Array controller P420i [Embedded] has reported that it previously locked up with code 21234451.

My server is down and need to cold boot.

After server boot up and checked the system logs, an event message is shown:

"Array controller P420i [Embedded] has reported that it previously locked up with code 21234451."

And another message is:

System Information Agent: Health: Post Errors were detected.  One or more Power-On-Self-Test errors were detected during server startup. Details of the POST error messages can be found in  Integrated Management Log.
[SNMP TRAP: 6027 in CPQHLTH.MIB]

Any idea on this issue?

My OS is: Windows Server 2008 R2 Standard 64Bits SP1
