I have the situation, that one of my ESXi Host, is sometimes nocht reachable from my vCenter. So I cannot reach the ESXi Host by ping from the vCenter. If I make a ping from my client I can reach the ESXi Host.
If I'm connected with SSH or vSphere (from my client) I can manage the Host, so I have restartet the management Network -> Did not help
- /etc/init.d/hostd restart
- /etc/init.d/vpxa restart
and I tried this
and I tried to restart the Managment Network by the DCUI
I also restarted the vCenter Server -> Did not help
I also checked the Firewall etc, but there were no changes! (the other Host at the Cluster is connected)
And I can ping the VM's which are running at the ESXi Host, which is not reachable.
Thanks for some Idea
are you running the vCenter Appliance oder are you running a Windows Server with vCenter?
- which version of vCenter / vSphere are you running?
- are all your hosts the same patch version?
-. have you checked your Management Switch Ports / Mgmt NIC(s)
check your Network/Firwall setting again. -> Port 902 / UDP
also check these
-Make sure that VLAN is configured properly for ESXi management network.
-Try swapping NIC for management port.
- If nic0 and nic1 are selected, try checking each nic by disabling other from DCUI.
