Most of the commands in this appendix are reserved for Technical Support use and are included for your
reference only. In a few cases, however, these commands provide the only means of performing a configuration
task for the host. Also, if you lose your connection to the host, executing certain of these commands through
the command-line interface may be your only recourse—for example, if networking becomes nonfunctional
and vSphere Client access is therefore unavailable.
NOTE : If you use the commands in this appendix, you must execute the service mgmt-vmware restart
command to restart the vmware-hostd process and alert the vSphere Client and other management tools that
the configuration has changed. In general, avoid executing the commands in this appendix if the host is
currently under the vSphere Client or vCenter Server management.
The vSphere Client graphical user interface provides the preferred means of performing the configuration
tasks described in this topic. You can use this topic to learn which vSphere Client commands to use in place
of these commands. This topic provides a summary of the actions you take in vSphere Client, but does not
give complete instructions. For details on using commands and performing configuration tasks through
vSphere Client, see the online help.
esxcfg-advcfg : Configures advanced options for ESXi. To configure advanced options in vSphere Client, click Advanced Settings. When the Advanced Settings dialog box opens, use the list on the left to select the device type or activity you want to work with and then enter the appropriate settings.
esxcfg-dumppart :Configures a diagnostic partition or searches for existing diagnostic partitions.
When you install ESXi, a diagnostic partition is created to store debugging information in the event of a system fault. You don’t need to create this partition manually unless you determine that there is no diagnostic partition for the host.You can perform the following management activities for diagnostic partitions in
vSphere Client:
n Determine whether there is a diagnostic partition —
Click Storage>AddStorage and check the first page of the Add Storage Wizard to see
whether it includes th. If Diagnostic is not one of the options,ESXi already has a diagne Diagnostic optionostic partition.n Configure a diagnostic partition — Click Storage>Add Storage>Diagnostic and
step through the wizard.
esxcfg-info Prints information about the state of the VMkernel and various subsystems in the
virtual network, and storage resource hardware.vSphere Client doesn’t provide a method for printing this information, but you can obtain much of it through different tabs and functions in the user interface. For
example, you can check the status of your virtual machines by reviewing the
information on the Virtual Machines tab.
esxcfg-init Performs internal initialization routines. This command is used for the bootstrap
process you should not use it under any circumstances. Using this command can cause problems for ESXi.
There is no vSphere Client equivalent for this command.
esxcfg-module Sets driver parameters and modifies which drivers are loaded during startup. This
command is used for the bootstrap process and is intended for VMware Technical Support use only. You should not issue this command unless instructed to do so by a VMware Technical Support representative.
There is no vSphere Client equivalent for this command.
esxcfg-mpath Configures multipath settings for your Fibre Channel or iSCSI disks.To configure multipath settings for your storage in vSphere Client, click Storage.Select a datastore or mapped LUN and click Properties. When the Properties dialogbox opens, select the desired extent if necessary. Then, click Extent Device>ManagePaths and use the Manage Path dialog box to configure the paths.
esxcfg-nas Manages NFS mounts. You use this command to create or unmount an NFS datastore.
To view NFS datastores in vSphere Client, click Storage > Datastores and scroll
through the datastores list. You can also perform the following activities from the
Storage > Datastores view:
n Display the attributes of an NFS datastore – Click the datastore and review the
information under Details.
n Create an NFS datastore – Click Add Storage.
n Unmount an NFS datastore – Click Remove, or right-click the datastore to
unmount and select Unmount.
esxcfg-nics Prints a list of physical network adapters along with information on the driver, PCI
device, and link state of each NIC. You can also use this command to control a physical
network adapter’s speed and duplexing.
To view information on the physical network adapters for the host in vSphere Client,
click Network Adapters.
To change the speed and duplexing for a physical network adapter in the vSphere
Client, click Networking>Properties for any of the virtual switches associated with
the physical network adapter. In the Properties dialog box, click Network
Adapters>Edit and select the speed and duplex combination.
esxcfg-resgrp Restores resource group settings and lets you perform basic resource group
management.
Select a resource pool from the inventory panel and click Edit Settings on the
Summary tab to change the resource group settings.
esxcfg-route Sets or retrieves the default VMkernel gateway route and adds, removes, or lists static
routes.
To view the default VMkernel gateway route in vSphere Client, click DNS and
Routing. To change the default routing, click Properties and update the information
in both tabs of the DNS and Routing Configuration dialog box.
esxcfg-swiscsi Configures your software iSCSI software adapter.
To configure your software iSCSI system in vSphere Client, click Storage Adapters,
select the iSCSI adapter you want to configure, and click Properties. Use the iSCSI
Initiator Properties dialog box to configure the adapter.
esxcfg-scsidevs Prints a map of VMkernel storage devices. There is no vSphere Client equivalent for
this command.

Command Command Purpose and vSphere Client Procedure
esxcfg-vmknic Creates and updates VMkernel TCP/IP settings for vMotion, NAS, and iSCSI.
To set up vMotion, NFS, or iSCSI network connections in vSphere Client, click
Networking > Add Networking. Select VMkernel and step through the Add
Network Wizard. Define the IP address subnet mask and VMkernel default gateway
in the Connection Settings step.
To review your settings, click the blue icon to the left of the vMotion, iSCSI, or NFS
port. To edit any of these settings, click Properties for the switch. Select the port from
the list on the switch Properties dialog box and click Edit to open the port
Properties dialog box and change the settings for the port.
esxcfg-vswitch Creates and updates virtual machine network settings.
To set up connections for a virtual machine in vSphere Client, click Networking >
Add Networking. Select Virtual Machine and step through the Add Network
Wizard.
To review your settings, click the speech bubble icon to the left of the virtual machine
port group. To edit any of these settings, click Properties for the switch. Select the
virtual machine port from the list on the switch Properties dialog box, then click
Edit to open the port Properties dialog box and change the settings for the port.
