Dear hell_angel,

yes you also need to configure the iSCSI initiator (i.e. the iSCSI "client" software on the server) for MPIO.
Please refer to the following good resources:

IBM System Storage N series MPIO Support—Frequently Asked Questions
http://www.redbooks.ibm.com/redpapers/abstracts/redp4213.html

On NOW.netapp.com, which however requires you have registered as a NetApp customer additional informaiton can be found (please consult with your IBM partner, for the IBM equivalent resources):

How to setup iSCSI MPIO on Windows 2003 using Microsoft multipathing

SAN/IP SAN Best Practices Index - Multipathing - iSCSI
http://now.netapp.com/NOW/knowledge/docs/bpg/san_ipsan/multipathing_iscsi.shtml

Best practice is on the server side, not to create a "vif" (i.e. trunk/channel/team), but rather have two "independent" NIC's with eahc their seperate IP.
The iSCSI initiator, then use these two NIC's for MPIO.
On the controller side, it's ok to use vif for the iSCSI traffic.
