You can encounter errors when migrating VMkernel interfaces and physical NICs from a VSS or DVS switch to an N-VDS switch or revert migrating interfaces to a VSS or DVS host switch.

Table 1. VMkernel Migration Errors
Error Code Problem Cause Resolution
8224

Unable to find the host switch specified by the transport node configuration.

The host switch ID cannot be found.
  • Ensure that the transport zone is created with the host switch name and then create the transport node.
  • Ensure that a valid host switch is used in the transport node configuration.
8225

VMkernel migration is in progress.

Migration is in progress.

Wait for the migration to complete before performing another action.

8226

VMkernel migration is only supported on a ESXi host.

Migration is only valid for ESXi hosts.

Ensure that the host is a ESXi host before you initiate migration.

8227

VMkernel interface is not appended with the host switch name.

On a host with multiple host switches, NSX-T Data Center cannot identify association of each VMkernel interface with its host switch.

If the host has multiple N-VDS host switches, ensure the VMkernel interface is appended with the host switch name of the N-VDS the host is connected to.

For example, the network mapping for uninstallation of a host with N-VDS host switch name nsxvswitch1 and VMkernel1 and another N-VDS host switch name nsxvswitch2 and VMkernel2 must be defined as follows: device_name: VMkernel1@nsxvswitch1, destination_network: DPortGroup.

8228

Host switch used in the device_name field not found on the host.

Incorrect host switch name.

Enter the correct host switch name.

8229

Transport node did not specify the transport zone of the logical switch.

Transport zone not added.

Add the transport zone to the transport node configuration.

8230

No physical NIC on the host switch.

There must be at least one physical NIC on the host switch.

Specify at least one physical NIC to an uplink profile and the VMkernel network mapping configuration to a logical switch.

8231

Host switch name does not match.

If the host switch name used in vmk1@host_switch does not match the host switch name used by the destination logical switch of the interface.

Ensure that the host switch name specified in the network mapping configuration matches the name used by the logical switch of the interface.

8232

Logical switch not realized on the host.

Realization of logical switch on the host was unsuccessful.

Synchronize the host with the NSX Manager.

8233

Unexpected logical switch in the network interface mapping.

The network interface mapping for installation and uninstallation lists both logical switches and port groups.

Network mapping for installation must only contain logical switches as destination targets. Similarly, network mapping for uninstallation must only contain port groups as destination targets.

8294

Logical switch does not exist in the network interface mapping.

Logical switches not specified.

Ensure that logical switches are specified in the network interface mapping configuration.

8296

Host switch mismatch.

The network interface mapping for uninstallation is configured with the incorrect host switch name.

Ensure that the host switch name used in the mapping configuration matches the name entered on the host switch where the VMkernel interfaces reside on.

8297

Duplicate VMkernel.

Duplicate VMkernels are specified for migration.

Ensure that no duplicate VMkernel interfaces are specified in the installation or uninstallation mapping configuration.

8298

Mismatch of number of VMkernel interfaces and destinations.

Incorrect configuration.

Ensure that each VMkernel interface has a corresponding destination specified in the configuration.

8299

Cannot delete transport node as the VMkernel interface is using ports on N-VDS.

VMkernel interfaces are using ports from the N-VDS switch.

Revert the migration of all VMkernel interfaces from the N-VDS switch to a VSS/DVS switch. Then attempt to delete the transport node.

9412

VMkernel cannot be migrated from one N-VDS to another N-VDS.

Unsupported action.

Revert the migration of the VMkernel interface to a VSS or DVS switch. Then, you can migrate the VMkernel interface to another N-VDS switch.

9413

VMkernel interfaces cannot be migrated to a different logical switch.

On stateful hosts, a VMkernel connected to a logical switch cannot be migrated to another logical switch.

Revert the migration of the VMkernel from the logical switch to a VSS/DVS switch. Then, migrate the VMkernel to another logical switch on the N-VDS.

9414

Duplicate VMkernel interfaces.

Duplicate VMkernel interfaces mapped in the installation and uninstallation mapping configuration.

Ensure that each VMkernel interface is unique in the installation and uninstallation mappings.

9415

Powered on VMs on the host.

With powered on VMs, migration does not proceed.

Power off the VMs on the host before you initiate migration of VMkernel interfaces.

9416

VMkernel cannot be found on the host.

Did not specify a VMkernel that exists on the host in the network mapping configuration.

Specify a VMkernel that exists in the network mapping configuration.

9417

Port group not found.

Did not specify a port group that exists on the host in the network mapping configuration.

Specify a port group that exists in the network mapping configuration.

9419

Logical switch not found during migration.

Did not find the logical switch defined in the network interface mapping configuration.

Specify a logical switch that exists in the network interface mapping configuration.

9420

Logical port not found during migration.

During migration, NSX-T Data Center does not find the ports created on the logical switch.

Ensure that no logical ports are deleted from the logical switch for migration to be successful.

9421

Host information missing to validate the migration process.

Unable to retrieve host information from inventory.

Retry the migration process.

9423

Pinned physical NICs to a VMkernel interface are not migrated to the correct host switch.

A pinned physical NIC was found in the environment but the VMkernel and physical NIC are not being migrated to the same host switch.

A physical NIC pinned with VMkernel interface must have a transport node configuration that maps the physical NIC with the VMkernel on the same host switch.

600

Object not found.

The specified transport zone used by the logical switch does not exist.

The logical switch found in the VMK mapping destination cannot be found.

  • Specify a transport zone which exists in the environment.
  • Create the desired logical switch or use an existing VLAN logical switch.
8310

The logical switch type is incorrect.

The logical switch type is Overlay.

Create a VLAN logical switch.

9424

Cannot migrate if both PNIC only Migration and Network Mapping for install or uninstall settings are configured at the same time.

Migration progresses only when one of these settings is configured.

Ensure that either the PNIC only Migration or Network Mapping for install or uninstall setting is configured.
