OS event log
An event log is the data required for investigation in Windows OS. Events that
have occurred inside the OS are recorded in the event log in chronological order.
The "Event Viewer" is provided as a management tool for referencing the event
log. In the Windows Start menu, click Start > Administrative Tools > Event
Viewer. For details, see the Event Viewer's help.
Event types include information, warnings and errors. It has been confirmed that
events are temporary or known instances even if they are errors or warnings. In
case of an error or a warning, see Hitachi Compute Rack 210H/220H Windows
Installation Guide or the manual that comes with the software being used.
For general Windows instances, verify the support technical information
(Knowledge Base) of Microsoft Corporation.


STOP message and memory dump
If the Windows OS has been trapped in a critical state for some reason, a blue
screen appears and a STOP message is displayed. At this time, Windows can
save the STOP message information in a dump file. This is referred to as a
memory dump.
If Windows is hung up, the cause of a failure can be narrowed down by analyzing
the memory dump.
The following three types of memory dumps are available:
Minimum memory dump (64 KB)

Kernel memory dump

Full memory dump

The full memory dump is effective in fault investigation. The other dumps are
extremely difficult to analyze because of less information contained therein.
The following conditions are required for full memory dump. When you configure
partitions, be aware of acquisition of a full memory dump during system
construction.
A page file is in the Windows-installed drive (C drive).

A page file is larger than physical memory installed + 400 MB.

Free space for a dump file should exist in the C drive.

For details on the setting of a page file (virtual memory), see Windows help.
