IBM P5 570 manual Definitions of partitions, Managed systems, Profiles

Page 57

–When the Partition Standby power-on is completed, the operator panel on the managed system displays LPAR..., indicating that the managed system is ready for you to use the HMC to partition its resources and, possibly, activate them.

–When a partition is activated, the HMC requires you to select the boot mode of the single partition.

￿System Profile

The System Profile option powers on the system according to a predefined set of profiles. Profiles are activated in the order in which they are shown in the system profile.

￿Partition autostart

This option powers on the managed system to partition standby mode and then activates all partitions that have been designated autostart.

After the system succeeds to boot with any of these choices, the HMC can be used to manage the system, such as continuing to boot from operating system or managing the logical partitions. See 2.11.2, “Hardware Management Console” on page 44.

2.11.4 Definitions of partitions

Describing the detailed process for working with the HMC and the management tasks to create and manage a logical partition, LPAR, or dynamic LPAR is not the intention of this documentation. The following section describes the additional functionality to create partitions that use fractional elements of available system resources, Micro-Partitioning.

For better understanding of the partitioning concept, this section gives an overview of common terminology. In addition to the partitioning concept, there are two components:

￿Managed Systems

￿Profiles

Managed systems

Managed systems are physical systems that are managed by the HMC. One HMC can manage more managed systems at a time.

Profiles

A profile defines the configuration of a logical partition or managed system. There are three types of profiles that can be used to create multiple profiles for each logical partition or managed system:

￿Partition profile

–A partition profile includes the collection of resource specifications, such as processing units, memory, and I/O resources, because a logical partition is not aware of a resource until it is activated.

–A logical partition can have more than one partition profile, but at least one is a minimum requirement.

￿All resources dedicated partition profile

A partition profile that contains the entire resource list of the machine, using all physical resources working as one system.

￿System profile

–A system profile is an ordered list of partition profiles. When you activate a system profile, the managed system attempts to activate the partition profiles in the defined order.
