LUN operations description: 
Attach 
Attach a logical unit number to a user data volume. 
Detach 
Detach a logical unit number from a user data volume.
 
The matching rules of access control are from top to down by sequence. For 
example: there are 2 rules for the same UDV, one is “*”, LUN 0; the other is 
“iqn.host1”, LUN 1. The other host “iqn.host2” can login because it matches the 
rule 1. 
 
The access will be denied when there is no matching rule.
