Cannot Connect to Esxi Host After Reboot

I am running ESXi 5.1U1. Ran a crossed a weird issue where whenever the ESXi host is rebooted I cannot ping the host. The only way to fix this is by changing the IP address to DHCP and then back to static.

Also, any VM's that are vmotioned off or to this host run into issues like missing gateway IP addresses. The vcenter appliance server wont respond to pings unless i remove the adapter and then re-add it.

Not sure if its an issue with the NIC itself or the switches these hosts are plugged into. Any ideas?

That make and model is this ESXi server? Are any other host in your environment having this issue? What type of network cards are installed?

Server is an HP proliant DL360 G7 this is the only ESXi host having issues. We also had a tech go onsite and replace the RAM on this machine. This required unplugging cables to get the case open. After RAM was installed server was powerd on and we first noticed the issue with the NIC's. This could have been going on a while ago but the server wasn't rebooted in a while and no VM's were ever vmotioned in a long time.

is the Management Network on vSwitch0, which is

vmnic5 and vmnic0 are connected correctly?

I have seen issue in the past where a ESXi host reboot but process the NIC order different that expected. What I mean in sometime I have a servcer make a PCIe NIC vmnic0 instead of the onboard.

On vSwitch0 are your NIC's team? If so, try disconnecting the cable from the PCIe NIC and reboot the host to see if it comes back ok.

What Vmware NIC driver version are your running?

Looks like our onsite tech switched the vmnic5 with vmnic6. After swaping them in the vmware configuration everything works perfectly fine again.
