the openboot prom can do this.  troll sunhelp.org for an obp faq.

back in the mid '90s i dual-booted a sparc5 between sunos4 and
solaris2 with 'reboot -- disk1' and 'reboot -- disk2' - each was
installed on a separate disk; args after the double-dash are passed to
the obp boot.  i've never tried it with a single disk but 'disk1:a' is
a valid syntax so i don't see why not.

i have my boot disks mirrored with disksuite, and the final
not-automatic step was to put them both in the obp boot path.

for large disks - if the blade 100 has a pci bus, one of the supported
controllers...
