I'm having some trouble getting one of my lpars on a p550 to let go of
the dvd drive so that I can use it on another lpar.

I've tried doing it dynamically, and I've even removed it from the
hardware profile, deactivated and reactivated (i.e. not just a reboot)
and it still won't let it go.

Has anybody experienced this and found a solution?

Thanks so much,
Chris
