HP server dual loop system fails to start data recovery successful

Case:
After the two hard disks of the HP server are on, the server is restarted and cannot enter the system; the customer’s server’s use environment is poor, so it is placed on the warehouse floor and blows with two fans.

Solution:
Detecting the No. 0 disk found that the hard disk was abnormal, the firmware could not be written, the plate was found to be severely scratched, and there were a lot of dust.Try to analyze the combination with RAID missing status; the double-loop of the HP server, the analysis block size (128SEC*16) and the sequence MISS-2, re-combined, the data is 100%successful, and the customer is very satisfied.
