Backing Out the DSM/SCM Revision
This section describes:
Products that might have fallback implications. Before falling back or backing out
the revision, review the appropriate product softdocs.
Using DSM/SCM to back out the revision.
Products That Might Have Fallback
Implications
Review the H06.09 Release Version Update Compendium and product softdocs to
make sure that your installed products do not have migration implications.
Open System Services (OSS)
Back up the OSS configuration database files before falling back. For more
information, see the Open System Services Management and Operations Guide.
OSS Large Files support, introduced in the H06.07 RVU, has created fallback
issues. See OSS Large Files on page 2-4.
Storage Management Foundation (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.
For more information, see the Storage Management Foundation Users Guide and the
required SMF softdocs.
Safeguard
A new password encryption algorithm was introduced in H06.06. This change has
fallback implications when falling back to a pre-H06.06 RVU, because new passwords
will not be valid on the RVU to which you are falling back. The new passwords must be
expired and users must revert to their previous passwords. For a detailed fallback
procedure, see New Safeguard Attribute Defaults on page 2-17.
Caution. Create a saved version of the configuration before loading a new RVU or revision. If
this step is omitted, you cannot fall back to a previous RVU or revision.
