Adding New host to Nexus 1000v fails

[gstoek]

Hi Community,

We try to add New hosts to an existing N1kv.

vem Module is installed successfully, but when we try to add the host in vcenter, we get the following error Message:

vDS operation failed on host xxxxxxx, An error occurred during host configuration. got (vim.fault.PlatformConfigFault) exception

Currently, Nx-os Version 4.2 (1) SV2 (1.1a) is installed, vem Version is also correct:

~ # vem status -v

Package vssnet-esxmn-next-release

Version 4.2.1.2.1.1a.0-3.1.1

Hello,

The error on the vCenter GUI is a generic one. You could look at the vpxa logs of the ESX host to see a better description of the error (hopefully). A blind step that works in a majority of these cases is a host reboot. It's not a N1k error - more on the VMware side.

Thanks,

Hey guys,

I faced the same problem some time ago.

What I did and worked after a long troubleshooting process, was update the Vcenter and ESXi to the same version and install the Update Manager.

After all this, it finally worked for me.

HI Spankar,

a reboot did not help. The new host has the same ESXi version as the other 16 Hosts, which are already running with N1kv.

We have opeend a Case at VMware....

Sure, please update the thread with the answer once you've found it. And if possible, attach a 'vm-support' to this thread.

Thanks,
