Uninstalling NSX-T from a Host Transport Node fails: Unable to clear DVS propertycom.vmware.nsx.vdl2.enabled: Status(bad0004)= Busy

Products

• VMware NSX

Issue/Introduction

• Removing NSX gracefully from the UI fails.
• Removing NSX from the ESXi host directly via the NSXCLI with the 'nsxcli -c del nsx' command fails.
• On the ESXi host the following vDS property is observed to be RUNTIME instead of expected CONFIG

#net-dvs | grep "com.vmware.common.opaqueDvs.status.component.vswitch"
          com.vmware.common.opaqueDvs.status.component.vswitch = up ,     propType = RUNTIME

• In the NSX-T Manager log '/var/log/syslog' we see the following entries during failed removal from the NSX-T UI:

Host configuration: host switch remove operation failed: [Failed to hot-swap cvds [\'50 ## a0 ## e3 ## 14 ##-c3 ## bc ## a5 ## 5d ##\']ApplyNsxDvsConfig on (50 ## a0 ## e3 ## 14 ##-c3 e2## a7 ## e0 ## 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\']}];  LogicalSwitch full-sync: LogicalSwitch full-sync realization query skipped.

• In the ESXi log /var/run/log/nsxcli.log after we run the 'del nsx' command we see the following entry:

% Exception when deleting nsx from host: ' error code: 4 stdout: delete_nsx_instance_from_host.sh: INFO: NSX reset script called with argument fabric_node on nsx-esx delete_nsx_instance_from_host.sh: INFO: Run transport_node reset on ESX node % Failed to remove all host switches or logical switches delete_nsx_instance_from_host.sh: ERROR: Failed to reset nsxa app of nsx-opsagent. Please check ospagent logs for more details. , stderr: Tue May 02 2023 UTC 15:00:54.002 ERROR: Failed to reset nsxa app of nsx-opsagent. Please check ospagent logs for more details.'

Environment

VMware NSX

Cause

This issue occurs due to a change in API behaviour when updating the status of vDS properties.

Resolution

This issue is resolved in NSX versions 3.2.4, 4.1.2 and newer releases

Workaround

 

• Execute the following commands from the ESXi shell:
• Check the vDS name:

    #net-dvs | grep "com.vmware.common.alias"

• Correct the problematic vDS property:

#net-dvs -s com.vmware.common.opaqueDvs.status.component.vswitch=up -p hostPropList <vDS Name>

use <vDS Name> from previous step

• Now continue with uninstall of the host with the 'nsxcli -c del nsx' command
