Remove and insert a controller with even force. Excessive force may damage the
appearance or connectors of the controller.
Remove only one controller at a time to ensure service continuity.
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.
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.
If both controllers of a controller enclosure fail, contact Huawei technical support for
assistance.
