Leider gibt es aber keine einzige Funktion, die genauso funktioniert wie cediag -L, mit der man fehlerhafte Memories auslesen kann.

DESCRIPTION
cediag(1M) is a tool which analyzes memory error events and
makes DIMM replacement recommendations based upon the DIMM
Replacement Policy rules.

cediag is a perl script and, as such, requires that perl be
installed. Sun provides perl in the SUNWpl5u and SUNWpl5v
packages in Solaris 8 and later. For Solaris versions 7 and
earlier, perl version 5 or later must be obtained from a 3rd
party source. The cediag installation includes the symbolic
link /opt/SUNWcest/bin/perl which points to /usr/bin/perl.
If you cannot install the correct version of perl as
/usr/bin/perl, you can replace this link with a link to the
location of your perl installation.

When cediag is run with the first or second usage, it
analyzes information from the system on which it is running
to determine whether any DIMMs should be considered for
replacement. These usages are considered "live" mode. When
the -L option is specified in "live" mode, cediag appends
its analysis summary and recommended actions, including a
suggested timeframe for replacement if appropriate, to the
/var/adm/messages file. The output placed in /var/adm/messages is formatted to allow parsing by automated
monitoring tools. When run with the second usage, cediag
performs a full historical analysis on the system while the
first usage analyzes the currently running instance of
Solaris.

In the third and fourth usage formats, cediag runs in "stan-
dalone" mode. In this mode cediag analyzes log and messages
files collected from a remote system. In the second usage,
an uncompressed, extracted explorer output is provided for
analysis. cediag ascertains the configuration of the remote
system from various files in the explorer output and then
analyzes the memory errors from the /var/adm/messages files
in the explorer output. In the third usage, the user must
specify, via command line arguments, the configuration of
the system to be analyzed so that cediag can apply the
appropriate rules to the messages file(s), which is(are)
also supplied on the command line.

It is important to note that cediag is dependent on the CE
messages from Solaris to function properly. If CE messages
are disabled in your /etc/system file by setting the vari-
able ce_verbose_memory (or ce_verbose in older versions of
Solaris) to 0, then cediag will not provide accurate results
in "standalone" mode or in "live" mode for some versions of
Solaris. In those situation where cediag actually finds
ce_verbose_memory has been set to 0 in /etc/system, it will
give a warning message indicating some rule analysis results
may not be accurate.

The fifth usage of cediag displays whether the user has pre-
viously run the tool and correctly accepted the license. In
this usage, cediag exits with zero (0) if the license has
been accepted and with one (1) otherwise.

The sixth usage of cediag displays the version of the tool
and exits.

The last usage of cediag displays the help and usage message
for the tool and exits.

cediag supports Solaris 2.6 and later on UltraSPARC II,
UltraSPARC III, and UltraSPARC IV architecture systems. On
Solaris 10, except on UltraSPARC II-based systems, cediag
instructs the user to utilize the Predictive Self-Healing
features of the Operating System, such as fmadm(1M), for
memory system diagnosis.

For best results, cediag should be run on a daily basis to
analyze any system memory errors. cron(1M) can be used for
this purpose.

OPTIONS
The following options are supported.

-c SunOS,hostnameoversionDarchibe the hardware and software
configuration of the system which generated
the messages_file file(s). SunOS is a

literal string. Only messages produced by
the host named (case sensitive) hostname
will be analyzed by cediag. version is the
output of 'uname -r'. arch is the output of
'uname -p'.

-e explorer_directoryrer. Specifies the location of an
uncompressed, extracted explorer against
which cediag is to apply the DIMM Policy
rules. cediag uses the system configuration
information and /var/adm/messages file(s)
from the explorer to analyze the CEs exhi-
bited by the system.

-F Full History. When this option is speci-
fied, cediag analyzes all available messages
files on the current system and provides a
summary for every reboot of Solaris found.

-h Display tool help and usage and exit.

-I events Ignore events. At this time, events is lim-
ited to the letter 'r'. This prevents
cediag from resetting its accumulated CE
counts when it encounters a reboot in its
parsing.

-k KUP-rev Kernel Update Revision. This option speci-
fies which kernel update patch was installed
and running on the system which generated
the messages_file file(s). KUP is the
number of the Kernel Update Patch. rev is
the revision number of that Kernel Update
Patch.

-L Logging. Direct cediag to log its findings
and advice to the /var/adm/messages via
logger(1). Logging is off by default.

System Administration cediag(1M)

-l debug_file Logfile. Specify the file debug_file to
contain any text debugging information writ-
ten by cediag.

-M {d|e} Memory Page Retire (MPR) override. This
option applies to both "live" and "stan-
dalone" modes. When analyzing a system,
cediag must determine whether MPR is in use
on that system before it can apply the
appropriate policy rules. Though cediag
normally makes this determination automati-
cally, the -M option is provided to force
cediag to treat the system as if MPR were
enabled (with the e argument) or disabled
(with the d argument). Note the -M option
has no effect if cestat(1M) output is valid
or if cediag is analyzing messages from or a
system running Solaris 7 or earlier, Solaris
8 with patch 108528-23 or earlier, or
Solaris 9 with patch 112233-10 or earlier.

-s C:H Adjust Rule#6 to C CEs in H Hours.

-u US-version UltraSPARC chip version. Where US-version is
'1' for UltraSPARC I, '2' for UltraSPARC II,
'2e' for UltraSPARC IIe, '2i' for UltraSPARC
IIi, '3' for UltraSPARC III, '3i' for
UltraSPARC IIIi, '3+' for UltraSPARC III+
and '4' for UltraSPARC IV. Some Solaris
messages differ from one chip version to the
next. This option informs cediag what type
of chip generated the messages being
analyzed.

-V Version. Print the version of cediag and
exit.
-v Verbose. Print all CE statistics details.
Verbose is off by default.

OPERANDS
The following operands are supported:

messages_file Pathname to a /var/adm/messages file. Be
sure to specify files in ascending date
order.

EXTENDED DESCRIPTION
User Privileges Required
cediag can be run without superuser privileges. However, in
"live" mode cediag should be run with superuser privileges
for better performance on MPR systems.
