Abstract

A method and system is disclosed for provisioning hardware (HW) components of logical partition (LPAR) profiles with the use of dynamic failure domain analysis data to ensure redundancy compliance for the LPAR profiles. The method and system disclosed herein provides dynamic failure boundary monitoring on managed systems for existing and running LPARs ensuring redundancy compliance.

Method and System for Provisioning Hardware Components of LPAR Profiles with Failure Domain Analysis to Ensure Redundancy Compliance

Currently, a method for generating a logical partition (LPAR) profile on the Hardware Management Console (HMC) consists of an operator managing through multiple graphical user interface (GUI) configuration windows or executing multiple commands via command line interface (CLI). While automatic scripting is used for creating LPAR profiles, there is no failure domain analysis available during provisioning of the hardware (HW) resources to ensure redundancy compliance for the LPAR profiles.

Failure domain analysis is a manual process, requiring an individual skilled in identifying failure domain boundaries. Moreover, customers with many different systems require a team of system architects to complete failure domain analysis. The team of system architects tracks the system's HW resources during allocation to LPAR profiles.

The method and system disclosed herein provides provisioning HW components of LPAR profiles with the use of dynamic failure domain analysis data to ensure redundancy compliance.

The method and system disclosed herein also provides dynamic failure boundary monitoring on managed systems for existing and running LPARs, thereby ensuring redundancy compliance. Moreover, dynamic failure domain analysis ensures redundancy compliance after HW resources are removed, repaired, replaced, or reconfigured on existing LPAR profiles.

In an exemplary implementation, the dynamic failure domain analysis is executed by HMC software (SW). Subsequently, failure domain analysis data is presented to the operator in the form of graphical display (best for manual HW provision operations) as well as in a data file (best for automated HW provision operations). Thereafter, as individual HW components are provisioned to LPAR profiles, the failure domain data is updated (dynamic failure domain analysis) by removing from the list of available HW resources the HW components which belong to the same failure domain boundary.

In an embodiment, dynamic failure domain analysis monitors redundancy compliance for LPAR profiles already created and utilizing HW resources. In the event a HW component is replaced, removed, or failed, the dynamic failure domain analysis data is updated to identify those HW components which are no longer redundancy compliant. Subsequently, operators are notified through the service interface (SFP) which updates the dynamic failure analysis graphical display as well

as the dynamic failure domain data file.
