Dynamic reuse and reconfiguration of logical data objects in a virtual tape system

A method, comprising:

• selecting, by a processor, one of a WORM logical data object and a read-write logical data object for reuse as a new WORM logical data object, said processor maintaining data attributes bound to said selected logical data object until it is determined that said selected logical data object is available for reuse;
• assigning at least one temporary data attribute to said selected logical data object while maintaining said data attributes bound to said selected logical data object;
• and
• mounting said selected logical data object and receiving a write command to beginning of logical data object to bind at least one data attribute to said selected logical data object to replace data attributes and data associated with said selected logical data object to reuse said selected logical data object as said new WORM logical data object.

A computer program product, comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• select, by the processor, one of a WORM logical data object and a read-write logical data object for reuse as a new WORM logical data object, said processor maintaining data attributes bound to said selected logical data object until it is determined that said selected logical data object is available for reuse;
• assign, by the processor, at least one temporary data attribute to said selected logical data object while maintaining said data attributes bound to said selected logical data object;
• and
• mount, by the processor, said selected logical data object and receiving a write command to beginning of logical data object to bind at least one data attribute to said selected logical data object to replace data attributes and data associated with said selected logical data object to reuse said selected logical data object as said new WORM logical data object.
