Hello,
For controller A check and verify if FTP is enabled.. Also, if you are upgrading a single controller that is not set to single controller mode the controller will report a degraded health status.
ERROR: System health insufficient to support firmware update. Reason: Fail At least one controller is not up.
You can set the controller to single controller mode and then do the upgrade on the A controller.
CLI # set advanced-settings single-controller enabled
Once the controller is in single controller mode you will be able to complete the upgrade.
Once you get controller A fully upgraded, try inserting controller B. Again you will have to wait at least 15 minutes for the controller to settle. You may be able to complete the firmware upgrade on both controllers in this manner.
Cheers,
Shawn
