Distributed Switch name reverting back to old name after ESXi host reboot

Products

• VMware vCenter Server
• VMware NSX

Issue/Introduction

After creating a Distributed switch, adding a host and configuring the Transport Node, if the name of the distributed switch is changed to a new name, it will revert back to the original name on the host once the host is rebooted.

while vCenter, SDDC manager or NSX manager show the new name, on the host the name is changed back to the original name after reboot.

All commands on the host such as net-dvs show the old name of the distributed switch after reboot.

There is no impact or network issue on the production.

Environment

NSX version 4.2.1

NSX version 9.0

Cause

This is due to the NSX agent changing the name back to the old name after the host is rebooted.

 

Resolution

This is a known issue and Engineering is working on a permanent fix

Workaround : 

Change the distributed switch name in vCenter to the old name, then change it back to the new name for the host to be updated.

This is only temporary until the host next reboot.
