When you go into "smitty etherchannel", change/show, choose your etherchannel, look at the "Mode". You can have "standard" which means it only uses the secondary adapter when the first one loses it's connection. When this happens, you'll see something like "etherchannel failover" in the errpt. You'll see another error in the errpt when it goes back over to the primary adapters... something like "etherchannel restored" or "ether path restored"... I can't remember for sure, but you do see an event everytime it changes.

You can also set "Mode" to "round_robin" which means that it sends so many packets through one adapter and then so many packets through the other adapter and keeps switching back and forth. All this does is split your network traffic between the two adapters.

Both settings are good for redundancy. It just depends on how/if you want your data split between the two adapters.

I have personally physically removed adapters and plugged in other ones, always making sure at least one has a physical connection to the switch, and AIX handled it just fine. It recorded a bunch of errors in the errpt, but that was expected.a

NAME

       scconf_transp_adap_ibd - configure the InfiniBand (ibd) transport adapter

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       You can configure ibd adapters as cluster transport adapters. These adapters can only be used with transport type dlpi.

       The ibd adapter connects to an InfiniBand transport switch. The connection is made through a transport cable.

       When  the  endpoints of the transport cable are configured by using scconf, scinstall, or other tools, you are asked to specify a port name
       on the transport switch. You can provide any port name, or accept the default, as long as the name is unique for the switch.

       The default is to set the port name to the node ID that hosts the adapter at the other end of the cable.

       There are no user-configurable properties for cluster transport adapters of this type.
