Host encryption mode is enabled automatically when you perform an encryption task. After host encryption mode is enabled, all core dumps are encrypted to avoid the release of sensitive information to support personnel. If you no longer use virtual machine encryption with an ESXi host, you can disable encryption mode.

Procedure

  1. Unregister all encrypted virtual machines from the host.
  2. Unregister the host from vCenter Server.
  3. Reboot the host.
  4. Register the host with vCenter Server again.

Results

If you do not add encrypted virtual machines to the host, host encryption mode is disabled.
