Error code: F1237. SASO_FAULT

[David Duwe]

I have received the following error code on one of our B200-M3 blades.  There were no changes made to UCS about which I am aware.  The LED on the front panel is green.  I did not receive a "call home" notification.  The error occurred several days ago.  There are no known functionality issues.  Google and Cisco Support searches were fruitless.

Description:  Health LED of server #/# shows error. Reason: SASO_FAULT:Sensor Failure Asserted;

Type: equipment

Cause: health-led-amber

Code: F1237

Severity:  Major

Does anyone have any insight as to the cause and remediation of this error?

Thank you. .. . . . ... .. . . . . . .        .. .. ..

We need to check several things here:

What is the firmware version for UCSM, CIMC, bios and RAID controller for this server?

Do you see any event on SEL for sensor SASO_FAULT?

What is the HDD status for Disk 1 on UCSM?

[David Duwe]

Thank you for the response.

UCSM firmware version:  2.1(2a)

CIMC:  2.1(2a)

BIOS:  S5500.2.1.1b.0.020620132148

RAID controller (LSI):  Boot loader version:  06.34.00.00.   Running version: 01.32.09.00

Actual blade module (mistake made in original post):   B200-M2

HDD status, Disk 1 (UCSM, Equipment tab> Inventory tab> Storage tab> Disks):  States, Operability:  Operable

Additional comments:

• The "OS graceful shutdown" may have been related to a loss in SAN availability we experienced on 12/2/2013.  The SEL events are essentially identical to earlier OS restarts.  Identical events in the 12/2 restart are logged for SAS0 and SAS1.
  

• The SAS0, Predictive Failure deasserted event leads me to believe that there is nothing wrong with the disk.  This may be a "false positive."
  

• What does this additional information lead you to believe?
  

Thanks again .... . ....  . . ... . ... . . . . ..

Hi,

There is a chance that the hard disk is getting predictive failures.

You can verify this by opening KVM, reboot server, press ESC at Cisco splash screen, then during POST press CTRL+C to access LSI Config Utility, go to RAID properties and check if any of the HDDs have 'Yes' under 'Pred Fail'.

If this is set to Yes, the hard disk needs replacement.

[David Duwe]

I plan to follow your advice and check the LSI utility to see if there is a disk failure being detected.  I will schedule a server downtime for this as soon as possible and report the results here.

Thanks again for the response.  .... . . . . .. ..   .. .. .. . .

I had encountered the same alert. Reset of CIMC fixed the alert.
