5.) mount the newly created filesystem to another directory (ex.: /tmp/versata_lib)
6.) Copy the content of the lib directory to the new filesystem
cp -R /usr/Versata/VLSComponents/Classes/RDWWPRT.ear/RDWWPRT.war/WEB-INF/lib /tmp/versata_lib
7.)smitty fs -> change file systems -> Enhanced Journaled File systems -> Change Characteristics of an Enhaced Journaled File systems : choose the newly created fs -> switch Permissions to read-only
8.) mount up /usr/Versata/VLSComponents/Classes/RDWWPRT.ear/RDWWPRT.war/WEB-INF/lib
It looks to me like this is putting the lib directory on a separate partition, and from the looks of step 8, it is probably for security reasons, so that the lib folder is never modified.
5. Creating a new partition, mount it to a temporary location
6. Copy the contents of the existing lib folder to the new partition, you'd probably want to add the (p)reserve flag to retain the existing file time stamps.
7. Change the filesystem type to read-only on the new partition. This prevents anyone from modifying the files.
8. mount the new partition over the existing lib directory for this web application. The old lib directory will still continue to consume disk space if the contents are not removed prior to mounting. (but that may be ok).
