Abstract: A storage subsystem of a computer system has at least one physical storage medium (P). Logical resources (L, R5, D, LR, FC, FW) are generated from a database containing logical resource definitions and user object definitions. The logical resources are arranged as sets of object definitions, and the selection is performed in dependence upon the physical storage media (P). User objects (110, 120, 130, 140, 150, 162, 164, 166, 170, 182, 184, 186) are generated from the database in dependence upon the generated logical resources(L, R5, D, LR, FC, FW) . In this way the generated user objects (110, 120, 130, 140, 150, 162, 164, 166, 170, 182, 184, 186) enable the computer system to utilise the physical storage media (P) via the generated logical resources (L, R5, D, LR, FC, FW). This provides a storage subsystem which is feature rich, which has far simpler source code, and which is relatively straightforward for a user.

Abstract: A software program and an object definitions database are provided for a storage subsystem of a computer system. The subsystem has at least one physical storage medium (P), The program is arranged to generate logical resources (L, R 5 , D, LR, FC, FW) from a database containing logical resource definitions and user object definitions. The logical resources are arranged as sets of object definitions, and the selection is performed in dependence upon the at least one physical storage medium (P); User objects ( 110, 120, 130, 140, 150, 162, 164, 166, 170, 182, 184, 186 ) are generated from the database in dependence upon the generated logical resources(L, R 5 , D, LR, FC, FW). In this way the generated user objects ( 110, 120, 130, 140, 150, 162, 164, 166, 170, 182, 184, 186 ) enable the computer system to utilize the physical storage media (P) via the generated logical resources (L, R 5 , D, LR, FC, FW). This provides a storage subsystem which is feature rich, which has far simpler source code, and which is relatively straightforward for a user.
