Collection of the Memory Dump
If a failure occurs, the memory data should be dumped to acquire the required information.
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
"Masked" is selected for "Power Switch Mask" 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 "Unmasked" for "Power Switch Mask" in the Security menu.
3. Save the configuration data and exit the SETUP.
Saving Dump Files
Press the DUMP switch to save the dump file
when an error occurs. Insert a metal pin (a
straightened large paper clip will make a
substitute) 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.)
Dump switches
IMPORTANT: Do not use a toothpick or
plastic stick that is easy to break.
When the DUMP switch is pressed, the system restarts and collects the memory dump.
