Purpose

The purpose of this document is to assist in the troubleshooting of fan related alerts for the 7xx0 Unified Storage Appliances.

Details

Symptom: Appliance has an amber LED lit for Fan Module / Fan Power Board and (or) an alert was received from the appliance indication that there is a FAN related failure.

Resolution:

1. Confirm whether you have one of the following faults via:

BUI (Browser User Interface) -> Click MAINTENANCE, PROBLEMS
or
CLI (Command Line Interface) -> 'maintenance problems show'

SENSOR-8000-26: External sensors indicate that the fan 'xxxxxxxx/FB X FM X' is no longer operating correctly.
SENSOR-8000-26: External sensors indicate that the fan 'xxxxxxxx/FT X' is no longer operating correctly.

2. Check the fan to see if it has lost power or there is a physical obstruction.

If fan has power and there is not a physical obstruction, but the fault remains -> Step 5.
If the fan is currently operating as expected proceed to Step 3.

3. Verify SP version via

BUI -> Click the Sun/Oracle Logo in the upper left corner of the BUI, 'Service Processor' version is located at the bottom.
or
CLI -> 'configuration version show', Service Processor at the bottom

If SP <= 2.0.2.5, these versions contain the SP memory leak bug. It is highly possible that you are hitting bug#6869041. SP version 2.0.2.16 fixes the SP memory leak issue. Once SP FW has been updated then verify if the FAN fault persists. Please engage an Oracle Support Engineer (see end of document) to assist with upgrading the SP firmware level
If SP >= 2.0.2.16, Then Proceed to Step 5.

4. Is this a re-occurring failure on this particular FAN location?

Yes? Engage Engineer to investigate replacement (see end of document)
No? Monitor appliance to see if the Fan errors persist. If the Fan errors persist, proceed to Step 5.

5. Engage Support Engineer (see below) to investigate as a systemic issue.

Note: For Sun ZFS Storage 7x20 systems, using the 3.x ILOM version, please be aware of ... CR 7035044 : Exadata x2-2:: S0/G0 ACPI state changes to working for no apparent reason.
( Current rev : 3.0.9.25 ) This bug is also known to lead to 'false' reporting of PSU/FAN failures.

Engaging a Support Engineer

Please update your SR if the proposed solution did not fix the issue, a support engineer will then be assigned to assist.

Without further updates we will close this SR in 14 days.
