Folks,

I have gone through various articles on setting up iSCSI initiator and have 
successfully managed to share an iSCSI volume following the steps. This was a 
simple test scenario. Now, I am trying to set up a specific scenario but I am 
confused on proper relationship between various terms that are used. I would 
appreciate your help in making me understand the relationship between the 
following terms:

- Volume
- LU 
- Target
- Target Group
- Target Portal Group
- Host Group
- View

As I understand:
1. There is a one-to-one relationship between a volume and its LU.
2. A target group consists of targets and a host group consists of hosts.
2. A view consists of one host group, one target group, and one or more LUs.

What I don't understand:
1. At first, I thought there is a one-to-one relationship between an LU and a 
target. However, this doesn't seem to be the case. Why would you need more than 
one target in a target group? 
2. Where does the target portal group fit in?

In my scenario, I would like to share volumes v1 and v2 with hosts h1 and h2. I 
would also like to limit the network to go through ip addresses p1 and p2 only. 
Can someone please give me just the broad steps;''

Thank you in advance for your help.

Regards,
Peter
