Reset the System Configuration
If you are having trouble determining the source of a problem with your ESXi host, you can reset the
system configuration.
Changes in the system configuration can be related to various problems, including problems with
connectivity to the network and devices. Resetting the system configuration might solve such problems. If
resetting the system configuration does not solve the problem, it can still rule out configuration changes
made since the initial setup as the source of the problem.
When you reset the configuration, the software overrides all your configuration changes, deletes the
password for the administrator account (root), and reboots the host. Configuration changes made by your
hardware vendor, such as IP address settings and license configuration, might also be deleted.
Resetting the configuration does not remove virtual machines on the ESXi host. After you reset the
configuration defaults, the virtual machines are not visible, but you make them visible again by
reconfiguring storage and reregistering the virtual machines.
Caution When you reset the configuration defaults, users accessing the host lose connectivity.
Prerequisites
Before resetting the configuration, back up your ESXi configuration in case you want to restore your
configuration.
Procedure
1 Back up the configuration using the vSphere CLI vicfg-cfgbackup command.
2 From the direct console, select Reset System Configuration and press Enter.
3 Press F11 to confirm.
The system reboots after all settings are reset to the default values.
After You Install and Set Up ESXi
After ESXi is installed and set up, you can manage the host by using the vSphere Web Client and
vCenter Server, license the host, and back up your ESXi configuration.
You can also use the VMware Host Client to connect directly to the ESXi host and to manage it. For
information about installing and using the VMware Host Client, see vSphere Single Host Management.
Managing the ESXi Host
The VMware Host Client provides the simplest way to manage your ESXi host and operate its virtual
machines.
You can also use the vSphere Web Client to connect to and manage vCenter Server by using a Web
browser. The vSphere Web Client is installed together with vCenter Server and the
vCenter Server Appliance and you can use it to manage your ESXi hosts.
