If there is a catastrophic failure, the
DCUI.Access advanced option allows you to exit lockdown mode 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 Client.
- Browse to the host in the vSphere Client inventory.
- Click Configure.
- Under System, click Advanced System Settings, and click Edit.
- Filter for DCUI.
- In the DCUI.Access text box, enter the local ESXi user names, separated by commas.
By default, the root user is included. Consider removing the root user from the DCUI.Access list, and specifying a named account for better auditability.
- Click OK.
