This means your server will have downtime.
I thought the best practice was to take down one node of the failover group, upgrade that node, restart the node, re-establish the failover grouping (allow the failover re-sync to occur) and then take down the other failover node.

Using this process, no impact on the iSCSI initiators (servers access iSCSI) would be seen, since the disk access would follow the failover path.
