This fault can be completely rectified only by upgrading the product version. The temporary solution is to communicate with customers and inform them that they need to accept incomplete system logs if they need to use the LUN copy function. If customers do not need to use the LUN copy function, they can suspend the LUN copy process according to the following procedure:
Step 1 Log in to the CLI.
Step 2 Run the debug command and type the password to enter the debug mode.
Step 3 Type mml to go to the human-computer interactive interface.
Step 4 Run the cpy settimer off command.
Step 5 Wait for a while and collect the logs again. Check whether the log information can be stored more than one minute.
