Like the last several posts, this one hails from the storage section of the Enterprise Admin Blueprint. The Enterprise Admin exam is one of the several requirements to becoming a VCDX. As I go down this path, I hope to share with you some of my exam prep in the hope that it will help you as well.
Seems this is becoming part of a series. Like the last few posts, this one was also produced from objective 1.1 of the VCDX Blueprint, and is part of my exam prep.
Task:
esxcfg-module – Unload/Load modules & check module status.
The Command:
[root@ProfessionalVMware root]# esxcfg-module
Usage: esxcfg-module <options> <module>
-g|–get-options Get the options for a given module and whether it is loaded on boot.
-s|–set-options Set the options for a given module.
WARNING this may be overwritten by per device options.
-e|–enable Enable a given module, indicating it should be loaded on boot.
-d|–disable Disable a given module, indicating it should not be loaded on boot.
-q|–query Query enabled modules options.
-l|–list List all modules and whether they are enabled.
-h|–help Show this message.
In this case I’ve only included the relevant output.
