Demo unit Huawei Storage S5600T stuck in Safe mode .
After investigatiing , i found out that the controller B was not powering on properly due to the power loss .
After some power issues with the environment , the safe mode issue appeared.
Please try to remove both controllers from the enclosure and wait for 30 seconds. After that please insert controller B and wait for 5 minutes . After that please power the system on and see if this works fine . If it does then insert the other controller. This solved the problem. Both controllers powered on OK.
