Case:
IBM 3650 server, use 5 SAS 300GB disks as RAID5; the entire storage only divides one LUN, divided into 3 partitions, the first partition is the partition of the Windows 2003 system, and the second partition is the partition of the SQL Server 2010 production library.The third partition is a backup partition.
Solution:
The engineer broke all the disk away from the RAID environment and analyzed it in a safe way in safe storage.Analyze the combination parameters of all disks in the original RAID. In the analysis, it is found that the Disk No. 0 disk has been severely damaged, and it is the first offline disk. It is not necessary to repair. The No. 4 disk is an important data disk. The No. 4 disk is required.Can restore data.Engineers implement disk repair: After the 4 disk fixes are completed, according to the original RAID combination parameters analyzed, virtual reconstruction RAID.After the virtual RAID combination is completed, the three partitions on the original server can be identified normally and can see all files.The important SQL Server database file is restored, and it is attached to SQL Server for verification and viewing. No problems are found.
