Yes, this is an issue with Sparc-based machines: how to wake up
suspended machines. To the best of my knowlege, there are only two
ways to wake a suspended Sparc machine:
The front panel power button.
The power button on a Sun keyboard that is attached to it.
And even power-cycling won't get it going again (though there may be
an OBP tunable that can be set to work around this - anyone else
know?).
If you are looking for testing, instead of using sys-suspend, you
might consider (as root) to do a 'uadmin 3 7' or 'uadmin 3 8' (the
first doesn't compress the corefile - I usually suggest using '3 8',
as it is good to test the compress path). In both cases, the machine
resumes immediately (x86 users can set a sleep delay, but that is a
different discussion).
Good Luck!
