Case:
The Dell server is composed of 12 300G SAS hard disks, and the RAID5 of 11 plates is added with a heat preparation.Lost, the array collapsed,
Solution:
After the engineer tested the hard disk, it was found that the 5 and 6 hard disks had physical bad disadvantages. After processing the 5 and 6 hard disk mirrors, it was found that the No. 7 hard disk circuit board was damaged. After the restoration, the array parameters began.They were all messy. The investigation was that their new employees wanted to restore the array and inserted the hard disk.After the engineer analyzed the sequence of the hard disk and the parameters of the array, the data of the virtual reorganization array was intact, and then let go of it. Because the customer did not find us to recover the data at the same time, it would have a certain damage to the scene.Normally, it should be analyzed for 5-10 hours. Later, it took two days to analyze the results. In addition, the 1500GB oversized Oracle database file recovery time.
