1. A system comprising: a management client in a network storage environment, the management client in communication with a storage system of the network storage environment, the management client configured to: access and manage a plurality of host-to-volume mappings, each one of the host-to-volume mappings specifying at least one host initiator accessing at least a subset of logical volumes of the storage system, the host-to-volume mappings being stored at the storage system, wherein only one mapping of the plurality of host-to-volume mappings is in an active state at a given time; permit a host of the at least one host initiator to access only those volumes mapped to the host by the one mapping that is in the active state; and effecting a repartition or repurpose of the at least one host initiator by deactivating a first host-to-volume mapping and activating a second host-to-volume mapping to modify access of the at least one host initiator to the logical volumes of the storage system.
