Component-level fault detection in virtualized information handling systems

摘要

Methods and systems for modular system awareness in virtualized information handling systems (IHSs) include generating, by a chassis management controller (CMC), dependency information indicating which ones of modular IHSs included in a chassis are dependent on individual shared components in the chassis. When a fault occurs at one of the shared components, the CMC may determine, using the dependency information, which particular ones of the modular IHSs are operationally dependent on the fault. The CMC may send information indicative of the fault and of the dependent modular IHSs to a virtual machine manager, which may generate a ranking of virtual machines. The virtual machine manager may use the rankings to make migration decisions for virtual machines among modular IHSs.

1. A method, comprising:
generating dependency information for a plurality of modular information handling systems included in a first modular information handling system chassis, wherein the dependency information specifies dependency between each of the modular information handling systems and components included in the first modular information handling system chassis; when a fault occurs in the first modular information handling system chassis, determining, based on the dependency information, dependent modular information handling systems for the fault, wherein a dependent modular information handling system operates in dependency to a component associated with the fault; responsive to the fault, changing an operating status of the dependent modular information handling systems from a first operating status to a second operating status; and outputting a notification of the fault, the second operating status, and respective identifiers for the dependent modular information handling systems to a virtual machine manager.
