Check the hardware.
Log in to the storage system on the OSM. Query the hardware faults in the system fault history or logs, but no matched result is found. View the indicators of hardware components (such as hard disks), and all indicators are in the Normal
The I/O applications to hard disks are normal, and the storage system runs properly. Therefore, the wrong report must not be caused by a hard disk fault.

Connect the storage system to the HyperTerminal by using a serial port cable, and then log in to the storage system.
Enter the debug mode.
Run the mml
Run the dev sesstartlight 1
