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.
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

aoecfg - manipulate AoE configuration strings
SYNOPSIS
aoecfg [-c cmd] [-s cfgstr] [-t timeout] [shelf slot] [netif]
DESCRIPTION Aoecfg(8) sends AoE configuration commands that control the retrivial, conditional or unconditional setting of AoE configuration strings.
Since configuration happens before the MAC address of the target is known, the packet is broadcast. AoE targets with a matching shelf and
slot respond. Since the default shelf and slot are the wildcard values 0xffff and 0xff, with no arguments aoecfg(8) will return configura-
tion strings from all targets visible on the default interface, eth0.
OPTIONS -c cmd specify the AoE configuration command. The default is read. The available commands are
read Read the server config string without performing any test and respond.
test Respond only if the specified string exactly matches the server configuration string.
prefix Respond only if the specified string is a prefix of the server configuration string.
set If the current server config string is empty, set the server config string to the argument string and respond. If the current server
config string is not empty, return a response with Flags bit E set and Error set to 4.
fset Force set the server config string to the argument string and respond.
-s cfgstr
specify the config string.
-t timeout
specify the timeout in seconds. The default is no timeout. If neither the shelf nor the slot are specified, aoecfg(8) will exit
after the first result. Otherwise, aoecfg(8) will exit only after the timeout has expired since it does not know how many
responses to expect.
shelf slot
specify the shelf and slot used in the query. If unspecified, they default to broadcast.
netif specifiy the network interface. The default is eth0.
