Consistency for replicating data storage subsystem configurations in accordance with a “golden” configuration file. A data storage subsystem comprises a blade system configured to support a plurality of blades and a storage system, each arranged in a predetermined slot of the blade system, and at least one zoneable switch whose zoning is disabled at power on. A management module operates the blade system to power on all slots. The storage system, in accordance with a “golden” configuration file, transfers port enablement sequencing to the switch, and the switch enables and zones ports in sequence to allow the server blades to see the storage system in accordance with the port enablement sequence. The storage system is configured with the “golden” configuration file to log on the server blades in accordance with the port enablement sequence to logically configure the server blades in accordance with the “golden” configuration file.
