Manufacturing default configuration

The manufacturing default configuration is the initial single partition setup of the managed system as received from your service provider.

When your system is in the manufacturing default configuration, you can install an operating system on the managed system and use the managed system as a nonpartitioned server. In this state, you do not have to manage the system using a Hardware Management Console (HMC).

If you choose to attach an HMC to a managed system that is in the manufacturing default configuration for reasons other than partitioning (such as to activate Capacity on Demand), all of the physical hardware resources on the system are automatically assigned to the logical partition. If you add new physical hardware resources to the managed system, the resources are automatically assigned to the logical partition. However, in order to use the newly added resources, you must dynamically add the resources to the logical partition or restart the logical partition. You do not have to make any partitioning changes on the server if you do not want to do so.

However, if you use the HMC to create, delete, change, copy, or activate any logical partitions or partition profiles on the managed system, the system is then in the partition mode. You must then use the HMC to manage the managed system. If the server has at least one IBM® i logical partition, then you must also change the managed system properties on the HMC so that one of the IBM i logical partitions on the managed system is the service partition for the managed system. If a managed system is managed using an HMC, and you want to return the managed system to a nonpartitioned state or if you want to partition the managed system with the Integrated Virtualization Manager or the Virtual Partition Manager, then you must follow a special procedure to reset the server.

Managed systems that are partitioned using the Integrated Virtualization Manager are not managed with an HMC. If a managed system is managed using the Integrated Virtualization Manager, then you do not have to reset the server to return the managed system to a nonpartitioned state. Also, you do not have to reset the server if you want to switch from using the Integrated Virtualization Manager to using an HMC. To switch to using an HMC, back up the data on each logical partition, attach the HMC to the server, create the logical partitions, and restore the data to the storage assigned to each logical partition.
