So you do the ifconfig to lo after iscsi is setup and logged in right? 
Is the ip address different from what you originally logged into? I mean 
originally you did

iscsiadm -m node -T some_tagret -p original_ip -l

then when you do the ifconfig it is a new_ip, but the iscsi tools think 
you want to still connect to original_ip  so you get the connect failed 
errors and eventually the replacement/recovery timeout errors.

What you would have to do is create a session to original_ip, then 
create a new session to new_ip, and if you do not want to see IO errors 
then you would use dm-multipath over both sessions and that would handle 
switching from the old path to the new path for you.
