There is a specific package for each RedHat release. The "/usr/lib/systemd" directory is typical for a RedHat 7.x environment. In this case, the customer attempted to install a package compiled for RedHat 7 ... on a RedHat 6 environment.

Check etc/redhat-release to confirm that the RedHat release is indeed the release expected by the PowerPath package.

The message was generated by the installation of a package for RedHat 7.x in a RedHat 6.x environment. When the correct package was used, the installation completed successfully.
