I'd frankly be shocked if suspend/resume was supported on any modern
SPARC system. To my knowledge this was a feature that more or less died
with the desktop SPARC systems. I don't think it was ever supported on
sun4v systems.

Garrett,
I tried on T5240 Sparc server, "uadmin" is supported on Solaris10 and
OpenSolaris nevada 121.
# uadmin 3 22
uadmin: Operation not supported
'uadmin 3 22' is an x86-specific call (or more specifically, it is a
"suspend-to-ram" testpoint, and this particular feature is only
available on x86).
What you want is a Sparc test point (though, I am not sure that the
T5240 will support s/r). Try the following (as root):
echo "cpr_debug/W0xff" | mdb -kw # This will setup CPR debugging
uadmin 3 7 # This will perform a suspend on Sparc and auto-restart
Pay attention to the console and /var/adm/messages output for
problems.
Good Luck!
