unable to update

Btiiss,

It sounds like you're encountering a timeout issue during the firmware update process. Would you confirm the specific update it fails at? I would also try these steps to see if any resolve this issue:

First off I would check network connectivity:

Ensure that there are no network issues between the OpenManage Enterprise (OME) appliance and the Chassis Management Controller (CMC) or Management Module (MM). I see that you stated port 443 are open, but can you verify that it isn't being blocked by any firewall rules.

You can try increasing the timeout settings in OME to allow more time for the firmware update process. This can sometimes resolve issues where the update process is taking longer than expected.

Update OME and CMC/MM Firmware:

Ensure that both the OME appliance and the CMC/MM firmware are up to date. Sometimes, compatibility issues between different firmware versions can cause update failures. Check for the latest firmware versions on Dell's support site and apply any available updates.

If the issue persists, consider using a local repository for the firmware updates. This can help reduce the time taken to download and apply updates, as the files will be accessed from a local network share rather than over the internet. You can create a local repository using Dell Repository Manager (DRM) and configure OME to use this repository 1.

Review the job logs in OME for any specific error messages or codes that can provide more insight into why the update is failing. This information can be useful for further troubleshooting or when contacting Dell support.

Sometimes, restarting the OME services can help resolve communication issues. You can do this by logging into the OME appliance and restarting the relevant services.

Let me know if this helps and what you see.
