Before you can map a host group to one or more volumes, the host group must have at least one host associated to at least one initiator.
When you explicitly map a host group to a volume, the management software removes the host group and specified volume from the default storage domain and creates a separate storage domain.
To map a host group to one or more volumes:
The Array Summary page is displayed.
The Volume Summary page for that array is displayed.
The Host Group Summary page is displayed.
The Host Group Details page is displayed.
The Map Host Group page is displayed.
The management software maps the volume to the host group and displays the Host Group Details page with the updated information.
