Use the system control panel or HMC to retrieve the associated information to see the specific error information. &nbsp;You can follow the problem analysis process to gather this information (I picked a Power8 system - usually best to pick documentation specific to your model, but for an OS startup issue like this that isn't as important):<br />

Post back after you have identified the specific error message if you need help resolving it.<br />
<br />
Also helpful to understand if anything unusual happened before the IPL: PTFs installed, system ended abnormally, hardware maintenance, etc.

I eventually opened up a call ticket with IBM. I had to reinstall my OS... after I did that, I re-installed the latest PTFs and everything was back to normal. All the system values, libraries, user information was all as it was before the &quot;corruption&quot;. The OS re-install only updated base OS files - not the user data I had on the system (which was minimal anyway)

Glad you were able to get it resolved. &nbsp;<br />

This one can be as simple as IPLing to DST and doing a little cleanup or some other service action, IPLing off the alternate micrcode, or drastic as a reinstall or recovery. &nbsp;Really just depends on the underlying message behind the SRC.
