Abstract
Method, system, and computer program product embodiments for concurrent copy of system configuration global metadata in a data storage system are provided. In one exemplary embodiment, a global data rank is quiesced, followed by an unquiesce of the global data rank except for a global metadata area. The global metadata area is updated in memory, and then unquiesced. A current range of the global metadata area to be copied is quiesced. The current range of the global metadata area is copied from a source area to a target area. The current range is unquiesced. The steps of quiescing an additional current range, copying the range from a source area to a target area, and unquiescing the current range continue until the entire global metadata area has been copied.
