class may also be the word all
, in which case all classes are added to the appropriate list. (The effect of
adding all classes to the included class list is to force full crash dumps under all circumstances. The
effect of adding all classes to the excluded class list is to disable crash dumps.)
Persistent Dump Devices
To mark the dump devices as persistent, there are two configuration modes available.
config_crashconf_mode
In this mode
crashconf (this command) and
crashconf() (see crashconf (2)) are the only mechan-
isms available to mark dump devices as persistent. Logical volumes marked for dump using
lvlnboot
or vxvmboot and devices marked in /stand/system
for dump will be ignored during boot-up. This is
the preferred method for dump device configuration and will be used from this HP-UX release onwards.
This mode can be enabled using the
-s
option. VxVM stores extent information of persistent dump logi-
cal volumes in lif (see lif (4)). Up to ten VxVM logical volumes can be marked persistent. The logical
volumes which are not part of the root volume group cannot be configured as persistent dump devices.
config_deprecated_mode
The logical volumes marked for dump using
lvlnboot
or vxvmboot and devices marked in
/stand/system
for dump will be configured as dump devices during boot-up. Devices marked as per-
sistent, using
crashconf -s, will be ignored during boot-up. Marking devices using
lvlnboot,
vxvmboot, and /stand/system
will be obsoleted in the next HP-UX release. This mode is deprecated
in this release and will be obsoleted in the next HP-UX release. This is the default mode for dump and
can be enabled using the
-o option also.
Persistent dump devices information is maintained in the kernel registry services, (KRS, see krs(5)).
Options
The following are valid options for
crashconf:
-a Apply the dump devices in /etc/fstab to the current list of crash dump devices:
• add these devices to the current list; or
• (with
-d) delete them from the current list; or
• (with -r) replace the current list.
This is in addition to the dump devices specified on the command line. See fstab (4) for infor-
mation on the format of
/etc/fstab.
-c cmode Specify the compression mode: either ON or OFF. If the system is not able to identify enough
processing resources to do compressed dump, a warning message will be issued.
-d Delete all dump devices mentioned on the command line from the current list of crash dump
devices. If the -a option is also specified, then dump devices in /etc/fstab will also be
deleted. However, the dump device list cannot be made empty. This option cannot be used
with the -r (replace) option.
-e classes Add the specified classes to the list of excluded classes; or if -r
is used, replace the list of
excluded classes with the specified classes. If any of the specified classes are present in the
current included class list, they will be removed from the included class list.
-i classes Add the specified classes to the the list of included classes; or if -r is used, replace the list of
included classes with the specified classes. If any of the specified classes are present in the
current excluded class list, they will be removed from the excluded class list.
-l Display the lunpath hardware path (see intro (7)) through which the device is currently
configured. The lunpath hardware path is not displayed if the device is offline. This path
may change in cases of path failover or device reconfiguration.
-o Switch dump configuration mode from config_crashconf_mode to
config_deprecated_mode. This option will be obsoleted in the next HP-UX release.
The -o and -s options are mutually exclusive. The extent information for persistent VxVM
dump logical volumes will continue to be present in lif (see lif (4)).
-p pmode Specify the concurrency mode: either ON or OFF. Depending on the availability of addi-
tional memory and the configuration of dump devices, the system may fall back to non-
concurrent dump mode and a warning message will be issued. Currently supported only on
Integrity systems.
-r Specify that any changes should replace, rather than add to, the current configuration.
Thus, if devices or -a are specified, the current crash dump device list is replaced with new
