How do perform a quick network health check using Application Runtime Expert

There are various ways you can do this, but perhaps the simplest is to simply start the QShell environment with STRQSH and work from there.
To run the network health checker, you use the following incantation:

HMCScanner - a useful tool to complement the System Planning Tool

Documenting a virtual server environment is an absolute necessity these days. The relationships between physical and virtual resources can be very easily confused.
The Hardware Management Console (HMC) has a built in feature to create a System Plan. This tool creates an exportable set of tables that document much of a Power Systems server environment.

Another tool exists on IBM developWorks that does even more. The HMC Scanner is a Java based program that uses secure shell (SSH) to connect to your HMC, scan the server environment, and produce a finished spreadsheet.
The nice thing about this approach is that you can view, modify, and store this data on any device that can read a spreadsheet.
