Disable Network Rollback by Using the vCenter Server
Configuration File
Rollback is enabled by default in vSphere 5.1 and later. You can disable rollback by editing the vpxd.cfg
configuration file of vCenter Server directly.
Procedure
1 On the host machine of vCenter Server, navigate to the directory that contains the configuration file:
n
On a Windows Server operating system, the location of the directory is
C:\ProgramData\VMware\CIS\cfg\vmware-vpx.
n
On the vCenter Server Appliance, the location of the directory is /etc/vmware-vpx.
2 Open the vpxd.cfg file for editing.
3 In the <network> element, set the <rollback> element to false:
<config>
<vpxd>
<network>
<rollback>false</rollback>
</network>
</vpxd>
</config>
4 Save and close the file.
5 Restart the vCenter Server system.
Resolve Errors in the Management Network Configuration
on a vSphere Distributed Switch
In vSphere 5.1 and later, you can use the Direct Console User Interface (DCUI) to restore the connection
between vCenter Server and a host that accesses the management network through a distributed switch.
If networking rollback is disabled, misconfiguring the port group for the management network on the
distributed switch leads to loss of connection between vCenter Server and the hosts that are added to the
switch. You have to use the DCUI to connect each host individually.
