Abstract:
1. A method for switching visibility between virtual data storage entities in a data storage environment using a processor device, comprising: selecting a range of a plurality of available entities for switching visibility, the plurality of available entities including a data storage entity; queuing a switching visibility request for the range of the plurality of available entities including the data storage entity on a first storage system so as not to be visible to the first storage system; replicating data from the data storage entity from the first storage system to the second storage system using a common serial number, while the switching visibility request is queueing; hiding the data storage entity from the first storage system by concealing the common serial number; ejecting the data storage entity from the first storage system; after completion of the replicating, setting visibility of the replicated data storage entity to the second storage system to visible; introducing the replicated data storage entity to the second storage system; and upon the switching visibility request reaching a head of the queue,
