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 using the 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.
Creating A Host Group
To create a host group:
1. In the AMW, select the Host Mappings tab.
2. In the object tree, select the storage array or the Default Group.
