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.
