite* that much hand-holding... :<

Agreed.  I think I will reconfigure the controllers to run
just as straight SCSI HBA's and skip all traces of RAID
support (since I haven't had any issues in a few years
and I *do* have everything backed up more than a few times)

I think LSI Logic only did the PERC 4mumble's.  The 3's are Adaptec.
I think I have a couple of 3ware controllers in my goody box but
I'm not sure I am motivated to go to the hassle of swapping
everything... :<
