I was able to run the commands but still don't see the controller in the DS manager and it has not picked up an IP.

It just keeps fighting me. I also tried a replacement controller and it acts the same way.

Hi.
The blue LED means that the device is ready to be removed from the enclosure
You could try the following by the CLI interface on controller A
1. execute the cmgrSetAltToFailed command
2. Remove controller B wait 5 minutes and then reinsert it into the chassis.
3. run the cmgrSetAltToOptimal command
4. If the ip of controller B responds, then run on controller B:
loadDebug
lemClearLockdown

I have not tried connecting directly but that's something I'll try.
The firmware is fully up to date and yes, I've fully powered down, unplugged, you name it :).
I appreciate the input.

Hi Mike,
ok. I assume you have set the system powerless and restarted it.
Found some tips to update the firmware - difficult when the controller is unresponsive.
One tip was to try to connect via the out-of-band connection which is the second port on the controller.
Did you try this?

I should also point out that when looking at DS manager, the second controller GUI is dark.
BTW, the second link you shared is something I had found and tried. It's how I recovered the first controller but cannot get the second one to come online.

Thanks for the input. I hoped this could work but it didn't. The error being that controller A cannot reach controller B. No issues on losing data, I've wiped the config and just trying to get the second controller back online.

Hi Mike,
mhhhh.... I have not used these machines for many years.
Wasn't there an option to reset/reboot the other controller when you have access to the other one?
I have found the following. It's not exactly the same, but perhaps it helps to find the the solution...

I have a DS3524 where the second controller will not come back to normal. I've no idea what happened, I think controllers got moved around but what I do know is that controller A is working fine but controller B will not pick up and IP and constantly shows LU and a blue LED.
How can I get this controller back online since I can't reach it?
