When you create a host group, it is automatically included in the default storage domain.
To create a new host group:
The Array Summary page is displayed.
The Volume Summary page for that array is displayed.
The Host Group Summary page is displayed.
The New Host Group Details page is displayed.
Note: A host can be in at most one host group at a time. If a host is already included in one host group, adding that host to another host group will move the host from one group to the other.
The Host Group Summary page is displayed listing the new host group.
