ifconfig , ifdown, ifup
hi there

the ethernet wire was out of the pc when the system started.

Code:
#ifconfig
#ifconfig -a

i did not get any ip for eth0.
i plug the cable into the pc

Code:
#ifdown eth0
#ifup eth0

now the ip address is assigned to eth0

Question is : IS this right way to bring ethernet down and then bring up in case of any problem with NIC?

thanks

aoe-discover

aoe-discover(8) 					      System Manager's Manual						   aoe-discover(8)

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.

	      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
