Abstract

The act of updating firmware on the port controller flash may be interrupted due to an external interrupt or some other event. In this situation, the firmware update process is at risk of being in such a state as to leave the adapter (specifically the port flash) in a non-working state. This invention handles the interrupt in such a way as to recover the firmware to prevent a service action.
