If something is logging in with the same initiator name and ISID as  
an existing session, and it further passes the security phase (either  
you are configured for no security or the new initiator successfully  
authenticated), then IT IS THE SAME INITIATOR.

You are supposed to follow the session reinstatement operations  
described in RFC 3720.

Doing anything else would have a number of other, severe, consequences.

We (Wasabi) have had customers end up with end-systems that all had  
the same initiator name and ISID. Since we have to do session  
reinstatement, we ended up having systems keep logging each other out.

Our solution was to add the IP address of a logging-in initiator to  
our log messages. Thus if you see 192.168.1.2 and 192.168.1.3 both  
using the same name over & over, you know what the problem is.

Take care,

Bill
