Sure, default bootdevice is 3, but you can change
it on the bootrom with setenv.
Different systems identify the hds with the idnumbers
and take id1 as sd0 and id3 as sd1. But other systems
take id3 as sd0.
And if i my memory is still working, than you
can use any id up to 6, 6 is or should be reserved
for the cdrom.
But i am no sparc guru, still newbie with some
experience and also still learning the english
language ;)
