Falling Back to a G06.xx Release Version Update
•
There is an increased risk of loss of files if double failure of the disk process
occurs. If there is a double failure of the disk process serving a fast-create
fileset, recently created files might be permanently lost.
•
After failure of both primary and backup OSS name server processes, when
the OSS Monitor remounts a fast-create fileset, the remount is rejected by the
OSS name server. The OSS Monitor automatically runs diagnostics, attempts
to repair the fileset, and then retries the remount.
HP recommends that you have a fast-create fileset named TEMP mounted on the
OSS /tmp directory.
3. Save the file as $SYSTEM.ZXOSSMON.ZPCONFIG.
Falling Back to a G06.xx Release Version
Update
The first time a G09 or newer OSS Monitor runs on a system that has a D46 OSS
Monitor installed, a copy of the existing D46 Monitor database is created. In the copy,
the names of the files have the prefix “ZOSS” instead of the original prefix “ZPOS”; for
example, ZPOSFSET is copied to ZOSSFSET. The copied files (whose names begin
with “ZOSS”) are extended to include new fields that support OSS security auditing.
After this, the G09 or newer OSS Monitor uses the converted database and ignores the
original D46 Monitor database.
To fall back to a G06.12 or more recent RVU:
•
If no new features are used and there are no changes to configuration records, you
can safely fall back without any special preparation.
•
If there are changes to the configuration records and new features are used, you
need to consider the following:
°
If either the INODECACHE or LINKCACHE OSS name server attribute was
changed to a value greater than 250000 after installing the T8622G11 or a later
release and you fall back to a release with a product version prior to
T8622G11, the SCF START FILESET command will fail with error OSS
E00008 on any fileset managed by the affected OSS name server. To avoid
this error, use the SCF ALTER SERVER command to change the
INODECACHE or LINKCACHE attribute value to a value lower than or equal to
250000 before any filesets using that OSS name server are started.
To fall back to a G06.xx RVU (where xx is less than 12):
•
If you installed software product revision (SPR) T8622D46_AAH, simply load the
G06.xx RVU:
°
If no new features are used and there are no changes to configuration records,
you can safely fall back without any special preparation.
