An ESXi host is in an orphaned state in the NSX-T manager.In an attempt to clean it up and rebuilt it, del nsx command was run in the nsxcli of the host and failed.On the ESXi logs /var/run/log/nsxaVim.log we see the following log entry: nsxaVim: [2102769]: ERROR ApplyNsxDvsConfig on (50 0d a0 72 e3 8d 15 44-c3 e2 bd a7 a5 e0 5d 98) failed: {'fault': 'PlatformConfigFault', 'msg': 'An error occurred during host configuration.', 'faultMessage': ['Operation failed, diagnostics report: Unable to clear DVS propertycom.vmware.nsx.vdl2.enabled: Status(bad0004)= Busy']}^@nsxaVim: [2102769]: ERROR Failed to hot-swap cvds ['50 0d a0 72 e3 8d 15 44-c3 e2 bd a7 a5 e0 5d 98']^@nsxaVim: [2102769]: INFO HotSwapCvds result: Failed to hot-swap cvds ['50 0d a0 72 e3 8d 15 44-c3 e2 bd a7 a5 e0 5d 98']ApplyNsxDvsConfig on (50 0d a0 72 e3 8d 15 44-c3 e2 bd a7 a5 e0 5d 98) failed: {'fault': 'PlatformConfigFault', 'msg': 'An error occurred during host configuration.', 'faultMessage': ['Operation failed, diagnostics report: Unable to clear DVS propertycom.vmware.nsx.vdl2.enabled: Status(bad0004)= Busy']}^@ ...nsxaVim: [2102769]: INFO Invoking ApplyDvsList: dvsParams: ;reset=True;management;deleteTn=True | preDvsList: ['']nsxaVim: [2102769]: INFO dvs to reset [[]]
This issue occurs when the list of DVS's to be cleared are empty, as seen in the log entry above (INFO dvs to reset [[]]) and del nsx is unable to remove NSX-T from the host.
This is a known issue impacting VMware NSX.
First, manually remove the VTEP vmkernel interfaces on the ESXi host: esxcli network ip interface remove --interface-name=vmk10 - repeat for all VTEP vmkernel interfaces. Then, manually remove the VTEP, vdrPort and spfPort ports from the DVS: net-dvs [ -A | -D ] -p port switch_name - add/delete a port from a dvswitch Sample command: net-dvs -D -p xxxxxxxx-9801-4fed-xxxxxxxxxxxx dvs-name To find the port used for the VTEP/vdrPort/spfPort , run the command: net-dvs -l -> then search the results for VTEP and the port should be listed just above the word VTEP, i.e. if you have 2 VTEP's, you should see the entry twice and need to run the command twice to remove both VTEP ports from the DVS. Run del nsx again on the ESXi host.If this still fails, you can run the following command, to force the hot swap of the CVDS to DVS: ./usr/lib64/vmware/nsx-opsagent/bin/nsxcfg-vswitch -s Then rerun del nsx again to complete the removal of NSX-T from the ESXi host.
