Table 7-1 Triggers For Collecting Memory Dump - Hitachi HF-W2000 35 User Manual

7. MAINTENANCE ACTIONS
7.2 Memory Dump Collecting Feature
When any of the triggers in Table 7-1 occurs, the Equipment saves the system memory
contents into a file (memory dump file). At this time, a blue screen appears with a STOP
error code. You can troubleshoot the error by analyzing the contents of this memory dump
file. For details of the STOP error code, see Section 6.2, "STOP Error Code".

STOP error
(1) Memory dump setup for Microsoft® Windows®
One type of memory dump file is selectable among the three options in the "System
Properties" window opened from Control Panel. Of these options differentiated by
the range of data, Complete Memory Dump (factory-set default) is recommended.
 Complete Memory Dump: The entire contents of system memory are saved. The
Boot Volume* needs to be allocated to accommodate a paging file that amounts to
physical memory size + 1 MB.
 Kernel Memory Dump: Only the contents of kernel memory are saved. The Boot
Volume* needs to be allocated to accommodate a paging file that amounts to one
third of physical memory size.
 Small Memory Dump: Only necessary minimum memory contents for identifying
the cause of STOP error on the Equipment are saved. The Boot Volume* needs to
be allocated to accommodate a paging file that amounts to at least 2 MB.
* "Boot Volume" means the volume containing Windows® and its support files.
< NOTE >
Although Complete Memory Dump is factory-set on the Equipment with
Windows® 7 preinstalled, once this default setting is changed to any other type of
memory dump, you cannot restore the setting to Complete Memory Dump via the
"System Properties" window. For how to restore the setting under Windows® 7, see
(2) (b) of Subsection 7.3.5, "Various setup procedures relating to memory dump".
In the "System Properties" window, you can also set up virtual memory and automatic
restart after collection of memory dump. For the procedures of these settings, see
Subsection 7.3.5, "Various setup procedures relating to memory dump".

Table 7-1 Triggers for Collecting Memory Dump

Explanation
Press the RESET switch or send a remote reset signal to the external
control port RMTRESET when the CPU locked, and memory dump
will be collected.
Note: Do not send two or more remote set signals to the RMTRESET
port consecutively. Such consecutive input will cause the Equipment to
be unable to collect the memory dump.
At the occurrence of a severe hardware failure in the Equipment (e.g.,
uncorrectable memory error or PCI bus parity error), NMI
(non-maskable interrupt) is automatically generated and memory dump
collection is triggered.
At the occurrence of a severe error in the kernel of Microsoft®
Windows®, memory dump collection is triggered.
