Thank you for your answer.  Before you say something please be careful.  I am NOT "blind".  We have more than 100 DELL servers on different classes and use different tools to monitor system (include OPMN).

We have been doing lots of research on this issue and also discuss With DELL support at least three times but NOT get good answer.

This PERC 6/E is NOT on "battery lean cycle" and we understand what will happen on "battary lean cycle".
