Starting Qnet
To start Qnet, load the lsm-qnet.so shared object into the network manager.
The io-pkt* manager is a process that assumes the central role to load a number of shared objects. It provides the framework for the entire protocol stack and lets data pass between modules. In the case of native networking, the shared objects are lsm-qnet.so and networking drivers (devnp-*.so). The shared objects are arranged in a hierarchy, with the end user on the top, and hardware on the bottom.
-
It's possible to run more than one instance of io-pkt, but
doing so requires a special setup.
If you want to start io-pkt*
by hand,
you should slay the running io-pkt* first. - You can have at most one instance of Qnet running on a node, even if you're running more than one instance of io-pkt.
You can start the io-pkt* from the command line, telling it which drivers and protocols to load:
$ io-pkt-v4-hc -d abc100 -p qnet
This causes io-pkt-v4-hc to load the fictitious devnp-abc100.so Ethernet driver and the Qnet protocol stack.
Or, you can use the mount and umount` commands to start and stop modules dynamically, like this:
$ io-pkt-v6-hc
$ mount -Tio-pkt devnp-abc100.so
$ mount -Tio-pkt lsm-qnet.so
To unload the driver, use the ifconfig destroy command.
