TapeGen introduction

TapeGen is a service tool from IBM that enables you to create a stacked tape containing SMIT installable fixes. You create a stack file that lists all the images you want stacked onto a tape and TapeGen does the rest.


The PTF images must be installable through SMIT. This means the fixes must be in installp format.

The tape device must have the block size set to 512.

The stack file must contain a list of PTF images that are to be written to tape.
