Under the CMC 4.5, we were able to reliably access CMC via the web interface for ~3 months. In January, we added externally signed certificates to the CMC (required by parent organization). We updated the CMC to 5.00 and we tried (failed) to enable user authentication through active directory.
After each change, the system seemed to work properly. After a few days, the web interface is no longer accessible (no response) and there is no error message. Physically removing the active CMC does force the CMC controller to flip, but it doesn't restore the web interface.
The only way to restore the web interface is to SSH to the CMC and executing the command "RACRESET SOFT". Upon reset, the web interface works fine.
After another day or two, the web interface stops responding again.
The upgrade to 5.0.1 helped on one chassis, but it still happens once a week on the other.
I thought the issue might be tied to attempted failed logons, but it is not that consistent.
In the hardware and CMC log, I can't find anything clearly related to this. Started about that time, a regular series of 30 second losses in redundancy appears in the log. These might actually be the RACRESET instead of the cause.
Any assistance in how I can troubleshoot this will be greatly appreciated.
