Brand new 2950 Won't Boot

[James_Giannoules at Dell.com]

You cannot boot from a *disk* with a capacity greater than 2TB in a BIOS
environment. If this was an EFI environment (with appropriate boot
loader) it would work. The partitioning on the disk (logical LBA ranges
per partition table) are not important to this issue.

6x500GB RAID-5 == ~2.5TB (roughly, ignoring 1024 vs 1000 and metadata
area reservation)

You need to delete the RAID-5 and create a new smaller volume for
booting and use the rest for whatever.

You can slice the RAID-5 into two logical disks if you want.

6x500 GB raid 5 shouldn't be a problem.  After some google work, I'd say
that you are still looking at some grub issues.  Some things to look at,
menu.lst pointing to the right partition references, the size of the
/boot partition may be too large, and a really remote possibility is a
hardware failure (not impossible, but unlikely).  We've had some issues
with the hardware of some brand new 2950's - disk drive and power supply
on separate boxes.  You're at the beginning, you may just want to start
again.
