Techniques are presented for clustering data storage including (a) announcing, using zeroconf, to a local network, a service provided by a DSA and an unreserved state of the DSA, the service being of a clusterable data storage type, (b) receiving a cluster command from a configuration management device connected to the local network, the cluster command directing the DSA to join a storage cluster to present combined storage of the DSA and at least one other DSA, and (c) in response to receiving the cluster command: (1) announcing to the local network via L2 multicasting that the DSA has entered a reserved state using zeroconf, (2) afterwards, performing configuration operations including updating system parameters, resulting in the DSA becoming part of the storage cluster, and (3) while in the reserved state, receiving another cluster command directing the DSA to join another storage cluster, and, in response, refusing the other cluster command.
