If you have only one VIO on each blade, then SEA holds no good, coz it won't failover. If you have two VIOS, then only you are good to go for SEA.

Now, considering you have two VIOS, we have to figure out which virtual adapter (out of the 4) is your primary adapter and which is control channel adapter. You can check the profile (of virtual adapter) if a adapter has been check as access external network, and given a trunking priority then it is your primary adapter, for control channel adapter you WONT select access external network, and most shops give it a vlan no of 99 (purely environment based, so such standard), so as to distinguish control channel adapter from others.

You cannot use smitty (in rksh), you have to use mkdev command to create SEA.
$ mkvdev -sea "real adapt" -vadapter "primary virt adapt" -default "primary virt adapt" -defaultid "PVID" -attr ha_mode=auto ctrl_chan="control channel adapt"

Hope this helps.
