Case:
The HP ML160 server of a group company is responsible for the operation of the company’s business system. During the use process, accidents caused the server to be unable to start. After reporting, it was detected by the HP manufacturer engineer. Due to the long period of use of the server, the electronic components were found to be damaged and the HBA card was damaged.The array management interface found that the array information collapsed, and the 2nd plate reported an error. The entire server data could not be accessed!Data to be restored: All data of the server, the focus is the financial database of UFIDA.Find the data recovery center for help.
Solution:
After receiving the three hard disks sent by the staff of a group company, the company attaches great importance to the situation after the staff explained that the company’s basic situation is as follows: the server has a total of 3 160g SATA hard disks, and the array level: RAID5 Server operating system: Windows2003Server has a total of 4 partitional file system formats in the format of NTFS recovery and recovery. The member disk meets the condition of the normal mirror sector under the recovery tool! 2. Put the server members No. 0 and use the Winhex tool software under the company’s data resumption machine. Backup of the entire physical sector 3, the server member No. 1, (the logical structure of the No. 1 is damaged) at the company’s data resumption of the company’s data resumption Under the work machine, the Winhex tool software is carried out. The backup of the entire physical sector, 4, server member No. 2 has a bad session! Processing plan: After the Dustless Room is cleaned and repaired, the Russian professional recovery equipment PC3000 for UDMA is used to resume the sector to save all the physical sector information images of the fault plate to the intact medium superior. 5. Analyze the array parameters, block size, and rotation method. Because the service model is relatively old, the early array management method of Corbali is used, that is, the dual -cycle data management method of COMMAQ. This is relatively complicated when the data restructuring is recovered! 6. Finally, use professional data restructuring software, and use the three backup disks based on the analyzed array parameters, the virtual original server array environment, and carry out data reorganization for 5 hours! And exported all the data files after a day of emergency rescue, the data recovery result: The original partition of the server is four partitions: C partition, the 20G file system format NTFS data occupies space 9GB D partition: 100g data occupies space 12.6GB E partition: 100g occupation occupied Space 16.3GB F partition: 80G data occupies 2.92GB and finally successfully restores all the data in the server
