Managing Host Groups

A host group is a logical entity of two or more hosts that share access to specific virtual disks on the storage array. You create host groups with MDSM.

All hosts in a host group must have the same host type (operating system). In addition, all hosts in the host group must have special software, such as clustering software, to manage virtual disk sharing and accessibility.

If a host is part of a cluster, every host in the cluster must be connected to the storage array, and every host in the cluster must be added to the host group.

Creating a Host Group

To create host groups:

1In the AMW, select the Mappings tab.

2In the Topology pane, select the storage array or the Default Group.

3Perform one of the following actions:

•Select Mappings→ Define→ Host Group.

•Right-click the storage array or the Default Group, and select Define→ Host Group from the pop-up menu.

4Type the name of the new host group in Enter new host group name.

5Select the appropriate hosts in the Select hosts to add area.

6Click Add.

NOTE: To remove hosts, select the hosts in the Hosts in group area, and click Remove.

7Click OK.

The host group is added to the storage array.

Adding a Host to a Host Group

You can add a host to an existing host group or a new host group using the Define Host Wizard. For more information, see "Defining a Host" on page 97.
