Aix - Logical Partitioning - Partition Profile
A partition profile is a record on the Hardware Management Console (HMC) that
specifies a possible configuration for a logical partition. When you activate a
logical partition using a partition profile, the managed system attempts to start
the logical partition using the configuration information in the partition profile.
A partition profile specifies the desired system resources for the logical partition
and the minimum and maximum amounts of system resources that the logical
partition can have. The system resources specified within a partition profile
includes processors, memory, and I/O resources.
Each logical partition on a managed system that is managed by an HMC has at
least one partition profile. If desired, you can create additional partition profiles
with different resource specifications for your logical partition. If you create
multiple partition profiles, you can designate any partition profile on the logical
partition to be the default partition profile. The HMC activates the default profile if
you do not select a specific partition profile to be activated. Only one partition
profile can be active at one time. To activate another partition profile for a logical
partition, you must shut down the logical partition before you activate the other
partition profile.
A partition profile is identified by partition ID and profile name. Partition IDs are
whole numbers used to identify each logical partition that you create on a
managed system, and profile names identify the partition profiles that you create
for each logical partition.

Aix - Logical Partitioning - HMC
Aix - Logical Partitioning - HMC
The Hardware Management Console (HMC) is a hardware appliance that you can use to configure and control one or more managed systems. You can use the HMC to create and manage logical partitions and activate Capacity Upgrade on Demand. Using service applications, the HMC communicates with managed systems to detect, consolidate, and send information to service and support for analysis.
The HMC also provides terminal and 5250 console emulation for the logical partitions on your managed system. You can connect to logical partitions from the HMC itself, or you can set up the HMC so that you can connect to logical partitions remotely through the HMC. HMC terminal and 5250 console emulation provides a dependable connection that you can use if no other terminal or console device is connected or operational. HMC terminal and 5250 console emulation is particularly useful during initial system setup, before you have configured your terminal or console of choice.
This figure illustrates the logical partitions and the server firmware on the IBM® Systems and eServer™ hardware. The server firmware is code that is stored in system flash memory on the server. The server firmware directly controls the resource allocations on the server and the communications between logical partitions on the server. The HMC connects with the server firmware and specifies how the server firmware allocates resources on the server. If you use a single HMC to manage a server, and the HMC malfunctions or become disconnected from the server firmware, then the server continues to run, but you will not be able to change the logical partition configuration of the server or manage the server. If desired, you can attach an additional HMC to act as a backup and to provide a redundant path between the server and IBM service and support.
There are two different HMC user interfaces.
• Version 7 and later of the HMC uses a web-based user interface. You can configure the HMC to allow remote connections using a supported web browser.
• Version 6 and earlier of the HMC uses a window-based user interface. You can configure the HMC to allow remote connections using the Web-based System Manager.

Aix - Partitioning Tools - Virtual Partition Manager.
The Virtual Partition Manager is a feature of i5/OS that allows you to create and manage one i5/OS logical partition and up to four Linux logical partitions on a single IBM System i5 or eServer i5 server. You can use the Virtual Partition Manager to partition any IBM System i5 or eServer i5 model that does not require a Hardware Management Console (HMC), such as a model 595.

Aix - Logical Partitioning - Managed Systems
A managed system is a single physical server and the resources that are connected to the physical server and managed by the physical server as a single
unit. Connected resources can include expansion units, towers, and drawers, and storage area network (SAN) resources that are assigned to the server.
In the above picture, you can see the logical partitions on each managed system, with the operating systems installed on the disk drives of the physical server and the connected expansion units. The HMC is connected to both managed systems simultaneously and allows you to manage both managed systems from a single
location.

AIX - Limitations of Logical partitioning
AIX - Limitations of Logical partitioning
•Processor and memory failures might result in the failure of the entire server with all of its logical partitions. (The failure of a single I/O device affects only the logical partition to which the I/O device belongs.)
• There are many concepts that we must understand to implement logical partitions successfully on server.
• Administering a consolidated system might be more difficult in some ways than administering multiple smaller systems, particularly if the resources in the consolidated system are used at a level close to their capacity. Sharing resources.

Using high-availability application software, your partitioned server can run as an integrated cluster. You can use an integrated cluster to protect your server from most unscheduled failures within a partition.

Partitioning enables separate partitions to be allocated for production and test servers, eliminating the need to purchase additional hardware and software.When testing has been completed, the resources allocated to the test partition can be returned to the production partition or elsewhere as required. As new projects are developed, they can be built and tested on the same hardware on which they will eventually be deployed.
