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.

Prerequisites

Before reverting changes, use the vCenter Server Management interface to perform a backup of the vCenter Server.

Procedure

  1. Connect to the vCenter Server where you want to revert changes 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-TlsReconfigurator/VcTlsReconfigurator
  4. Review the previous backup. 
    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
  5. Run the following command to perform a restore. 
    reconfigureVc restore -d Directory_path_from_previous_step
    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
  6. Repeat the procedure on any other vCenter Server instances.
