Creating a Host Group

To allow hosts to use volumes, you must add hosts to host groups. Then, establish mappings between volume groups and host groups. By doing so, hosts in host groups can use volumes in volume groups. A host group can contain one or more hosts.

Procedure

  1. Choose Services > Block Service > Host Group.
  2. Click Create.

    The Create Host Group page is displayed.

  3. Set the name of the host group.

    • The name must be unique.
    • The name contains 1 to 31 characters.
    • The name can contain only letters, digits, underscores (_), hyphens (-), periods (.), and colons (:), and must start with a letter, digit, or underscore (_).

  4. Select the hosts you want to add to the host group.

    In the Available Hosts area, select one or more hosts and they are added to the Selected Hosts area on the right automatically.

    If hosts to be added into the host group belong to different clusters, data access conflict may occur, resulting in data loss. Before performing this operation, you are advised to install cluster software to manage such hosts.

  5. Click OK.
  6. Confirm your operation as prompted.
