Non-disruptive repair of enclosure controller components

A computer program product for maintaining a current operating state of an enclosure when a controller card of the enclosure is repaired and/or replaced, the computer program product comprising a computer-readable medium having computer-usable program code embodied therein, the computer-usable program code configured to perform the following when executed by at least one processor:

• maintain, within a controller card of an enclosure, operating parameters used to establish an operating state of the enclosure;
• use, by the controller card, the operating parameters to control the operating state;
• offload, 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, maintain, 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.

A system for maintaining a current operating state of an enclosure when a controller card of the enclosure is repaired and/or replaced, the system comprising:

• at least one processor;
• at least one memory device coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to:
• maintain, within a controller card of an enclosure, operating parameters used to establish an operating state of the enclosure;
• use, by the controller card, the operating parameters to control the operating state;
• offload, 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, maintain, 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.
