A Blank Screen Is Displayed When the RH2285 V2 Is Powered On

Publication Date:  2015-06-19 Views:  134 Downloads:  0
Issue Description
Hardware configuration:
RH2285 V2

Software configuration:
Basic input/output system (BIOS) V029 and iMana 3.59

Symptom:

A blank screen sometimes is displayed when the RH2285 V2 is powered on, and no signal is output. After the server is restarted several times, the blank screen persists.
Handling Process
1.  Collect information over the serial port.

Log in to the iMana over Telnet and run ipmcset -d download -v 0 to collect information over the serial port, as shown in Figure 1.

2.  Analyze the information.

Information printing stops at "Continue with system BIOS POST...", indicating that the BIOS power on self-test (POST) fails, as shown in Figure 2.

3.  Restart the server.

Restart the server several times. It is found that information printing always stops at "Continue with system BIOS POST...".
Root Cause
The Fvheader of OemFv is lost, so the server cannot start. The Fvheader may be lost if the server is unexpectedly powered off when it starts for the first time.

This issue occurs in the BIOS of V036 or earlier.

Solution
Upgrade the BIOS to a version later than V036.

Suggestions
Collect the serial port information of the iMana and then upgrade the BIOS to the latest version.
