NAME
livedump - initiates, configures, and stops Live Dump
SYNOPSIS
/sbin/livedump
[-aqbt][-m minfree ] [-s chunksize][
-i class][-e class][-p path]
[
-c livedumpmsg][-d action]
DESCRIPTION
The
livedump utility is used to query and modify configurable parameters (pageclass, minfree, chunk-
size, 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 administra-
tor privileges.
Options
-a Start the Live Dump daemon.
-d action Start or stop a Live Dump. The following are valid usages:
-d START 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.
-b 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.
-q 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.
