7-52 Troubleshooting
COLLECTION OF THE MEMORY DUMP
If a failure occurs, the memory data should be dumped to acquire the required information. If you
stored the dump data in a DAT, label it so as to indicate the software (e.g. NTBackup) you used for
storing it. You may save the diagnosis data to a desired destination.
IMPORTANT:
Consult with your sales agent before dumping the memory. Executing memory dumping
while the server is in the normal operation may affect the system operation.
Restarting the system due to an error may display a message indicating insufficient virtual
memory. Ignore this message and proceed. Restarting the system again may result in
dumping improper data.
Preparing for Memory Dump
Memory dumping with the DUMP switch may disable the server to restart. In such a case, it is
required to force the server to shut down. This forced shutdown, however, is not available if
"Enabled" is selected for "Switch Inhibit" on the Security menu of the BIOS setup utility, SETUP,
because this setting disables POWER switch operation.
Follow the procedure below to change the setting to enable the forced shutdown and restart of the
server.
1.
Power on the server and start the BIOS setup utility, SETUP.
2.
Select "Disabled" for "Switch Inhibit" in the Security menu.
3.
Save the configuration data and exit the SETUP.
Saving Dump Files
Press the DUMP (NMI) switch to save the dump file
when an error occurs. Insert something
sharp-pointed like a pen into the switch hole to press
the DUMP switch.
Pressing the DUMP switch saves the dump file in
the specified directory. (Memory dumping may not
be available when the CPU stalls.)
IMPORTANT:
Do not use a toothpick or plastic
stick that is easy to break.
