"Etherchannel" is IBMs name for bundling several IP interfaces together to one. You can do that either for failover purposes or for load balancing. The process is: you first create the physical interfaces (entX, entX+1, ...), don't give them any IP address or configure them otherwise, then create an "Etherchannel" device from them. You probably want to follow the SMIT panels for this, they are pretty self-explanatory.

Issue a

Code:
lsdev -Cc adapters

which should show you your cards as well as by which device name they go by.

I hope this helps.

Thanks that does help. I guess what still confuses me is I don't know if I can configure Etherchannel or not with the iSCSI cards. When I show the adapters I do have ent0 and ent1 and then ics0 and ics1. Is it possible that ent0 and ent1 are part of the iSCSI cards? They are listed as "10/100/1000 Base-TX PCI-X Adapter" and I don't have any additional ethernet ports beyond the integrated ports and the iSCSI ports that I added.

ISCSI.CONF(5)							File Formats Manual						     ISCSI.CONF(5)

NAME

       iscsi.conf - iSCSI Target and LUN configuration

SYNOPSIS

       /etc/iscsi.conf

DESCRIPTION

       This manual page describes the format of the /etc/iscsi.conf file. This file is a simple text file that iscsid(8) uses to locate iSCSI tar-
       get devices and LUNs.  Comments are marked by lines beginning with '#'.

       Available entries include:

       DiscoveryAddress=<address>
	      IP address or hostname to use for target discovery.  A TCP port number may be specified by appending a colon followed  by  the  port
	      number. This entry must start in the first column, and must not contain any whitespace.

       TargetIpAddr=<address>
	      A synonym for DiscoveryAddress.

       Username=<user>
	      Specify  the  authentication user.  If this entry precedes all DiscoveryAddress entries, it serves as the default.  If this entry is
	      indented under a DiscoveryAddress entry, it specifies the user for all targets discovered at that IP address.

       Password=<pass>
	      Specify the authentication password for the previously listed iSCSI If this entry precedes all DiscoveryAddress entries,	it  serves
	      as  the default.	If this entry is indented under a DiscoveryAddress entry, it specifies the user for all targets discovered at that
	      IP address.

EXAMPLE

       # set the default user and password
       Username=alice
       Password=nty57nbe

       # targets at this address will use the default Username and Password
       DiscoveryAddress=192.168.10.94

       # targets at this address will use the Username and Password below
       DiscoveryAddress=192.168.10.95
	   Username=beatrice
	   Password=93fdgc20
