Managing VMkernel Modules

The esxcli system module and vicfg-module commands support setting and retrieving VMkernel module options.

vicfg-module and esxcli system module commands are implementations of the deprecated esxcfg-module service console command. The two commands support most of the options esxcfg-module supports. vicfg-module and esxcli system module are commonly used when VMware Technical Support, a Knowledge Base article, or VMware documentation instruct you to do so.

Managing Modules with esxcli system module

Not all VMkernel modules have settable module options. The following example illustrates how to examine and enable a VMkernel. Specify one of the connection options listed in Connection Options in place of <conn_options>.

To examine, enable, and set a VMkernel modules

1	List information about the module.

esxcli <conn_options> system module list -module=module_name

The system returns the name, type, value, and description of the module.

2	(Optional) List all enabled or loaded modules.

esxcli <conn_options> system module list --enabled=true

esxcli <conn_options> system module list --loaded=true

3	Enable the model.

esxcli <conn_options> system module set --module=module_name --enabled=true

4	Set the parameter.

esxcli system module parameters set --module module_name --parameter-string="parameter_string"

5	Verify that the module is configured.

esxcli <conn_options> system module parameters list --module=module_name

Managing Modules with vicfg-module

Not all VMkernel modules have settable module options. The following example illustrates how the examine and enable a VMkernel modules. Specify one of the connection options listed in Connection Options in place of <conn_options>.

To examine and set a VMkernel modules

1	Run vicfg-module --list to list the modules on the host.

vicfg-module <conn_options> --list

2	Run vicfg-module --set-options with connection options, the option string to be passed to a module, and the module name. For example:

vicfg-module <conn_options> --set-options 'parameter_name=value' module_name

To retrieve the option string that is configured to be passed to a module when the module is loaded, run vicfg-module --get-options. This string is not necessarily the option string currently in use by the module.

vicfg-module <conn_options> --get-options module_name

Verifies that a module is configured.
