7-32 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

"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.
