8202-E4D manual mode - who dun it?

Our end of month routine does a full system backup followed by an IPL of the system.

Yesterday the system did NOT come up because of an A6005008 error - no console available message.

Turns out the mode was switched to manual from normal.

Is there any way to track what profile might have done that?

We know that it was in normal mode on 7/31/16 and we know that it was in manual mode on 8/31/16.

In our case extremely unlikely anyone w/could have done it manually at the machine. I'm not sure anyone even knows how to release the panel from the front of the machine.

Thus the only access to the mode setting would be through Ops Console.

The only person who was in Ops Console recently confirms that he didn't do it (when applying PTFs recently). Also, he wouldn't have necessarily noticed if it was set to manual or normal mode because during PTF load/apply Ops Console is up and running so there wouldn't be an A6005008 and the system would go ahead and IPL with the DSP01 available.

Lastly there was an AC power event and we are wondering if something related to that event could have set the mode to manual.

Otherwise any ideas? Anybody have experience with this?

Thanks,

Jerry
