Hi,
we have a VSAN cluster built with 4 ESXi hosts. For some reason one of those hosts become unresponsive - 2nd time within three weeks. This means: ESXi host lost his connectivity to vCenter Server. I can't ping the ESXi host. If I connect to the management network, it looks ok but I can't do anything. No response to F12 or F2. I have to cycle power or perform a hard reset to reboot the server. Then it will boot again, initialize the VSAN disk and is back in the cluster.
I checked all server logs but nothing here why it lost his connectivity. What VMware logs can I check? Who can help? I would like to know what happened and how to avoid this.
Thanks for your answers in advance!
