Compressed Dump

Compressed Dump White Paper, Version 1.3

portions of the physical memory image and metadata
describing which memory pages were dumped and
which were not. sources or destinations of this type
should be specified as the pathname to a crash directory.
PARDIR (Version 3) This format is used in HP-UX Release 11i
Version 2.0 and later. It is very similar in structure to the
CRASHDIR format in that it consists of a crash.n direc-
tory containing an INDEX file, the kernel and all dynami-
cally loaded kernel module files, and numerous
image.m.p files, each of which contain portions of the
physical memory image and metadata describing which
memory pages were dumped and which were not. In
addition to the primary INDEX file, there are auxiliary
index files, that contain metadata describing the image
files containing the memory pages. This format will be
used when the dump is compressed. See crashconf(1M).
Other formats, for example tape archival formats, may be added in the future.
When the source and destination are different types of files - for example, when
source is a directory and destination is a pair of plain files - both must be specified.
Options
-q (Quiet) Disables the printing of progress messages.
Warning and error messages are still printed.
-v version Specifies the version of the destination format. Allowed
values are COREFILE, COREDIR, CRASHDIR, PARDIR,
0, 1, 2 or 3. Also allowed is the keyword CURRENT,
which specifies that the destination format should be the
same as the current source format. CURRENT is the
default if -v is not specified. If the destination format is
PARDIR, then the source format should also be PARDIR.
Conversion to PARDIR from older formats is not sup-
ported.
RETURN VALUE
Upon exit, crashutil returns the following values:
0 The operation was successful.
1 The operation failed, and an appropriate error message was
printed.
EXAMPLES
An HP-UX 11.00 crash dump was saved by savecrash(1M) to /var/adm/crash/
crash.2. The -p flag was specified to savecrash, specifying that only those portions
of the dump which were endangered by swap activity should be saved; the rest are
