Online dump feature
If a failure or malfunction occurs on the ft server, you can collect memory dump by Online dump feature for
investigating the failure.
Important Collect dump upon request from maintenance personnel.
The dump file is collected with the same path and file name "
%SystemDrive%\NECDump\MEMORY.DMP
" as the
dump file of the OS standard.
Note

Dump collection can be performed only in the duplex system.

When memory dump is collected by Online dump feature, the CPU module becomes
the simplex state and memory dump is collected by one side of the CPU module
while the system is running. Therefore, if the system failure occurs while collecting
memory dump, there is a possibility that collecting memory dump is failed or the
system stops.

The duplicate of the CPU module after collecting memory dump depends on the
setting Enable automatic module start . If the setting Enable automatic module
start is disabled, the CPU module does not become the duplex state automatically.

The CPU module changes to simplex state until the completion of writing memory
dump image. Therefore, please note that it takes a longer time than usual to be
duplex state.
(Example: When the size of dump file which is saved is 96GB, it takes about 120
minutes.)

If you shutdown the system while collecting memory dump, the collecting is failed.

If installed memory size is greater than 32GB, there are precautions. Refer to
Chapter 1 (6.1.4 The installed memory size which exceeds 32GB) in Installation
Guide (Windows).
