A system for accessing logical devices provisioned with a capacity from physical devices managed by a control unit, comprising:

• a processor;
• and
• a computer readable storage medium having computer readable program code embodied therein that when executed by the processor performs operations, the operations comprising:
• establishing with the control unit an association of logical devices and alias addresses assigned to the logical devices, wherein the alias addresses are associated with an alias management group;
• generating alias address pool information indicating each of the logical devices and their assigned alias addresses indicated in the association;
• and
• using from the alias address pool information any one of the alias addresses in the alias address pool information to access any of the logical devices associated with a same alias management group as the alias address.
