modunload(1M) System Administration Commands modunload(1M)NAMEmodunload - unload a module
SYNOPSISmodunload-i module_id [-e exec_file]
DESCRIPTIONmodunload unloads a loadable module from the running system. The mod‐
ule_id is the ID of the module as shown by modinfo(1M). If ID is 0, all
modules that were autoloaded which are unloadable, are unloaded. Mod‐
ules loaded by modload(1M) are not affected.
OPTIONS
The following options are supported:
-e exec_file Specify the name of a shell script or executable image
file to be executed before the module is unloaded. The
first argument passed is the module id (in decimal).
There are two additional arguments that are module spe‐
cific. For loadable drivers, the second argument is the
driver major number. For loadable system calls, the
second argument is the system call number. For loadable
exec classes, the second argument is the index into the
execsw table. For loadable filesystems, the second
argument is the index into the vfssw table. For load‐
able streams modules, the second argument is the index
into the fmodsw table. For loadable scheduling classes,
the second argument is the index into the class array.
Minus one is passed for an argument that does not
apply.
-i module_id Specify the module to be unloaded.

The modunload command is often used on driver modules to force the sys‐
tem to reread the associated driver configuration file. While this
works in the current Solaris release, it is not the supported way to
reread the configuration file and is not guaranteed to work in future
releases. The supported way for rereading driver configuration file is
through the update_drv(1M) command.
