Resolution

Log in to the standby CP and run the firmwarecommit command on the Standby CP.Check if you can start the upgrade on the Standby CP using the firmwaredownload -s command.If the Standby CP is good, wait until it finishes and check the status after the upgrade finishes by using the firmwareshow command.Confirm both CPs are on the same version. If the issue still exists, try to do the following: Run the hashow command. Check that the HA is enabled, the Heartbeat is Up, and the HA State is synchronized and that they are ok.Run the hafailover command. Wait 10 minutes.Run the hashow command. Check that the HA is enabled, the Heartbeat is Up, and the HA State is synchronized.Run the hafailover command so the switch is in the same position.Run the hashow command. Check that the HA is enabled, the Heartbeat is Up, and the HA State is synchronized.Log in to the standby CP and upgrade with firmwaredownload -s command.
