If you have to fall back to an RVU prior to G06.00 and the spooler control file format is
from a spooler version prior to T9101ADM, you must restore copies of both the control
file and the collection files that were in use.
If your previous product version of spooler was T9101D41 SPR ADM or later, you do
not need to restore copies of both the control file and the collector data files if you back
out of your G06.24 RVU. All versions of T9101D41, starting with T9101D41 SPR ADM,
contain Version 5 of the spooler control file and are compatible with T9101D46 and
D48 product versions of spooler. However, it is always recommended that you back up
the spooler control file and collector data files before migrating or applying spooler
SPRs.
See Support Notes S97057 (T9101D41 Spooler Collector Data Files Have Changed
Format) and S99086 (NSK Spooler — Migration and Draining Instructions) for more
information.
Open System Services (OSS)
Back up the OSS configuration database files before falling back. See the Open
System Services Management and Operations Guide for more information.
OSM and TSM
See the OSM Migration Guide for complete information. If you installed OSM after
installing the G06.24 RVU, and you want to fall back to a newer SPR of TSM, see TSM
Server and Client Compatibility SPRs on page 3-10 and the Interactive Upgrade
Guide.
SMF
The record format of the system configuration database sometimes changes between
RVUs and is automatically converted to the new format the first time the system is
loaded. To ensure system configuration integrity, always:
1. Save the system configuration after SMF configuration changes are made.
2. Reload the system from the current system configuration file or the latest version
with SMF changes.
See the Storage Management Foundation User’s Guide for more information.
Caution. Create a saved version of the configuration before loading a new RVU. If this step is
omitted, you cannot fall back to a previous RVU.
