This resource shows LUN masking information. 

Host Group The logical grouping of initiators (hosts) and LUNs. The LUNs in the group are visible to all the initiators in the group. Sometimes this group may contain storage array ports as well. Different array vendors use different names such as Storage Group, iGroup, etc.
Host Alias The alias given to the initiator (host) or initiator port. Normally the hostname of the initiator.
Initiator LUN ID The number used by initiators in a Host Group to identify a LUN. The LUN ID is unique within the Host Group.
Initiator Endpoint The WWPN (World Wide Port Name) or IQN (iSCSI Qualified Name) of the initiator port.
Target Endpoint The WWPN or IQN of the port on the target (storage array) through which the LUN is accessible to the hosts.
