Collection Of The Memory Dump - NEC NovaScale R630 User Manual

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.
Press the DUMP switch on the primary CPU/IO module, whose POWER LED has been blinking, for four to
eight seconds. Use something sharp, such as curved clips to press the DUMP switch on CPU/IO module 1.
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.
Saving Dump Files
Press the DUMP (NMI) switch on the primary CPU/IO module
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.
