You are the administrator of a vSphere environment in which some performance issues have recently been reported. You want to closely examine various settings related to storage. You want to do most of this work at the command line with the intent that you may be able to build scripts for future use. You want to examine information on a particular storage device (LUN), such as its assigned multipath plug-in and its available paths. You want to examine statistics on each path.
