Ummm, I either do not understand what you mean or it the answer is 
really simple.

When you run iscsiadm by hand if you do

iscsiadm -m discovery -t st -p ip:port

and you get,2 iqn.my_taget
[ipv6 addr],2 iqn.my_taget

Then to log into a specific one you use the -p/--portal argument:
iscsiadm -m nodde -T iqn.my_taget -p,2 -l

If you wanted to set this up so this one is logged into automatically 
set the node.startup setting to automatic. Or if you do not want the 
portal to be logged into automatically set it to manual.

iscsiadm -m node -T targetname -p ip:port --op update -n node.startup -v 

iscsiadm -m node -T targetname -p ip:port --op update -n node.startup -v 

See the README for how to pass in ipv6 addrs.

not yet.

Are you sure you want to map the target to a fixed sd id? What distro 
are you using? What is wrong with their udev naming scheme? Have you 
looked in /dev/disk ?
