Explanation:
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 defaultis on, because crash dump files can be very large and require less file system space if saved in a compressed
format.
