OPS Failing fault.ops.chassis.voltage.fail on FRU /SYS/MB at Component /SYS/MB (18070361)
If you have upgraded the system firmware to version 9.1.1, you might see error messages like the following in the SP log, especially after you power cycle the server.
2014-01-08/23:20:03 ereport.chassis.voltage-unc-ghi@/SYS/MB
detector = /SYS/MB/V_+12V_3V3_STBY_OBPS
hidden = true
reading = 11.9141
threshold = 11.844
Additionally, if you use fmdump -eV, you might see an ereport titled ereport.chassis.voltage-unc-ghi@SYS/MB for detector /SYS/MB/V_+12V_3V3_STBY_OBPS.
 | Caution - Do not power cycle the server if you have removed the power supply in PS0 or if you have removed the power cord from PS0. The server will not boot under these conditions. |
Workaround: You can safely ignore these messages and ereports. However, the messages are retained in the SP log.
Fix: Upgrade to system firmware version 9.1.2, or later, as soon as it is available on MOS. You can also reinstall system firmware version 9.1.0.f.
