HP-UX Reference (11i v2 04/09) - 1M System Administration Commands A-M (vol 3)

crashconf(1M) crashconf(1M)

-r Speciﬁes that any changes should replace, rather than add to, the current conﬁguration. Thus, if

devicesor -a are speciﬁed, the current crash dump device list is replaced with new contents; if

classes are speciﬁed with -e

, they replace the list of currently excluded classes, and if classes are

speciﬁed with

-i, they replace the list of currently included classes.

-t When used with the -i, -e

or -c options, sets the dump tunables alwaysdump , dontdump and

dump_compress_on respectively, to make the changes persistent across system reboots.

-v Displays the current crash dump conﬁguration. This is the default option if no arguments are

speciﬁed. If any changes to the current conﬁguration are speciﬁed on the same command line as

-v,

the conﬁguration will be displayed after the requested changes are made.

RETURN VALUE

Upon exit,

crashconf returns the following values:

0 Success.

1 The requested conﬁguration changes could not be made.

WARNINGS

On systems running VxVM 3.5, the swap volumes to be conﬁgured for system crash dumps should be

created with the usage type as

swap during the creation of the swap volume. Not doing so will cause

dump corruption. You could use the -U option of vxassist (1M) to do the same.

The output of

crashconf is not designed to be parsed by applications or scripts, but only to be read by

humans. The output format may change without notice. Applications which require crash dump

conﬁguration information should retrieve that information using pstat (2).

Dump devices created by lvcreate (1M) must be contiguous (

-Cy option) with bad block relocation turned

off (-rn option).
