Testing the System

The Sun Fire E25K/E20K systems use setkeyswitch to diagnose system problems
by running hpost(1M) when posting a domain. The hpost(1M) diagnostic probes,
configure and test the domain hardware, preparing the system to run OpenBoot™
PROM and subsequently the Solaris OS.
The Sun VTS™ diagnostics suite can be used as a verification of a dynamic system
domain or an SC. To use the sunvts(1M) command, you must be logged into the
host as superuser. Information about sunvts(1M) is located in
/opt/share/man/man1m.
Verify the SMS is up and running by typing:
