Non-disruptive repair of enclosure controller components

A method is disclosed for maintaining a current operating state of an enclosure when a controller card of the enclosure is repaired and/or replaced. In one embodiment, such a method maintains, within a controller card of an enclosure, operating parameters used to establish an operating state of the enclosure. The method further offloads, from the controller card while the controller card is installed in the enclosure, the operating parameters to a location external to the controller card. Upon removal of the controller card from the enclosure, the method maintains the operating state of the enclosure using the operating parameters stored in the external location. Upon reinstalling the controller card in the enclosure, the method optionally retrieves the operating parameters from the external location and initializes the controller card with the operating parameters. A corresponding system and computer program product are also disclosed.
