Kernel Crash Dump Parameter Summary
The following parameters affect dump operations when a kernel panic occurs and parts
of system memory are dumped to disk.
See also “How to Specify Configurable Parameter Values” on page 13.
Kernel Crash
Dump
alwaysdump Select which classes of system memory pages are to be
dumped if a kernel panic occurs. Manpage: alwaysdump
(5).
Kernel Crash
Dump
dontdump Select which classes of system memory pages are not to be
dumped if a kernel panic occurs. Manpage: dontdump (5).
Kernel Crash
Dump
initmodmax Maximum size of the dump table of dynamically loaded
kernel modules. Manpage: initmodmax (5).
Kernel Crash
Dump
modstrmax Maximum size, in bytes, of the savecrash kernel module
table that contains module names and their locations in
the file system. Manpage: modstrmax (5).
