1. A method for maintaining a current operating state of an enclosure when a controller card of the enclosure is repaired and/or replaced, the method comprising:
maintaining, within a controller card of an enclosure, operating parameters used to establish an operating state of the enclosure;
using, by the controller card, the operating parameters to control the operating state;
offloading, from the controller card while the controller card is installed in the enclosure, the operating parameters to a location external to the controller card; and
upon removal of the controller card from the enclosure and before reinstalling the controller card or turning over control to a different controller card, maintaining, using the operating parameters stored in the external location, the operating state of the enclosure at a state that existed at a time the controller card was removed from the enclosure.
