These topics provide information about using the direct console user interface and configuring defaults for ESXi. ESXi AutoconfigurationWhen you turn on the ESXi host for the first time or after resetting the configuration defaults, the host enters an autoconfiguration phase. This phase configures system network and storage devices with default settings. About the Direct Console ESXi InterfaceUse the direct console interface for initial ESXi configuration and troubleshooting. Set the Password for the Administrator AccountYou can use the direct console to set the password for the administrator account (root). Configuring the BIOS Boot SettingsIf your server has multiple drives, you might need to configure the BIOS settings. Host Fails to Boot After You Install ESXi in UEFI ModeWhen you install ESXi on a host machine in UEFI mode, the machine might fail to boot. Network Access to Your ESXi HostThe default behavior is to configure the ESXi management network using DHCP. You can override the default behavior and use static IP settings for the management network after the installation is completed. Configure the Network Settings on a Host That Is Not Attached to the NetworkSome highly secure environments do not permit unconfigured hosts on the network to be powered on. You can configure the host before you attach the host to the network. Managing ESXi RemotelyYou can use the vSphere Web Client and vCenter Server to manage the host. Configuring Network SettingsESXi requires one IP address for the management network. To configure basic network settings, use the vSphere Web Client or the direct console. Storage BehaviorWhen you start ESXi, the host enters an autoconfiguration phase during which system storage devices are configured with defaults. View System LogsSystem logs provide detailed information about system operational events. Configure Syslog on ESXi HostsAll ESXi hosts run a syslog service (vmsyslogd), which logs messages from the VMkernel and other system components to log files. Enable Lockdown Mode Using the Direct ConsoleTo increase the security of your ESXi hosts, you can put them in lockdown mode. Enable Lockdown Mode Using the vSphere Web ClientEnable lockdown mode to require that all configuration changes go through vCenter Server. You can also enable or disable lockdown mode through the Direct Console User Interface (DCUI). Enable ESXi Shell and SSH Access with the Direct Console User InterfaceUse the direct console user interface to enable the ESXi Shell. Set the Host Image Profile Acceptance LevelThe Host Image Profile acceptance level determines which vSphere installation bundles (VIBs) are accepted for installation. Reset the System ConfigurationIf you are having trouble determining the source of a problem with your ESXi host, you can reset the system configuration. Remove All Custom Packages on ESXiAfter adding custom packages, you might decide to remove them. Disable Support for Non-ASCII Characters in Virtual Machine File and Directory NamesBy default, ESXi supports the use of non-ASCII characters for virtual machine file and directory names. You can disable this support by modifying the /etc/vmware/hostd/config.xml file. Disable ESXiIf you do not want your server to be an ESXi host, you can deactivate the ESXi setup.
