You are correct the Network Admin Guide for 8.1 Cluster-Mode does not state if iSCSI LIF's can or cannot be migrated.
To answer your question.... If you are looking to create a new path for the client path to access a LUN then you will need to create a new LIF on the node in question. This is indirectly implied in Page 45 of the guide "Failover groups do not apply in a SAN iSCSI or FC environment."
We will look to add this information in the next update to the guides.
I have netapp cluster mode simulator and have configured one node on this. I created ISCSI LIF using a STATIC ip( iscsi_lif) but ISCSI initiator utility on widnows 7 on my laptop is unable to find it. I also can not ping it.
Please tell me why iSCSI lif is unpigable and how to resolve it
