First off, thanks to everyone that responded. Your hints led me down the correct path!
Problem in a nutshell: I was using a new drive and it did not have a Sun Disklable on it. Therefore, the Debian SPARC install did not know what type of drive it was.
Fix: I downloaded the install disk for Solaris 9 from Sun's website and burned it to CD. When my Ultra 60 was booting, I performed a Stop-A and 'boot cdrom -s' to boot it into single user mode. I then ran the format utility. I'm certainly no professional in 'format' so I won't even mislead anyone by giving them a step-by-step here. I fuddled around with format until I could get it to auto detect the drive type, format it, partition it, and save all of the tables.
Then, reboot back into Debian (this time it saw the Sun Disklable) and deleted the existing Sun partitions. Created my on partitions and viola! Now onto new roadblocks. :)
