livedump — initiates, configures, and stops Live Dump


/sbin/livedump [-aqbt] [-m minfree ] [-s chunksize] [-i class] [-e class] [-p path] [-c livedumpmsg] [-d action]


The livedump utility is used to query and modify configurable parameters (pageclass, minfree, chunksize, etc.). It is also used to enable/disable Live Dump feature and to start/stop Live Dump. See livedump(5) for details on the configurable parameters.

Live Dump saves the operating system state to the existing directory that is specified by path.

Invoking the livedump command with no arguments displays the current Live Dump configuration and can be used by ordinary users. However, using options along with the command requires administrator privileges.



Start the Live Dump daemon.

-d action

Start or stop a Live Dump. The following are valid usages:


Initiate a Live Dump.

-d STOP {-1|SID_ANY}

STOP -1 or STOP SID_ANY stops a currently running Live Dump, kernel or user initiated.

-d STOP sid

Stop a Live Dump identified by the particular session id, sid.

The -d STOP options should not be used along with any other options. See livedump(5) for more details on sid.


Initiate Live Dump in blocking mode. To be used with -d START option. See livedump(5) for details on blocking invocation.

-c livedumpmsg

Store Live Dump message in the INDEX file. Should be used along with -d START option.

-e class

Exclude the page class specified by class from the Live Dump. If both -i and -e options are specified on the command line, -i option will override the page classes set with -e option.

-i class

Include the page class specified by class in the Live Dump. This option has precedence over -e option.

-m minfree

Specify the amount of space left free upon completion of Live Dump. Default value is zero. The default unit is Bytes (b or B). It also supports Kilo (K or k), Mega (M or m), Giga (G or g), and Tera (T or t) unit.

The specified minfree can be followed by a b or B or space. The following all specify a minfree of 3 giga bytes:

livedump -m 3Gb

livedump -m 3GB

livedump -m 3G

If Live Dump detects that the free disk space has fallen below the minfree value, it stops saving the dump. The saved dump may not be debuggable.

-p path

Specify the directory to save the Live Dump. If this option is not specified, then /var/adm/crash is used as default directory to save the dump.


Stop the Live Dump daemon. This option should not be used in conjunction with other options.

-s chunksize

Specify the size of a Live Dump image file. Value has to be between 1G and 2G. The default unit is Bytes (b or B). It also supports Kilo (K or k), Mega (M or m), Giga (G or g), and Tera (T or t) unit.

The specified chunksize can be followed by a b or B or space. The following all specify a chunksize of 1 giga bytes:

livedump -s 1Gb

livedump -s 1GB

livedump -s 1G


Use the Live Dump configuration specified on command line only for the particular Live Dump invocation. If specified without this option, the Live Dump configuration is made default till next boot. This option should be used along with the -d START option.


Upon exit, livedump returns the following values:


Live Dump was configured/saved successfully.


Live Dump could not be saved; invalid options were specified in the command line.


The Live Dump feature was developed by Hewlett-Packard.

Live Dump startup file
