z/VSE Virtual Tape Support

This page describes important aspects of using and working with the Virtual Tape Support available with z/VSE. Please refer also to VSE/ESA Release Guide V2.6 chapter 7.

In general, the z/VSE Virtual Tape Support included in z/VSE is intended to be transparent to applications and to provide the customer with the ability to read from or write to a virtual tape in the same way as if it were a physical tape.

For technical and performance reasons, the full range of the capabilities of a physical tape has not been implemented.
