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

Is it add as a desired resource...Also, did you remove the parent
adapter of the other mass storage controller from which its currently
attached.

It was defined as a "desired" resource, though it is not allocated at
all currently. Still, however, I am unable to allocate it to anything
else, and am able to see it on the OS of the LPAR that should have
released it.

I probably should have said controller rather than drive; but yes, I
have the controller that holds the drive unallocated from the first
LPAR; but am unable to allocate it to the new LPAR.

Well you have them unallocated, but in the system that will release the
DVD, you must:

rmdev -dl cd0

It is an IDE device

rmdev -dl ide0

the IDE-device is mapped to a PCI-device

rmdev -dl pcix

you will get the pci-device by probing with lsdev -p

After that, a DLPAR works for me, if the slot is marked desired in the
active profile. A change from required to desired requires a
reactivation of the LPAR.

That's true if it's running AIX; but the LPAR is running Linux. The
procedure I followed has worked fine for the other 7 LPARS on the
machine, but not this one.

Thanks though. I'll keep plugging away at it.
