Case:
The server cannot enter the system, and RAID information is wrong.
Solution:
The HP server data recovery engineer preliminarily inspected the RAID5 with four 300G SAS hard disks. Customers did not replace the bright red light hard disk in a normal use and caused the array to collapse.There is no physical failure after the professional equipment is tested.So the HP server data recovery engineer used professional software to reorganize RAID, and finally the server data recovered successfully.
