Method of effective Enterprise Pool resource utilization in a clustering environment

A Hardware Management Console (HMC) is an appliance used to manage Power Systems servers also known as CEC. One HMC can control multiple Power Systems servers. It may be used to create or change virtual machines (LPARs), including dynamically altering the hardware assigned to an LPAR (add and remove) without rebooting the operating system running in the LPAR.

Power Enterprise Pools with Mobile COD delivers both flexibility and economic efficiency Multi-system infrastructure providing a highly available and flexible IT infrastructure to support users most demanding business objectives. User purchase the capacity needed and may allocate and rebalance virtual processor and memory resources within the capacity pool.

A Cluster can be created with LPARs from different CECs that are part of Enterprise Pool.

The core feature of the article is that local LPAR steals the Enterprise pools resources held by previous active CEC or from other CEC that are part of Enterprise Pool either compliantly or non-compliantly, so that it can succeed in starting the applications.

The proposed article relinquish resources of LPAR/CEC which are unusable by that LPAR/CEC as defined. The LPAR/CEC is powered off with out releasing resources and lost network/HMC connectivity.

Advantages with the proposed solution:

 This method makes sure enough resources are acquired for applications to run.  Effective utilization of Enterprise Pool resources.  Avoid application downtime due to lack of resources on local CEC.  This method ensures that critical applications will be up all the times.

The method includes the following steps:

1. In a clustering environment, cluster is formed between LPAR A...
