Why the esxi host cannot be connected through the local network after updated esxi from 6.5 to 6.7u2 ?

[wood_boow]

hello every! I am trapped by a very basic problem......

this week I upgrade an esxi host from 6.5 to 6.7u2 , the media was downloaded from vmware website.

I just reboot the host and installed the esxi 6.7u2. However, when everything is done, this host still cannot be accessed by the vcenter, because it cannot connected to the local network.

The host is dell r930, 4 network adapters ,all of them are selected in the network configuration, and they have connected to the switch, and the ports are trunked.

The management IP of the host is static IP. IP, netmask, netgate are configured correctly, just as the same before they are upgraded.

The host can be accessed before upgraded to 6.7u2, but now it can't.

I don't know why for the network configuration is no problem I think. And the physical Switch that the host connected is no problem also.

I know this question is so basic, but I cannot figure it out......I need some help, thank you!

Can you post some screenshots with your esxi host network config?

Hello There,

First test the Network Settings from the Host console itself, if they are able to resolve Gateway/DNS etc or not. Also check hostd, vpxa, logs etc for the error/warning events.

Also from the console please check if you are able to see uplink adaptors/NICs, sometimes there are hardware driver compatibilities with newer version of esxi.

Can you confirm that you've used the Dell customized ESXi image (https://my.vmware.com/group/vmware/details?downloadGroup=OEM-ESXI67U2-DELLEMC&productId=742), which contains additional drivers for devices used in Dell servers?

well, really, I just download the image from vmware but not the Dell customized....I'll try this one! Thank you!

I think all these service are running, and the test from the console is failed. Maybe is because the iso image I download is not the Dell customized version. I think I should try this one first.

I have found a way to get this problem. First don't trunk the uplink when you just installed the esxi host, then I log in the vcenter, connected the host, add the host to my cluster, and configure the network. After add all adapters of the host to the uplinks, then turned these network interfaces to trunk in the switch. Everything is ok.
