Yeah…just wanted to document this here for me. Hopefully you can make some use of it as well.
Before opening up a case with HP Support for HP Proliant servers (at least Gen8 and newer) make sure you grab a AHS support log. They will in 99.9% of cases ask for this log before doing anything. Also, if it is a blade server make sure you grab a “show all” from the OA.
The easiest way to get this is to download the log through iLO (at least possible with firmware 2.03 and newer). Go to Information -> Active Health System Log. Pick out the time range you want the log for and fill out the contact information and press Download!
Here is a guide from HP for alternative ways to get the log.
