SC Alert: Host System has Reset
SC Alert: Host System has read and cleared bootmode.
In some isolated cases, software can cause a Fatal Reset error or RED State
Exception. Typically, these are device driver problems that can be identified easily.
You can obtain this information via SunSolve Online (see "Web Sites" on page 106),
or by contacting Sun or the third-party driver vendor.
The most important pieces of information to gather when diagnosing a Fatal Reset
error or RED State Exception are:
System console output at the time of the error
Recent service history of systems that encounter Fatal Reset errors or RED State
Exceptions
Capturing system console indications and messages at the time of the error can help
you isolate the true cause of the error. In some cases, the true cause of the original
error might be masked by false error indications from another part of the system.
For example, POST results (shown by the output from the prtdiag command)
might indicate failed components, when, in fact, the "failed" components are not the
actual cause of the Fatal Reset error. In most cases, a good component will actually
report the Fatal Reset error.
By analyzing the system console output at the time of the error, you can avoid
replacing components based on these false error indications. In addition, knowing
the service history of a system experiencing transient errors can help you avoid
repeatedly replacing "failed" components that do not fix the problem.
