Impact

One of the two types of failures listed below may occur on the Service Processor (SVP):

1) Both a false FAN failure and a Windows failure may occur in the SVP at the same time. Approximately 15 minutes later, the SVP will re-boot itself automatically. During the SVP re-boot, the administrator will be unable to use the Storage Navigator for about 3 minutes. The following SIMS will be generated:

FAN failure: SIMRC=bfe401 (SIM level: moderate)
Windows failure (COM port open failure): SIMRC=75ff00 (SIM level: moderate)

2) A false FAN failure is detected in the SVP, a SIMRC=bfe401 (SIM level: moderate) and possibly an SSB log (333e) and is recorded either once or every 10 seconds. To determine if a real SVP FAN failure has occurred, you must complete any bfe401 SIMs, then reboot the SVP and see if another bfe401 SIM occurs after 10 minutes. If so then it is real and the SVP will need to be replaced.


Root Cause

False detection of SVP FAN Failure due to an improper driver (firmware) control for the RAS. Conditions of occurrence:

SVP WDM driver: V1.0

Note: The procedure to check the driver revision is described in the FCB posted at http://se9990.eng/HECN/510-HW/f515h002.pdf


Workaround

To determine if a real Service Processor (SVP) FAN failure has occurred, you must complete any bfe401 SIMs, then reboot the SVP and see if another bfe401 SIM occurs after approximately 10 minutes. If so then it is real and the SVP will need to be replaced.

Examine the failure type, and take the following action:

Condition A:

  1. Complete any SIMs SIMRC=bfe401, and 75ff00.
  2. Reboot the SVP, then wait 10 minutes, and check if any new SIMRC=bfe401 have occurred.
  3. If yes, then replace the SVP.
  4. If no additional SIMRC=bfe401 = No action.

Condition B:

  1. If the Storage Navigator does not function, please reboot the SVP.
  2. After re-booting the SVP, please complete SIMRC=bfe401.
  3. Wait 10 minutes, and check if any new SIMRC=bfe401 have occurred.
  4. If yes, then please replace the SVP.
  5. If no additional SIMRC=bfe401 = No action.

Resolution

Install fixed driver revision - SVP WDM driver Rev. V1.3

Refer to the instructions in ECN DKC515I-H002 and FCB DKC515I-H002
