3.1.2 Basic managed system operation

Managed systems are physically attached to and managed by the HMC. The HMC can perform tasks that affect the entire managed system, such as powering the system on and off. You can also create partitions and profiles within each managed system. These partitions and profiles define the way you configure and operate your partitioned system.

Within your managed system, you can assign resources to create partitions. Each partition runs a specific instance of an operating system. The HMC can perform tasks on individual partitions. These tasks are similar to those you can perform on traditional, non-partitioned servers. For example, you can use the HMC to start the operating system and access the operating system console.

Because the HMC provides a virtual terminal for each partition, a terminal window can be opened for each partition. This virtual terminal can be used for software installation, system diagnostics, and system outputs. Only one instance of the terminal can be opened at a time. The managed system firmware and device drivers provide the redirection of the data to the virtual terminal.

A profile defines a configuration setup for a managed system or partition. You can then use the profiles you created to start a managed system or partition in a particular configuration.

Basic operation on the managed system cover the following tasks:

Viewing properties of the managed system

Power on/Power off the managed system

Create/Activate/Reset/Shut down partitions

Create/Back up/Delete/Initialize the managed system profile
