Good Day !!!!

Probably the cache settings you are choosing are not supported. Check the battery status. If the battery has failed or the charge level is not high enough the controller will disable the cache.

Try reseating the cache module. Be careful, you must shutdown and power off the server, remove the P440ar, remove the battery and then reseat the cache module. Put everything back in reverse order and ensure all components are firmly inserted.

Have you been able to solve this issue?

I have a ML110Gen9 with Smart array P440 and the 96Wr Battery cell. I have the same issue where the battery is properly seen by ILO with status Good, but the Smart Array disable the cache module saying there is a cable error, exactly in the same way as in the logs posted by the op.

What could i do?

Thanks in advance
