The production machine is Solaris 10 running on a Sun v980. Do you know
of it has any issues like these?
Additionally, would I need to do any config changes when going from
linux to solaris?

The v980 has got lots of memory and a FC disk system, but I don't know
much more about controllers and disk etc. But I suspects its got at
least the same features as the disks and controller thats in the devel
machine.
