The Platform Vendor Independent Check (PVI checker) is the same utility that is executed by the AEP installer (aepinstall.sh). The PVI checker (pvicheck.sh) can be run by customers outside of installation. That is, a customer can check the prerequisites or preinstall these packages before installing Experience Portal.
The PVI checker is located under Support/PrereqCheckerInstaller of the Experience Portal media.
 | Note: |
Experience Portal does not bundle any packages that are obtained from Red Hat. Experience Portal provides a PVI checker that installs all Red Hat Enterprise Linux packages that are needed to install Experience Portal, provided that customers configure a valid yum repository on the system that contains all required Experience Portal prerequisites. Customers can either run the Experience Portal PVI checker standalone outside of installation or alternatively run the PVI checker within the Experience Portal installer. All OS packages required by Experience Portal are standard Red Hat Enterprise Linux packages. Since Avaya Enterprise Linux for Experience Portal 8.x already contains all the required prerequisites, this note primarily applies to software-only customers.
The PVI checker can be executed by running the bash pvichecker.sh script. This checks all the pre-requisites required such as non-root account, hostname resolvable, required Red Hat RPM packages installed, and then lists the ones that passed or failed.
If the PVI checker is invoked with the -install parameter, that is running pvicheck.sh -install , it installs any missing RPMs, provided a yum repository is configured. It also performs other correction tasks like adding hostname to /etc/hosts and disabling firewall.
The PVI checker can also be invoked with the -headless parameter which suppresses the need for user input.
