Case:
The server consists of 3 hard disks for RAID5. The machine room staff found that the server could not start, and the after -sales detection was contacted. Two hard disks could not be recognized.After the after -sales processing, the hard disk that can be recognized in the RAID controller can be recognized.But RAID still fails, and there are more than 200 SQL2005 databases on the server.Because it is an old customer, customers know that they cannot do any processing, and immediately get the original hard disk to the server data to restore the company.
Solution:
Data recovery engineer testing, there is a hard disk with a bad disk and cannot be read.After verification calculation, calculate this hard disk data, and virtually produces all parameters such as RAID block size, pan -smooth, and direction.Restore the data successfully.The whole process was only two hours. After confirming the customer technology, the two hundred databases were completely complete without any damage.Data recovery successfully.
