In this failure scenario, the discovery fails at 3% with Remote Invocation Description Aggregate blade CIMC firmware version mismatch. Activate same
firmware version on both CIMC as shown in the figure below. This can occur due to the replacement motherboard or blade module having a different
firmware than the pre-existing B460 M4 server.

The Overall Status will be Discovery Failed as shown in the figure below.

The mismatched firmware can be checked from the command line (CLI) as shown below. In the
output below, the first CIMC is the master and the second is the slave.
