Abstract
A method for data storage includes defining a host cluster within a group of host computers, which access a storage system that includes multiple logical volumes. The host cluster includes two or more of the host computers. A single mapping instruction, which specifies the host cluster and a set of one or more of the logical volumes, is accepted. Responsively to the single mapping instruction, each of the host computers in the host cluster is mapped to access the logical volumes in the set. In another disclosed method, a single control instruction, which specifies the host cluster and a configuration operation to be applied to the host computers in the host cluster, is accepted. Responsively to the single control instruction, the configuration operation is applied to each of the host computers in the host cluster.
