 How to use the guest memory dump function
For the basic usage of HVM management commands that are essential when using the
guest memory dump function, see the HVM Management Command (HvmSh) User's
Guide. For how to use commands related to the guest memory dump function in HVM
management commands, see "Starting Guest Memory Dump," "Stopping Guest Memory
Dump," and "Acquiring Guest Memory Dump Progress" in the "LPAR manager Interface
Individual Specifications" of the HVM Management Command (HvmSh) User's Guide.
 Precautions
Follow the precautions described below when using the guest memory dump function.
After guest memory dump is started, all logical CPUs of the target LPAR stop, and

logical server processing is not restarted. For this reason, use this function only
when logical server processing can no longer be continued (such as when a
logical server error has occurred).
Description
The following three regions used by the OS are provided for
memory dump within the memory area allocated to the target LPAR
(No memory area in the LPAR can be specified.)
DOS region: 00_0000_0000 to 00_0009_FFFF
Low memory: 00_0010_0000 to 00_7FFF_FFFF
High memory: 01_0000_0000 to MMCFG - 1
(Note) These regions are the same as those for Niko2Dump of
Basic.
One LPAR / LPAR manager machine (Another dump data
collection request to the same LPAR manager machine cannot be
accepted during memory dump even to another LPAR of the same
LPAR manager machine.)
Memory dump data can be collected only when the target LPAR is
activated.
The guest memory dump function works as follows in relation to the
guest software program:
・ Memory dump data can be collected regardless of the operation of
the guest software program (even when it can no longer operate
due to an error during operation).
