DESCRIPTION
The livedump utility is used to query and modify configurable parameters such as class (page class),
minfree , chunksize , path, and livedumpmsg . It is also used to enable/disable the
Live Dump feature
and to start/stop
Live Dump. See livedump (5) for details on the configurable parameters.
NOTE: The
Live Dump feature is currently available only on Itanium(R)-based platforms.
Live Dump saves the operating system state to the existing directory that is specified by path .
By default, the
Live Dump feature is disabled. Follow these steps to enable
Live Dump:
• Set the value of
LIVEDUMP_ENABLED
to 1 in the file
/etc/rc.config.d/livedump
.
• Start the
Live Dump kernel daemon:
/sbin/init.d/livedump start
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 system
administrator privileges.
Options
-a Start the Live Dump daemon.
-d action Start or stop a Live Dump. The following valid usages are:
-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 .
NOTE: 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 the -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 the -d
START option.
-e class Exclude the page class specified by class from the Live Dump. If both the -i and -e
options are specified on the command line, the -i option will override the page classes
set with the -e option.
-i class Include the page class specified by class in the Live Dump. This option has precedence
over the -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
