1. Check the managed system properties window to ensure that enough I/O slots are available to activate the partition.
2. If there are not enough I/O slots available, create a new profile or modify the existing profile with the available resources. Then activate the partition.
3. If the partition must be activated at any cost, deactivate any running partition that is using the resource and then activate the partition.
Note: If you must activate the partition and you have tried unsuccessfully to recover using the above action, edit the profile for the partition you are activating and remove all slots that are associated with the identified slot's PHB. See the PCI Adapter Placement Reference, order number SA38-0538 for information on PHB slot associations.
4. If the problem persists, contact your service provider.
