Hello gabriel-d,   Do you have a DRAC Dedicated port you can try?   It looks like this could be due to an unsupported operating system. You indicate it does not occur when booting to Windows.  Dell has only validated up to ESXi 6.5 for the R320. I do understand you say you have had ESXi 6.7 working, however this is an unsupported OS and do not know what the behavior would be on this OS. Supported OS : [URL] VMware ESXi 6.5   If you roll back the U3 update does it run like it did before the update?   If you don't have one, you may look at getting a dedicated port card. If this OS has a lock on the NIC ports then giving the DRAC a dedicated port may help.   Pn#2827M - ASSY Riser Card, Server Chassis, Advanced Management Expansion Adapter , iDRAC Port Card  
Hello Everyone, I have, in my homelab, a Poweredge R320 for more than a year now and it always worked well.  Two days ago, the server rebooted suddenly with an PWR2402 error. After this reboot, the error disappeared, but the iDRAC interface was not available, neither by the webinterface nor by ping. (iDRAC 7 Express). After several tests, the iDRAC seems to be working when the server is powered off or when it starts for the first time after plugging power cords, but as soon as ESXi boots, the iDRAC interface is not responding anymore. I already tried to: - Change iDRAC IP and even put in a VLAN with only my PC and the iDRAC interface (to avoid a possible IP conflict). Same problem - Dedicate a NIC for iDRAC and another one for ESXi Mgt Network (all my VM already had a dedicated NIC). Same problem - Soft resetting iDRAC from "Racadm" utility in VMWare. - Update iDRAC and Lifecycle Controller to latest version available for my server (2.65.65). Same problem - Power off the server and unplug power cords for 1 min, while pressing the power button. iDRAC works until ESXi boots up - Boot a Windows PE on a USB stick. iDRAC works even after Windows booting. My last changes on this server was last month, but I don't think that's the cause: - Changing CPU to a E5-2470V2 - Updating ESXi 6.7 to 6.7U3, enabling SNMP on the iDRAC interface to monitor it. Do you think that a full iDRAC reset (and wiping my config) will be a solution? Have you ever heard about this problem? Do you have any ideas or recommandations? Thank you in advance for all your answers. Have a nice day.
