Run show system server_port server_name=SSH to check whether the SSH port ID is 22.
If the port ID is not 22, run change system server_port server_name=SSH port_num=22
to change it to 22.
If the controller to be replaced is in minisystem state (After login to the CLI of
the controller, Storage: minisystem> is displayed), run the showbootmode
command to check whether the boot mode of the storage system is normal.
– If the command output is boot -> boot_osp, the boot mode is normal.
Find the cause of the fault and rectify the fault before replacing the
controller.
– If the command output is boot -> boot_rescue, the boot mode is
abnormal. Run the resumebootmode command to restore the boot
mode to normal before replacing the controller.
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.
A controller must be replaced within ten minutes. Otherwise, the system heat
dissipation is compromised.
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 engineers for assistance.
If the FRU tool fails to identify a controller fault, skip
Step 8.
