dumpadm - configure operating system crash dump

SYNOPSIS

/usr/sbin/dumpadm [-nuy] [-c content-type] [-d dump-device]

[-m mink | minm | min%] [-s savecore-dir]

[-r root-dir] [-z on | off]

The options include:

A: -d dump-device

Modify the dump configuration to use the specified dump device.

B: -s savecore-dir

Modify the dump configuration to use the specified directory to

save files written by savecore.

D: -m mink | minm | min%

Create a minfree file in the current savecore directory indicating

that savecore should maintain at least the specified amount of free

space in the file system where the savecore directory is located.

E: -z on | off

Modify the dump configuration to control the operation of savecore on reboot. The options are on, to enable saving core files in a compressed format, and off, to automatically uncompress the crash dump file. The default is on, because crash dump files can be very large and require less file system space if saved in a compressed format.
