Collecting Memory Dump

If an error occurs, the dump file should be saved to acquire necessary information. You can specify any
location for saving the diagnostic information. For details, see Chapter 1 (6.1 Specifying Memory Dump
Settings (Debug Information)) in "Installation Guide (Windows)".
Consult with your sales representative before dumping the memory. Dumping the memory while the server is in
operating normally may affect the system operation.
Press DUMP Switch to save the dump file if an error occurs. Insert a metal pin (a straightened large paper clip
will make a substitute) into the switch hole to press DUMP Switch.
Pressing DUMP Switch saves the dump file in the specified directory. (Memory dumping may not be available
when the CPU stalls.)
Important
•
A message indicating insufficient virtual memory may appear when
restarting the system due to an error. Ignore this message and proceed.
Restarting the system may result in an inability to properly dump the
data.
•
In disk array configuration, dump data may not be acquired if the array is
not ready to boot.
