Partitioning of a multiple logic-unit-number SCSI target

A computer program product for assigning logic storage entities of a storage device to multiple partitions of a computer system, the computer program product comprising:

• a non-transitory computer usable medium having computer usable program code embodied therewith, the computer usable program code comprising:
• instructions to associate each logic storage entity to at least one of the partitions that is allowed to access the logic storage entity;
• instructions to configure a partition supervisor to control accesses of the partitions to the logic storage entities, so that the partitions can share resources when accessing the logic storage entities;
• and
• instructions to provide an interceptor in the partition supervisor, the interceptor modifying a request, sent by one of the partitions, that attempts to access any of the logic storage entities that the one partition is not allowed to access, and removing response data sent from one of the logic storage entities to any of the partitions that is not allowed to access the one logic storage entity.

A computer system comprising:

• a processor;
• a memory operatively coupled with the processor;
• a storage device operatively coupled with the processor and the memory;
• and
