.TH aoe-discover 8
.SH NAME
aoe-discover \- tell aoe driver to discover AoE devices
.SH SYNOPSIS
.nf
.B aoe-discover
.fi
.SH DESCRIPTION
The
.I 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.  
.PP
If the 
.I 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.
.PP
It's good to run the 
.I aoe-discover
command after running \fIaoe-interfaces\fP.
.SH EXAMPLE
In this example, the root user on a host named
.I nai
loads the aoe module with only eth0 allowable for AoE traffic.  After
remembering that shelf 7 is on eth3, this
sysadmin uses 
.I aoe-interfaces
to add eth3 to the list of allowable network interfaces and then
calls
.I aoe-discover
to ask the aoe driver to look for new AoE devices.
