Just an observation, but it sort of defeats the purpose

Sun could fix that, but would you really want a replacement
for BIOS?

Yes, I really would. I also have a hard time believing BIOS is
the issue. I have a 7110 sitting directly below an x4240 in one
of my racks... the 7110 has no issues reporting disks properly.
BIOS is indeed an issue. In many x86/x64 PC architecture designs,
and the current enumeration design of Solaris,
if you add controller cards, or move a controller card, after a
previous OS installation, then the controller numbers
and ordering changes on all the devices. ZFS apparently does not
care, but UFS would, since bios designates a specific
disk to boot from, and the OS would have a specific boot path
including a controller number such as
/dev/dsk/c3t4d0s0 that could change, hence no longer boot.
Getting to EFI firmware, dumping BIOS, and redesigning the Solaris
device enumeration framework would
make things a little more flexible in that type of scenario.
How does any of that affect an x4500 with onboard controllers that
can't ever be moved?
Stick a fiber channel controller card into your x4500 PCI slot, then go
back and look at your
controller numbering, even for the built-in disk controller chips. Here
is the cfgadm output
for an X4500 that I set up yesterday.
Notice that the first two controller numbers are for the fibre channel
devices, and
then notice that the disk controller numbers no longer match your
documentation,
or your blogs about suggested configuration;
