Removed Fan or Fan Canister
What Caused the Problem?
A fan or fan canister has been removed from the storage subsystem. 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 canister
when told to do so in the Recovery Steps of a different problem -
such as a Failed Fan or Fan Canister 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 subsystem's cooling systems. The
remaining fan or fan canister will continue to provide cooling;
however, failure of this fan unit will result in the storage subsystem
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
1 |
Refer to the 'Component requiring service' field in the Details area.
If... |
Then... |
The component requiring service is
the fan canister |
Go to step 2. |
The component requiring service is
the power-fan canister 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. |
|
|
2 |
If the fan canister does not appear to be missing from the
storage subsystem, re-seat the fan canister in the enclosure by
removing it and reinserting it. |
4 |
If you are replacing the fan canister with a new unit, then
check the model of the fan canister you removed and ensure that the new
fan canister is the same model. If you do not have a canister that is the same model, contact your technical support representative.
|
5 |
Insert the new or original canister securely into place. |
6 |
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. |
