Dump And Go; Online Diagnostic Codes - NEC Express5800/320Ma Administrator's Manual

Dump files beyond this number overwrite the existing saved dump files. For
instance, if the value is 3, then the fourth saved dump file overwrites the first,
existing dump file.
If, at the time of a system crash, the DumpQuickEnabled property of the Board
Instance Driver node is True and the CPU element is duplex, the system creates a
memory dump and stores the dump in the memory of one CPU element. The system
restarts with the remaining CPU element. After the system restarts, the dump is
automatically copied to a disk file.
After a system reboot where a dump has been generated, do not attempt to read or
copy the Memory.dmp file created. After the system has completed writing the
Memory.dmp file, it renames the file Memoryn.dmp, where n is a numeral. You can
read or copy the Memoryn.dmp file. It may take up to five minutes after the reboot to
complete writing the Memory.dmp file before it is renamed and can be read.
!
The normal Windows dump mechanism is used if the DumpQuickEnabled parameter
is False (disabled) or if the CPU element is in simplex mode.

Dump and Go

The Dump and Go command captures a snapshot dump of a running system or a
particular component without significantly interfering with the system's or component's
operation. The system must be running duplex in order to use this method. To capture
a snapshot dump, right-click the CPU Enclosure node of interest in the ftSMC console
tree and select Dump and Go from the Action menu. The system:
•
Takes the selected CPU element offline with its memory intact
•
Dumps a snapshot of the memory to C:\sradumps\Memoryn.dmp
•
Displays the status of the operation
•
Returns the CPU element back to online status
A Dump and Go command on a BMC controller dumps a snapshot of the BMC
firmware's memory, and then restores the BMC to service.

If you attempt to read or copy the Memory.dmp file while
the system is writing it, you may corrupt the file.
