Hi @Htoumi,

 

It's unlikely that the CMC is causing the M620 not able to be powered on. Previously what happen before the M620 not able to be turned on? I'm not able to understand what you mean "one of the network cables drives the server is in orange", could you rephrase. 

 

You might need to look into CMC 2's logs to check if there are any logs that informed any hardware issue. 

Hello @Htoumi,

Do you have access to the CMC? Can you check the hardware logs looking for any hardware error? If there is no CMC access you can export the log using a serial connection: https://dell.to/3IAwA6o and generating the logs:  PowerEdge Server: How to generate enclosure logs for CMC/VRTX/FX2 https://dell.to/3aEnaui

This logs are what Dell support will need to check for hardware issues. However, Dell support will only check the logs if the VRTX is in warranty. If your VRTX is no longer on warranty you will need to open an out of warranty case and ask for a quote for out of warranty reparation.

Regards.

Hello DiegoLopez,

I have access to the cmc since the CMC2 works, and this is what is in the hardware logs when the VRTX is launched "see capture"

Hi Joey C,

Thank you very much for your answer.

Before the server is shut down everything works well, but when I turned on the vrtx I got the lost redundancy message, and I noticed that the M620 doesn’t want to start anymore.

When I swiped the location of the M620 with one that is below it could start but the one I put on top did not start.

Regarding the CMC LEDs, there are usually 2 blue LEDs with 2 network cables, now there is an orange LED on the mgmt console, see the capture.

 

Hello @Htoumi,

Why the CMC firmware is so outdated? I think as per your first message is 2.01. Last version is 3.20.
Is there any reasons to not update the firmware?

Please, check this article: How to update the CMC of a Dell PowerEdge VRTX - https://dell.to/3P0I8Ct

Regards.

Hello DiegoLopez,

Thanks,

Unfortunately the old IT has neglected the firmware update, currently I am trying to recover the CMC 1 to be able to do the update.

Best regards

Hello,

I wanted to ask you if the update will be able to solve the redundancy problem.

thanks.

Best regard

Hello Htoumi,

 

For the error Chassis management controller (CMC) redundancy is lost will be resolved when you can get both CMC online.

 

You may try shut down the chassis and swap CMC slots to see if the issue stays in the slot or follows the CMC.

When you do the swap I recommend a power drain to the chassis.

Shut down any running systems, power down the chassis.

Remove all power and NIC cables for five minutes, then swap CMC slots.

Reconnect everything and check results.

 

Hello Mr, @Dell -Charles R

I followed the steps you gave me :

I did a power drain to the chassis

I removed all power and network adapter cables for five minutes, then swapped the CMC slots.

After launching the VRTX the problem follows the CMC, currently I have the CMC 2 DOWN and always the concern of redundancy, see the captures.

Best regards

Hi @Htoumi,

 

It looks like the CMC card in the server is the root cause since you have swapped it. To confirm hardware faulty, you probably need to look into the CMC logs. Else, if you have a space CMC card, you can try replacing it to check on the issue.
