aoe-discover

The aoe-discover command tells the aoe driver to discover ATA over Ethernet (AoE) devices on the network.  All network interfaces will be probed with a AoE config query broadcast.  

If the aoe-interfaces command has limited the allowable network interfaces, only devices discovered via allowable interfaces will become available.  The default is to make available all AoE devices found on all accessible ethernet networks.

It's good to run the aoe-discover command after running aoe-interfaces.

In this example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic.  After remembering that shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then calls aoe-discover to ask the aoe driver to look for new AoE devices.

nai:~# modprobe aoe aoe_iflist="eth0"
nai:~# aoe-stat
   e10.9            eth0              up
nai:~# aoe-interfaces eth0 eth3
nai:~# aoe-discover
nai:~# aoe-stat
    e7.0            eth3              up
    e7.1            eth3              up
    e7.2            eth3              up
    e7.3            eth3              up
    e7.4            eth3              up
    e7.5            eth3              up
    e7.6            eth3              up
    e7.7            eth3              up
    e7.8            eth3              up
    e7.9            eth3              up
   e10.9            eth0              up
