livedump(1M) livedump(1M)

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.

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

-t Use the Live Dump conﬁguration speciﬁed on the 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.

Example : livedump -t -i USTACK -d START

RETURN VALUE

Upon exit, livedump returns the following values:

0 Live Dump was conﬁgured/saved successfully.

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