We are not the end user, and we have specific setups/configurations that we ship. This is the first time we had this problem. So to configure IDRAC port and everything is not really a option.
One thing I find strange is that sometimes when I write esxcli hardware ipmi sdr list on the server that we have trouble with, I get this error message. I tried to execute this command three times, and on the last time I got this error message.
On the other servers it looks much more healthy.
