- The file "/usr/lpp/bosinst/bosmain" is the program that manages the base
- operating system installation process. It MUST be there in order for
- installation to work.
- The question that comes to mind is: why isn't that file on the system?
- You say the backup is that of a freshly built system, yet something on
- the system has been modified if the bos installation executables are
- not there.
- It might help if you modify the "mkinsttape" command and remove the
- redirects to /dev/null. The "mksysb" command calls the "mkinsttape"
- command to create the image on the tape that contains the installation
- utilities. If you remove the redirects to /dev/null, then you will be
- able to see any error messages that have been suppressed. In all
- probability you will see something about "file not found" as the
- installation utilities files are being backed up into the tape image.
- If you can fix this situation, then the chance of the tape working will
- be much better.
