Partition profiles that use all of the system resources

You can create partition profiles on your HMC that specify all of the resources on the managed system. If you activate a logical partition using such a partition profile, then the managed system assigns all of its resources to the logical partition.

If you add additional resources to the managed system, the managed system automatically assigns the added resources to the logical partition when the profile is activated. The profile must be activated while the server is in 'partition standby' state, because automatic restart of the logical partition does not assign newly added processor and memory resources. You do not have to change the partition profile for the managed system to assign the additional resources to the logical partition.

You cannot activate a logical partition using a partition profile that specifies all of the system resources if any other logical partition is running. However, after the logical partition is activated with all of the system resources, you can remove most processor and memory resources and all I/O resources from the logical partition using dynamic partitioning. This allows you to start other logical partitions using the resources that you remove from the logical partition. There is an implicit minimum amount of processor and memory resources that is reserved for the logical partition that uses all of the system resources, so you cannot remove all processor and memory resources from such a logical partition.
