# aoe-discover(8)

tell aoe driver to discover AoE devices

## NAME

aoe-discover - tell aoe driver to discover AoE devices

## SYNOPSIS

```
aoe-discover
```

## DESCRIPTION

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*.

## EXAMPLE

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.
