A method of performing resource analysis on one or more cards of a computer system is described and disclosed. In an embodiment, the method includes identifying one or more affected hardware identifiers. Each affected hardware identifier corresponds to any of the cards. Configuration information of the computer system is gathered. Moreover, the configuration information is used to analyze the affected hardware identifiers to identify any affected resource of the computer system. The identification of any affected resource is independent of a system-wide hardware scan of the computer system. Furthermore, one of a plurality of severity levels is assigned to each identified affected resource based on predetermined criteria. The severity levels include a low severity level, a medium severity level, and a high severity level. Each severity level represents degree of impact to the computer system if functionality of the identified affected resource became unavailable.

Performing resource analysis on one or more cards of a computer system wherein a plurality of severity levels are assigned based on a predetermined criteria

A method is provided of managing hardware triggered hotplug operations of one or more input/output (I/O) cards of a computer system. The method comprises receiving hardware triggers, each of which relates to a hotplug operation to be carried out on an I/O card associated with a card slot, placing the hardware triggers in a queue, and processing the queue of hardware triggers. The method further comprises processing one or more of said hardware triggers. This comprises analysing a hardware trigger to determine the card slot to which said hardware trigger relates, and consulting a hotplug operation policy to determine whether hotplug operations are enabled for said card slot. If hotplug operations are not enabled for said card slot, this further comprises ignoring said hardware trigger, and if hotplug operations are enabled for said card slot, this further comprise querying said slot to determine whether it contains a card. If said card slot does not contain a card, this further comprises ignoring said hardware trigger, and if said card slot does contain a card, determining the nature of the hotplug operation of said hardware trigger. If said hotplug operation is a delete card hotplug operation or a suspend card hotplug operation, this further comprises determining whether said card is essential or non-essential to said computer system, and ignoring said delete card hotplug operation or said suspend card hotplug operation when said card is essential, and performing said delete card hotplug operation or said suspend card hotplug operation when said card is non-essential. If said hotplug operation is an add card hotplug operation or a resume card hotplug operation, this further comprises performing said add card hotplug operation or said resume card hotplug operation.
