To resolve the issue:
- On the vSphere Client console, select the target ESXi host.
- Navigate to Configuration tab > Hardware > Networking.
- Under the Standard Switches section, make sure that the following conditions are met:
- Standard Switch vmservice-vswitch must exist.
- VMKernel Port vmservice-vmknic-pg must have the same IP address value as the VMKernel vNIC IP in the DSM.
If either of the two conditions above is not met, the error will occur.
- Reinstall the vShield Endpoint driver of the affected ESXi host from the vShield Manager console.
Reinstalling the vShield Endpoint driver does not require setting the ESXi host in Maintenance Mode.
- Synchronize the DSM and check again the Details of the target ESXi host. It should now show that the vShield Endpoint is "Installed" and the DSVA status is "Unprepared" for deployment.
