Using DSM/SCM FALLBACK and CLEANOSS Macros
If you need to fall back from an RVU that does not have installed a D46 DSM/SCM
PVU, you must run the DSM/SCM FALLBACK macro from the ZDSMSCM subvolume.
The interactive macro must be run by the DSM/SCM owner or by super ID (255,255).
The FALLBACK macro reverts the DSM/SCM Host or Target, or both, database back to
a pre-D46 state for use by a pre-D46 product version of DSM/SCM. The FALLBACK
macro removes all DSM/SCM OSS management information. Therefore, you must
always use the COPYOSS procedures to install OSS software until you re-enable
DSM/SCM to manage OSS files.
To later manage OSS files again, you must migrate to the DSM/SCM D46 PVU and re-
receive the software into the archive to properly process the DSM/SCM-enabled OSS
software.
If a Host and Target system are running on the D46 product version of DSM/SCM and
only the Host falls back to a pre-D46 product version, run the FALLBACK macro only
on the Host system.
Notes on the FALLBACK Macro
The FALLBACK macro will not be available in the ZDSMSCM subvolume when you fall
back to an RVU prior to G06.18. Therefore, you must retrieve the FALLBACK macro
from the SUT prior to falling back or use the FUP DUP command to copy it to a
subvolume for use during fallback.
Note that you can migrate back to an earlier RVU SUT version without migrating back
to an earlier DSM/SCM version. To do this and eliminate the need to run the
FALLBACK macro, copy T6031D46 into the configuration on top of the older SUT. See
the DSM/SCM User’s Guide for more information.
Notes on the CLEANOSS Macro
If you fall back and then migrate to a G06.18 or later RVU, DSM/SCM might notify you
during the Apply that the CLEANOSS macro must be run. The current OSS
environment is being managed by a logical target other than the one trying to manage
OSS files with the current DSM/SCM Build/Apply. You must cancel the Apply, and run
the CLEANOSS macro. The EMS message gives you basic instructions:
The current OSS environment is managed by target oss-system
(according to /zzDSMSCM.Managed). To switch OSS management
from oss-system to target-system, CANCEL the Apply, run
CLEANOSS, run Verify Database, then RESTART the Apply.
If you receive the following EMS message (5305), or a similar one, it indicates that you
are running the D46 PVU of T6031 but not the most current EMS templates to
effectively display the CLEANOSS message. It is possible that you restored the
T6041D46 PVU from tape and activated it, but the correct templates were either not
properly installed or the NonStop Kernel is pointing to the wrong template files:
