discover-modprobe(8) System Manager's Manual discover-modprobe(8)NAME
discover-modprobe -- kernel module loading using discover(1)SYNOPSIS
discover-modprobe [-n] [-v]
Description
discover-modprobe loads kernel modules identified by discover. It will typically be invoked automatically at boot time.
Options-n Echo the modprobe invocations instead of running them.
-v Be verbose.
Files
/etc/discover-modprobe.conf
This configuration file defines the types of modules to load by default, and specific modules not to load.
/var/lib/discover/crash
A crash file written and erased each time discover-modprobe attempts to load a module. If the file lingers, the computer is
assumed to have crashed while loading that module, and the module name is added to discover-modprobe.conf as a module to skip in
the future.

aoe-interfaces - restrict aoe driver to specified network interfaces
SYNOPSIS
aoe-interfaces [dev1] [dev2 ...]
aoe-interfaces -c
DESCRIPTION
The aoe-interfaces command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic on all but the specified network interfaces. It
is analogous to the aoe_iflist module load option.
If neither the aoe_iflist module load option nor the aoe-interfaces command are used, the aoe driver will use any network interface for AoE
traffic. Using aoe-interfaces to limit AoE to only trusted networks prevents the case where a rogue AoE target appears on a public net-
work, diverting data from the legitimate AoE target. Such an imposter target effectively corrupts the data on the legitimate target.
If the aoe driver is a module, then calling aoe-interfaces without arguments will display the current interfaces list. If it hasn't been
set then the output will be blank.
It's good to run the aoe-discover command after setting the AoE interfaces list.
OPTIONS -c The -c flag will clear the interface access list, permitting any interface to be used.
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
nai:~# aoe-interfaces
eth0 eth3
