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 MD
Storage Manager.
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.
Use the following procedures to create a host group, to add or remove hosts
from a host group, or to delete a host group.
Creating a Host Group
1 Click the Configure tab and then click Create Host Group.
2 Type a name for the new host group in the Enter new host group name
text box.
3 In the Select hosts to add list, click the name of a host you want to add to
the host group, then click Add.
The host moves to the Hosts in group list.
4 Repeat step 3 until all the hosts you want to add to the host group are
moved into the Hosts in group list.
5 Click OK.
