The CLI command line tool esxcfg-advcfg can be used to query and modify advanced options for a wide variety of different aspects of the ESX 3/4 VMkernel, such as resources, networking, storage and global settings. Note that this page is written for ESX 4 and not all commands may work with ESX 3.

Options

Option	Alternative Option	Description
-g	--get	Get the value of a specified configuration item
-s	--set	Set the value of a specific configuration item. This may fail silently, if the value given is constrained by other options or VMkernel settings.
-d	--default	Set the value of a specified configuration item to the default value defined by the VMkernel.
-q	--quiet	Perform any of the other options but don’t print the output to stdout
-k	--set-kernel	Set a VMkernel boot parameter
-j	--get-kernel	Get the value of a VMkernel boot parameter
-h	--help	Print a command usage message
-r	--restore	Read the contents of the configuration file, and perform a set for each of the advanced options in the file
-c	--get-config	Get the value of a specific line in esx.conf
-m	--set-message	Set DCUI welcome message
-u	--uuid	Ensure the VMkernel system UUID is set and print it
-U	--user-var	The name of the user variable to use for: --get-user-var, --set-user-var, and --del-user-var
-G	--get-user-var	Get the value of a user specified generic value. Requires the --user-var option
-S	--set-user-var	Set the value of a user specified generic value. Requires the --user-var option
-D	--del-user-var	Delete the value of a user specified generic value. Requires the --user-var option
-A	--add-option <name>	This adds and advanced variable to /UserVars tree of the Advanced Options. This is different to the --user-var options, which do not show in the VCUI and only contain simple user vars for use at boot time. An advanced option requires the --add-type, --add-desc, --add-default, --add-name and --add-min, --add-max if type in int.
-T	--add-type	The type of user advanced option to add, must be either string or int
-E	--add-desc	The description of the user advanced option to add
-F	--add-default	The default value of the user advanced option to add
-N	--add-min	The min value of the user advanced option to add (int only)
-M	--add-max	The max value of the user advanced option to add (int only)
-H	--add-hidden <value>	The hidden value of the user advanced option to add. Must be either true or false. Default = false
-L	--del-option <name>	Delete a UserVars advanced option added with the -A command
-V	--has-option <name>	Return 0 from the command if the option exists return 1 otherwise
