A system hard hang leaves the system unresponsive to a system break sequence. You
will know that a system is in a hard hang state when you have attempted all the soft
hang remedies with no success.
See "How to Troubleshoot a System That Is Hanging" on page 160.
Responding to Fatal Reset Errors and RED State
Exceptions
Fatal Reset errors and RED State Exceptions are most often caused by hardware
problems. Hardware Fatal Reset errors are the result of an "illegal" hardware state
that is detected by the system. A hardware Fatal Reset error can either be a transient
error or a hard error. A transient error causes intermittent failures. A hard error causes
persistent failures that occur in the same way.

SC Alert: Host System has Reset
SC Alert: Host System has read and cleared bootmode.
A RED State Exception condition is most commonly a hardware fault that is detected
by the system. There is no recoverable information that you can use to troubleshoot
a RED State Exception. The Exception causes a loss of system integrity, which would
jeopardize the system if Solaris software continued to operate. Because of this,
Solaris software terminates ungracefully without logging any details of the RED
State Exception error in the /var/adm/messages file.
