Remove the board from the system as soon as possible if the following error message is displayed during a DR connect sequence:
cfgadm: Hardware specific failure: connect failed: firmware operation error
The board has failed self-test, and removing the board avoids possible reconfiguration errors that can occur during the next reboot.
The failed self-test status does not allow further operations. Therefore, if you want to retry the failed operation immediately, you must first remove and then reinsert the board.
