Removing OSS Management Information From the
DSM/SCM Databases
3. Run the FALLBACK macro immediately after you back out to a pre-D46 PVU but
before you run STARTSCM.
You need to run the macro separately for the host and target systems, but only for
whichever systems have been backed out. For example, if your target system is
still running the D46 PVU, do not run the macro on the target system.
The FALLBACK macro must be run from the ZDSMSCM subvolume by the
DSM/SCM user ID or the super ID (255,255) only.
4. Address any errors returned by the FALLBACK macro.
5. If there are no errors, when FALLBACK prompts you to continue, enter Yes.
The FALLBACK macro begins processing. Though the macro does not remove
OSS files, it removes all OSS management information from the DSM/SCM
databases. Therefore, you must always use the COPYOSS procedures to install
OSS software until you re-enable DSM/SCM to manage OSS files.
6. After the FALLBACK macro indicates it is running IPM6031, which is its final step,
you can run STARTSCM.
To later manage OSS files again, you must migrate to the DSM/SCM D46 or later PVU
and receive the software into the archive again to properly process the
DSM/SCM-enabled OSS software.
