1. Expansion fails with an error indicating that "Miscsetup::Patch_fimage/Exec[post_upgrade_script]" failed on each existing cluster node.

2. Examining the generated /opt/oracle/BDAMammoth/bdaconfig/tmp/post_upgrade_script_<ID>.out on each cluster node indicates package(s) conflicts between the OL7 packages installed on the host and a corresponding OL6 package in the bda repo, like:
