3.7.0 HP StorageWorks HP Scalable NAS File Serving Software upgrade guide HP Scalable NAS for Linux (AG513-96005, October 2009)

Back up system, database, and MxDB-Oracle-HiAv files
Before starting the upgrade, make a complete system backup and have a recent full
database backup and archive logs available. As this upgrade requires a complete
replacement of the OS and server hardware, be sure to capture local Oracle files
such as /etc/oratab that will not be preserved so you can reconfigure the new
system correctly.
Also save the following MxDB-Oracle-HiAv information:
• Record the configuration of the active Virtual Oracle Servers (for example, the
name, Virtual IP address, Port ID, and so on) from your 32-bit cluster, as you will
need that information to recreate the Virtual Oracle servers on the 64-bit cluster.
This information is available in the Oracle tnsnames file or can be obtained via
the mxdb console.
• Preserve any custom MxDB-Oracle-HiAv files. For example, MxDB-Oracle-HiAv
supports the optional configuration file mxdbha_<DBNAME>.conf, where <DB-
NAME> is the name of the service monitor associated with the Virtual Oracle
Service. If used, the file is located in $ORACLE_HOME/dbs.
• Save any custom probe scripts in ${ORACLE_BASE}/admin/<DBNAME>/
scripts and custom startup scripts in /opt/hpcfs/mxdb_oracle_ha/.
You should have access to the old $ORACLE_HOME from an upgraded node;
however, you will lose anything local, such as oraIventory files (if local), the
Oracle UNIX account directory, /etc/oratab, and so forth, unless you take steps
to preserve what you need.
Uninstall MxODM
The PolyServe MxODM product has been discontinued in the 3.7.0 release. Recent
Linux changes have made this product unnecessary. This product should be uninstalled
from the cluster before upgrading to HP Scalable NAS version 3.7.0. You should be
aware of the following before uninstalling MxODM:
• Be sure that there are no Oracle Instances running on any nodes in the cluster.
• The package must be uninstalled from the node where you installed it.
• Ensure that the PSFS filesystems used by Oracle are mounted.
To uninstall MxODM, run the following command as user root:
# rpm -e odm-3.5.3
