Precautions
l Remove and insert a controller with even force. Excessive force may damage the
appearance or connectors of the controller.
l Remove only one controller at a time to ensure service continuity.
l A controller must be replaced within a specific range of time. Otherwise, the system heat
dissipation is compromised.
– For Dorado5000 V3 (NVMe) and Dorado5000 V3 Enhanced Edition (SAS), a
controller must be replaced within three minutes.
– For Dorado5000 V3 (SAS), a controller must be replaced within five minutes.
l If a single controller fails, use the SmartKit to replace it when the other controller is
working properly. If the entire controller enclosure has been powered off, power on the
functioning controller before replacing the faulty one.
l If both controllers of a controller enclosure fail, contact Huawei technical support for
assistance.

Procedure
Step 1 Check status before replacement.
1. Check system status.
Start SmartKit and choose Home > Storage > Routine Maintenance > Health Check.
On the Health Check page, perform inspection as instructed. For details, see 5.1.2
Checking System Status.
NOTE
If some items fail in the inspection, rectify the faults by performing the recommended actions in
the inspection reports. Ensure that all other parts except the parts to be replaced are working
properly.
2. Optional: Check the status of the parts to be replaced.
Start SmartKit and choose Home > Storage > Parts Replacement > Parts
Replacement. On the Parts Replacement page, click FRU Replacement. Then
complete the check before the replacement as prompted. For details, see 5.1.3 Replacing
an FRU.
NOTE
If the FRU tool fails to identify a controller fault, skip this step and perform Step 2 to Step 11 to
replace the faulty controller manually.
You can proceed to next steps only when all items pass the pre-replacement check and the
replacement page is displayed. If any item fails, rectify the fault as prompted.
