The aoe kernel driver allows Linux to do ATA over Ethernet. In addition to the aoe driver, there is a collection of helpful programs that operate outside of the kernel, in "user space". This collection of tools and documentation is called the aoetools, and may be found at http://aoetools.sourceforge.net/.
Current aoe drivers from the Coraid website are bundled with a compatible version of the aoetools. This HOWTO may make reference to commands from the aoetools, like the aoe-stat command.
By default, the aoe driver will use any local network interface available to reach an AoE target. Most of the time, though, the administrator expects legitimate AoE targets to appear only on certain ethernet interfaces, e.g., "eth1" and "eth2".
Using the aoe-interfaces command from the aoetools package
allows the administrator to limit AoE activity to a set list of
ethernet interfaces.
This configuration is especially important when some ethernet interfaces are on networks where an unexpected AoE target with the same shelf and slot address as a production AoE target might appear.
Please see the aoe-interfaces manpage
for more information.
At module load time the list of allowable interfaces may be set with the "aoe_iflist" module parameter.
modprobe aoe 'aoe_iflist=eth2 eth3'
