VM Cannot Be Created During Move/Failover due to Computer Name Character Limitation

KB Number:

Solution:

Purpose


When specifying the Computer Name on a Windows machine to be longer than 15 characters, an error message is displayed. Despite the error, the change is still performed.  Although Windows will allow names greater than 15 to be specified, this causes problems in vCD.  When a vCD VM is marked as being re-IP'd in Zerto, the computer name must be
provided in order to deliver the re-IP customization package through vCenter
and VMware Tools.  

 

Zerto Virtual Replication receives this information from the VM itself via VMware Tools. The
retrieved computer name is then specified as the NETBIOS name in the
customization package, which has a character limit of 15 for use within vCD.  
This limitation is documented in the VMware Documentation on Editing Virtual Machine Properties in vCloud Director.

If the Computer Name retrieved is greater than 15 characters, the Zerto Re-IP operation will fail with the following error:
