Root Cause
1) During the DAE002 insert the system first time, the Controller B connect to the disk frame first. Hence the DAE labeled as DAE 999.
2) In a minute, the Controller A connect the disk frame ,so the DAE number changed to DAE 002
3) The history alarm about the DAE999 remain in the storage but the disk enclosure as been renamed to DAE002. Hence the alarm cannot recovered automatically.
Solution
Manually clear the alarm.
Suggestions

After deep analyzing there is no issue on the power supply in DAE002 and also in other disk enclosure. Suggest first to check the logs to find out the root cause. If the root cause is not related to hardware level we can clear the alarm manually.
