No it's not. Not in Linux anyway. I've never tried this util with
Solaris. Probably no chance it'd work.

See above. I've been using scsiadd on linux successfully for a couple of
years now, and it's never done anything bad, despite the author's
disclaimers. I love it. I've used it for internal, external and
hotswappable devices.

I've used it in ways the author never intended, and would be horrified
to know about, like swapping out boot drives.
