NAME
       crashutil - manipulate crash dump data

SYNOPSIS
       version] source [destination]

DESCRIPTION
       copies  and  preserves crash dump data, and performs format conversions
       on it.  Common uses of include:

       ·    Copying portions of a dump that still reside on a raw dump	device
	    into a crash dump directory.

       ·    Converting between different formats of crash dumps.

       ·    Copying crash dumps from one directory, or medium, to another.

       will  write to its destination the crash dump it reads from its source.
       The crash dump format used to write the destination is  specified  with
       if  is  not specified, the destination will have the same format as the
       source.	If no destination is specified, source	is  used;  the	format
       conversion  will be done in place in the source, without copying.  When
       completes successfully, the entire contents  of	the  crash  dump  will
       exist  at  destination;	any  portions  that had still been on raw dump
       devices will have been copied to destination.

       There are three known dump formats:

       (Version 0)   This format, used up through HP-UX 10.01, consists	 of  a
		     single  file containing the physical memory image, with a
		     1-to-1 correspondence  between  file  offset  and	memory
		     address.  Normally there is an associated file containing
		     the kernel image.	sources or destinations of  this  type
		     must  be specified as two pathnames to plain files, sepa‐
		     rated by whitespace; the first is the core image file and
		     the second is the kernel image file.

       (Version 1)   This  format, used in HP-UX 10.10, 10.20, and 10.30, con‐
		     sists of a directory containing an file, the kernel file,
		     and  numerous files, which contain portions of the physi‐
		     cal memory image.	sources or destinations of  this  type
		     should be specified as the pathname to a core directory.

       (Version 2)   This format, used in HP-UX 11.00 and later, consists of a
		     directory containing an file, the kernel and all  dynami‐
		     cally  loaded  kernel  module  files, and numerous files,
		     each of which contain 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.

       (Version 3)   This format is used in HP-UX Release 11i Version 1.0  and
		     later.   It is very similar in structure to the format in
		     that it consists of a directory containing an  file,  the
		     kernel  and  all  dynamically loaded kernel module files,
		     and numerous files, each of which contain portions of the
		     physical  memory image and metadata describing which mem‐
		     ory pages were dumped and which were not.	In addition to
		     the  primary  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
       (Quiet)	Disables the printing of progress messages.
		   Warning and error messages are still printed.

       Specifies the version of the destination format.
		   Allowed  values are 0, 1, 2 or 3.  Also allowed is the key‐
		   word which specifies that the destination format should  be
		   the	same  as the current source format.  is the default if
		   is not specified.  If the destination format	 is  then  the
		   source  format should also be Conversion to from older for‐
		   mats is not supported.

RETURN VALUE
       Upon exit, 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 The 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
       still resident in the raw dump devices.	To save the remainder  of  the
       dump into the crash dump directory, use:

       If  preferred, the completed crash dump directory could be in a differ‐
       ent location — perhaps on another machine via NFS:

       To debug this crash dump using tools which do not understand  the  most
       current	crash dump format, convert it to the older core directory for‐
       mat:

       or the even older "core file and kernel" format:
