Soft
Errors
Soft errors are
intermittent
failures
or
failures
that
occur while
the
operating
system is
running. Here are
the
basic steps in troubleshooting soft failures.
• Determine
the
environment.
• Check
the
error logs.
•
Run
diagnostics.
• Take
appropriate
action.
You
must
determine
the
environment. This means observing
the
front panel LEDs
and
any
console messages. You should also check all
error
logs in
the
system
and
peripheral devices,
if
appropriate.
If
needed, there are
both
offline
and
online diagnostics, as well as a system exerciser,
that
you
can use
to
troubleshoot
the
failure. Once you determine
the
cause
of
the
failure, you can act
accordingly.
Diagnostic
Tools
Online Diagnostics

online diagnostics require a user license

To access
the
diagnostics,
type
SYSDIAG
at
the
operating
system
prompt.
At
the

display a list of
the
online diagnostics supported.
If
you
type
list long
you will get a detailed listing
of
the
available diagnostics with information
about
the
specific
devices
tested
by
the
diagnostic. Help is available for each one.
You can find detailed information
about
the
online diagnostics
in
the
Diagnostic Manual Set.
System Log File Procedure
One of
the
online diagnostics available is

You can use logtool

the
system
logs.

with all
the
online diagnostics, only licensed users can use logtool.
Perform
the
following procedure
to
display
the
