Case:
Customers are a total of 6 disks of a technology company’s IBM X3650 server, and the RAID5 of 5 disk groups. One of them is a hot disk, and the other is an independent hard disk without offline.Can’t find RAID in the server.No one in the Oracle environment in the system will be built, and the system is required to run in the original environment.
Solution:
1. Data recovery center engineers removed each hard disk in order to detect each hard disk, and the results were normal. 2. The engineer performs a full mirror of the underlying sector on all the original disk to further ensure the security of the original data; 3. Merge the data underlying analysis of the image files that are done later to determine the RAID combination method; Perform the data combination reorganization and extract; 5. Insert the image of a single plate to the server for RAID reconstruction. To restore the good RAID image to the server, the system is successfully started, and the Oracle environment can run. When the server disk array cannot be started, remember not to operate blindly. The blind operation of the data is too risky, and sometimes it can even cause all data to be completely destroyed and cannot recover. Usually use the RAID process to make a timely backup of important data, and the maintenance discovery of RAID should be replaced in a timely manner.
