Mapping of logical volumes to host clusters

摘要

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.

1. A method for storing data in a distributed network comprising a plurality of host computers in communication with a data storage system comprising a plurality of logical volumes including a first subset of the logical volumes, the plurality of host computers including a first subset of host computers including at least a first host computer and a second subset of host computers including the first host computer and a second host computer that is not included in the first subset of host computers such that the first host computer is included in both the first subset of host computers and the second subset of host computers, said method comprising:
receiving a single first mapping instruction that specifies a first volume group and one of the first subset of host computers and the second subset of host computers; and in response to receiving the single first mapping instruction, mapping, by a processor, each host computer in the one of the first subset of host computers and the second subset of host computers to each logical volume in the first subset of the logical volumes.
