What you're looking for is called an ifgrps. They actually can't cross controllers. So you could bundle e0a and e0b on the same controller together. During a failover the IPs that use that ifgrp would move to the partner and data would continue to be served out.
are you thinking like a cisco device were you have to run something like "copy run start" to make sure it boots OK the next time? - There's no need for this type of action on netapp.
sorry about that, give this a look over. (been a while since I had to build a new 7mode system!) yeah, you need to copy the same command into the etc/rc file
