Providing access to virtual sequential access volume

A computer program product for generating an index for a table in a database, the computer program product comprising:

• one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
• in response to instructions to determine a physical tape volume is not designated, selecting a primary physical tape volume;
• instructions to receive an access request, the access request comprising the name of a first data unit;
• in response to instructions to detect a control table associated with the selected physical tape volume, deleting all records of the control table;
• instructions to generate a segmented virtual tape file associated with the first data unit;
• instructions to write the first data unit to a specific virtual sequential access volume of the plurality of virtual sequential access volumes;
• and
• instructions to store a first file including the first data unit in the random access media, the first file being separate from a second file including a second data unit stored in the random access media in response to an operation for writing the second data unit to the specific virtual sequential access volume.

A computer system for generating an index for a table in a database, the computer system comprising:
