Thanks to the following people who all came up with the identical answer:

        Jeff Woolsey <woolsey@jlw.com>
        domahony@csc.com
        robsonk@ebrd.com
        Mark Baldwin <mark.baldwin@makesys.com>

The solution is to add the following line to /etc/system:

        set ip:mi_maxminor = 0x3ffff

and reboot the system.

This problem has in fact already been reported to Sun and has bug ID 4209076.
A good description of exactly what is happening and how to fix it can be
found in the bug report on Sunsolve. For the sake of brevity I won't
paste it here.

I should offer the disclaimer that I haven't tried this yet as I don't
want to reboot this system at the moment. I've modified /etc/system and
will wait until a more opportune moment for the reboot. I'll post an
addendum to this summary if this doesn't fix the problem.

Thanks again!

Rob
