Model: p570 AIX: 5.3 HMC: Version 5, Release 2.1

I currently have 3 LPARS: production, VIO, and test. I want to create a training LPAR. I need to install AIX from the DVD in the p570. The DVD drive is attached to the internal ide interface at slot T15. The production and test LPAR's had this slot defined in their last activated profiles, but it was not set as "required". Here's what I've done to free up this resource:
On the test LPAR

1. removed the cd0, ide0, and pci1 device with rmdev -l
2. removed slot T15 from the default profile
3. restarted partition

On the production LPAR

1. removed the cd0, ide0 and pci5 device with rmdev -l
2. removed the slot T15 from the current running profile (it's not the default profile)

On the VIO LPAR

1. verified that T15 is not in the profile

On the new training LPAR

1. defined i/o slot T15, set as required. (must have to load OS)

Once I removed the devices from the production and test LPARS, I expected the i/o slot to be available. That's not the case. Do both of these LPAR's need to be restarted to actually release the i/o slot? If not, what step am I missing to release it to the new LPAR can use it?

TIA Dave
