Exadata Database Machine X2-2 Hardware - Version All Versions and later
Information in this document applies to any platform.
Cell Machine X4270 M2 becomes non-responsive, eventually resulting in a node panic and we also loose access to iLOM.
Resulting in me having to disconnect/reconnect power cables to restore stability.
Two Symptoms experienced as a result of this hardware problem.
1). ILOM becomes non-responsive resulting in an engineer having to restore stability by disconnect/connect power cables again.
2). CPU Node panics due to detected stalls on a particular CPU. These may or may not occur with any regularity.
