A host cluster is a group of logical host objects that can be managed together. For example, you can create a volume mapping that is shared by every host in the host cluster. The systems use internal protocols to manage access to the volumes and ensure consistency of the data. Host objects that represent hosts can be grouped in a host cluster and share access to volumes. New volumes can also be mapped to a host cluster, which simultaneously maps that volume to all hosts that are defined in the host cluster.
You can use several tools to manage host clusters, including the management GUI, and the command-line interface (CLI). To work with host clusters in the management GUI, select .
