HP XC System Software Installation Guide Version 4.0

user customizations that were not merged into the new files in this release. This example
uses the grep command to search for the affected files.
# grep -E ".rpmsave|.rpmnew" /var/log/postinstall.log
2. Use the method of your choice (the diff command, for example) to determine differences
between the customized and current versions of configuration files. As software evolves,
configuration file formats might change. Carefully compare the original configuration files
to the new files before integrating your changes.
3. Carefully copy customizations from the *.rpmsave version of the file into the new version
of the file. Certain *.bak files must also be considered for merging if they have been
previously customized.
As an example, the /opt/hptc/systemimager/etc/chkconfig.map.rpmsave file
contains the previous customized contents, and you use it to determine the customizations
you have to manually add into the new version of the file, which is /opt/hptc/
systemimager/etc/chkconfig.map.
Table 9-6 contains a list of configuration files that are specific to HP XC and standard Linux
configuration files that are likely to contain user customizations that you must merge.

If the head node was previously
configured as a NIS slave server, do not
merge the nis ports from the
iptables.proto.rpmsave file into
the iptables.proto file because the
nis_server service automatically opens
the necessary ports when it is configured
during cluster_config processing.

4. Follow the same process to open and search the log files for customizations that are specific
to Linux configuration files. Perform this step only if you know you changed standard Linux
configuration files.
Search the files for configuration files that have either an .rpmsave or an .rpmnew extension
appended to them.
# grep -E ".rpmsave|.rpmnew" /root/upgrade.log
