Environment

VMware vCenter Server 6.5.x

Cause

This issue occurs due to an IP conflict.

Resolution

To resolve this issue:

1. Log in to the VCSA ( failed installation ) through the console.
2. Log in to shell on the console.
3. To get MAC address for the device that is retaining/using the IP address, run this command:
   
   arping -D <IP address>
    
4. Ensure that there is no IP conflict or use a different IP Address to prevent this error.
5. Remove the Appliance that was created during the failed deployment or migration.
6. Repeat the deployment of the vCenter Server Appliance or the Migration of the Windows based vCenter Server to an Appliance.
