Removed Fan or Fan Module

What Caused the Problem?

A fan or fan module has been removed from the storage array. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution: Possible loss of data accessibility. Do not remove a component when either (1) the Service action (removal) allowed (SAA) field in the Details area of this recovery procedure is NO (), or (2) the SAA LED on the affected component is OFF (note that some products do not have SAA LEDs). Removing a component while its SAA LED is OFF may result in temporary loss of access to your data. Refer to the following Important Notes for more detail.

Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

If this problem appeared because you removed the fan module when told to do so in the Recovery Steps of a different problem - such as a Failed Fan or Fan Module problem - then disregard this problem and do not continue with the Recovery Steps. Instead, complete the Recovery Steps for the original problem and this problem should be resolved as well.
When a fan is failed, redundancy is lost for the storage array's cooling systems. The remaining fan or fan module will continue to provide cooling; however, failure of this fan unit will result in the storage array exceeding temperature limits. Therefore, make sure you correct this problem as soon as possible.
If necessary, refer to the applicable hardware manual for detailed replacement procedures.
Service Action Allowed Important Information:
- The Service action (removal) allowed field in the Details area indicates whether or not you can safely remove the component. If the SAA field is NO (), then the affected component must remain in place until you service another component first.
- The Service action LED on Component field in the Details area indicates whether or not a physical SAA LED is present on the hardware component. This field does NOT indicate whether the LED is ON or OFF (that indication is provided by the Service action (removal) allowed field).
- If a component does not have an SAA LED, then it is OK to remove the component when its fault LED is lit and the Service action (removal) allowed field = YES () in the Details area.
- The Service action (removal) allowed field shown in the Details area and the physical SAA LED on the hardware component (if supported) MUST match before you remove the affected component. In rare cases (such as multiple problems), the status of the LED and the SAA field may not match. If there is a mismatch, then you should NOT remove the component until these indications match.

Recovery Steps

Refer to the 'Component requiring service' field in the Details area.

If...

Then...

The component requiring service is the fan module

Go to step 2.

The component requiring service is the power-fan module that contains the fan

Complete the first task below, then click the Recheck button before proceeding to the next task:

a	Replace any components that were recently removed.
b	Replace any components that are being reported as failed in the Summary area.
c	Complete the Recovery Steps for any other problem reported in the Summary area.
d	If this problem is still reported in the Summary area after completing the three steps above, contact your technical support representative to assist you with correcting this problem. Do not continue with the remaining Recovery Steps.

If the fan module does not appear to be missing from the storage array, re-seat the fan module in the enclosure by removing it and reinserting it.

If you are replacing the fan module with a new unit, then check the model of the fan module you removed and ensure that the new fan module is the same model.

If you do not have a module that is the same model, contact your technical support representative.

Insert the new or original module securely into place.

Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.
