Description
LPAR's memory dump is enabled regardless of the type of guest
OS.
The guest memory dump collection command as an HVM
management command is executed on the LPAR manager
management server.
External FTP server specified by the guest memory dump
collection command (The server that executes the guest memory
dump collection command is also available.)
Memory dump data are transferred from the LPAR manager
machine to the external FTP server through the management LAN.
Dump data file is created by the LPAR manager machine, and the
file is transferred to the external FTP server using the FTP protocol.
The dump data format conforms to the Niko2Dump format.
Binary format file of dump data based on the dump data format
above
gmdP#L#-YYMMDD-hhmmss-nnn.dat
(Note) P#: Partition number: P0 to P7
L#: LPAR number: L01 to L60
YYMMDD: Collection date (in the order of year (2 digits), month (2
digits), and day (2 digits))
hhmmss: Collection time (24-hour notation in the order of hour (2
digits), minute (2 digits), and second (2 digits))
