The main purpose of the DCUI.Access advanced option is to allow you to exit lockdown mode in case of catastrophic failure, when you cannot access the host from vCenter Server. You add users to the list by editing the Advanced Settings for the host from the vSphere Web Client.
About this task
Users in the DCUI.Access list can change lockdown mode settings regardless of their privileges. This can impact the security of your host. For service accounts that need direct access to the host, consider adding users to the Exception Users list instead. Exception user can only perform tasks for which they have privileges. See Specify Lockdown Mode Exception Users.
- Browse to the host in the vSphere Web Client object navigator.
- Click the Manage tab and select Settings.
- Click Advanced System Settings and select DCUI.Access.
- Click Edit and enter the user names, separated by commas.
By default, the root user is included. Consider removing root from the DCUI.Access, list and specifying a named account for better auditability.
- Click OK.
