Overview of the DLKM commands
The “km” commands can be found in the directory /usr/sbin
kminstall(1M)
Add/remove/update a kernel module. kminstall(1M) adds or removes the module’s
subsystem code, master and system file.
Removing the krm module:
# kminstall -d krm
# kmsystem -q krm
kmsystem: Invalid module, subsystem or driver name : krm
# cat /stand/system.d/krm
cat: Cannot open /stand/system.d/krm: No such file or directory
Adding the krm module again:
# kminstall -a krm
kminstall: Local directory must contain a mod.o file
# cd /etc/opt/resmon/lib/krm
# kminstall -a krm
