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