3. (PA-RISC only) allows you to chose an alternate device to which the Monitor dump is written. The
alternate device must contain the pre-allocated file /stand/vpmon.dmp. The file vpmon.dmp is
automatically created in /stand of a partition’s boot disk by the vPars startup script.

5. hard resets the current hard partition.

7. boots the specified virtual partition for crash processing
If you chose to invoke a virtual partition for crash processing or to examine memory contents, you will be
returned to this menu after those actions are completed (assuming no new crash event is encountered).
Directory Location and Filenames
On PA-RISC, the Monitor dump is written to the pre-existing file called /stand/vpmon.dmp.
On Integrity, the Monitor dump is written to a file called vpmon.dmp that is created in the EFI partition of the
Monitor boot disk. The file will be at fsN:/efi/hpux/vpmon.dmp.
When the virtual partition that owns the Monitor boot disk is booted, the following files are created
automatically in /var/adm/crash/vpar (where n is a number representing the nth occurrence of a dump):
NOTE On PA-RISC, the file /stand/vpmon.dmp is a special file. Do not delete, move, rename, or
modify this file. If you need to look at the contents of the Monitor dump file, use the
vpmon.dmp.n file located in /var/adm/crash/vpar.
Monitor Dump Analysis Tool
Because the vPars Monitor is not a HP-UX kernel, you cannot use a kernel dump analysis tool to examine a
Monitor dump file. Contact your HP Support Representative to analyze the Monitor dump file.
Kernel Dumps
If a TOC (transfer of control) or HPMC (High Priority Machine Check) for the entire hard partition is
generated, a kernel dump will not automatically be saved to /var/adm/crash for those partitions that have
not previously had a kernel dump occur. You can save their dumps to /var/adm/crash by performing the
following on each of those virtual partitions:
Step 1. (11i v2 only) For HP-UX 11i v2 and therefore vPars A.04, the savecrash processing has changed.
Instead of copying the kernel file that was in use during the crash, the directory
/stand/crashconfig is copied. Therefore, prior to executing the crashconf and savecrash steps
below, create the /stand/crashconfig directory using
# kconfig -s crashconfig
