I recently discovered that some folks don't know that that you *can* control access on a per-device basis. For those using HCD, the "Working with Devices" chapter of the HCD book describes "Restricting Partition Access for Devices". Note that this is the same technique you have to use to manage subchannel limits on chpids when you have a lot of LPARs.
