show
This command shows a general summary of all detected controllers and
enclosures.
The output of this command will vary, depending upon your controller model
and whether there is an enclosure with an expander attached.
Note that the device drivers for the appropriate operating system should be
loaded for the list to show all controllers. The intention is to provide a global
view of the environment.
Example for controller without an enclosure and expander:
Typical output of the Show command for a controller looks like the following:
//localhost> show
