orachk report does not contain information about other server of the RAC
The problem appears on multiple system since a release of AHF a few months ago, on RAC systems. The nightly run send a html report but it contains information for one node only (only information for the first node on which orachk did run), the report is aware of the second node but nothing displayed for it.
Another issue, which was quite systematic, is that after the upgrade to the new version each node of the rac was sending its own orachk report, this got solved after a few day but now like I said the report does not include the second node information
