An administrator finishes an installation of a new NetApp ASA system at the customer site...

To restrict access to a newly created LUN to specific hosts, the administrator should configure theigroup(initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs. This ensures that only authorized hosts can access the storage, enhancing security and access control.
