Thanks to Ric Anderson, Matthew Stier, Steven Liu, Bob and sandwich 
Maker for the following answers.

The issue isn't Solaris 8, it is the IDE controller on the Ultra-5/10.
The native IDE controller has the 137GB limit, so you will be limited to 
120GB drives. If someone sold a LBA48-compliant PCI-based IDE controller 
card, with SPARC drivers, Solaris 8 would support it.
If you really need more than two 120GB drives, I have see a webpage that 
advertises a PCI-based SATA card, with SPARC drivers. Of course the list 
price is in the $350.00 range.  At these prices, I'd start thinking 
about replacing the Ultra-10 with a second hand Sun Blade 100 or 150. 
( or ebay)

Ultra 10 limits you to 120ish gb in its controller.  See
for limitations imposed by certain versions of Solaris 8.

It's 133GB  it's a 28-bit address bus on the IDE controller.  2^28 
512-byte sectors = 137,438,953,472
