Loading a STREAMS Module at Kernel

To load a STREAMS module at kernel, first become root:

system% su
Password:
system#

To determine whether you are running a 32-bit Solaris or 64-bit Solaris system, use the isainfo(1) utility as follows:

system# isainfo -v
	64-bit sparcv9 applications
	32-bit sparc applications
	system#

If the command returns this information, you are running the 64-bit Solaris system. If you are running the 32-bit Solaris system, the utility shows the following:

system# isainfo -v
	32-bit sparc applications
	system#

Use modinfo(1M) to be certain that your system has not already loaded the STREAMS module:

system# modinfo | grep eucu8modulename

If the STREAMS module, such as eucu8, is already installed, the output will look as follows:

system# modinfo | grep eucu8
89 ff798000  4b13  18   1  eucu8 (eucu8 module)
system#

If the module is already installed, you don't need to load it. However, if the module has not yet been loaded, use modload(1M)as follows:

system# modload /usr/kernel/strmod/eucu8modulename

This loads the 32-bit eucu8 STREAMS module at the kernel, so you can push it onto a Stream. If you are running the 64-bit Solaris product, use modload(1M) as follows:

system# modload /usr/kernel/strmod/sparcv9/eucu8

The STREAMS module is installed at the kernel, and you can now push it onto a Stream.

To unload a module from the kernel, use modunload(1M), as shown below. In this example, the eucu8 module is being unloaded.

system# modinfo | grep eucu8
89 ff798000  4b13  18   1  eucu8 (eucu8 module)
system# modunload -i 89
