You can use the TLS Configuration utility to revert configuration changes. When you revert the changes, the system enables protocols that you disabled using TLS Configurator utility.

You can only perform a recovery if you previously backed up the configuration.

Perform recovery in this order.
  1. vSphere Update Manager.

    If your environment runs a separate vSphere Update Manager instance on a Windows system, you have to update vSphere Update Manager first.

  2. vCenter Server
  3. Platform Services Controller

Procedure

  1. Connect to the Windows machine or the appliance.
  2. Log in to the system where you want to revert changes.
    OS Procedure
    Windows
    1. Log in as a user with Administrator privileges.
    2. Go to the VcTlsReconfigurator directory. 
      cd C:\Program Files\VMware\CIS\vSphereTlsReconfigurator\VcTlsReconfigurator
    Linux
    1. Connect to the appliance using SSH and log in as a user who has privileges to run scripts.
    2. If the Bash shell is not currently enabled, run the following commands. 
      shell.set --enabled true
shell
    3. Go to the VcTlsReconfigurator directory. 
      cd /usr/lib/vmware-vSphereTlsReconfigurator/VcTlsReconfigurator
  3. Review the previous backup.
    OS Procedure
    Windows 
    C:\ProgramData\VMware\vCenterServer\logs\vSphere-TlsReconfigurator\VcTlsReconfigurator.log

    The output looks like the following example. 

    c:\users\username\appdata\local\temp\20161108T161539
c:\users\username\appdata\local\temp\20161108T171539
    Linux 
    grep "backup directory" /var/log/vmware/vSphere-TlsReconfigurator/VcTlsReconfigurator.log

    The output looks like the following example. 

    2016-11-17T17:29:20.950Z INFO Using backup directory: /tmp/20161117T172920
2016-11-17T17:32:59.019Z INFO Using backup directory: /tmp/20161117T173259
  4. Run one of the following commands to perform a restore.
    OS Procedure
    Windows 
    reconfigureVc restore -d Directory_path_from_previous_step

    For example 

    reconfigureVc restore -d c:\users\username\appdata\local\temp\20161108T171539
    Linux 
    reconfigureVc restore -d Directory_path_from_previous_step

    For example 

    reconfigureVc restore -d /tmp/20161117T172920
  5. Repeat the procedure on any other vCenter Server instances.
  6. Repeat the procedure on any other Platform Services Controller instances.
