Case:
IBM System X3850 X5 server, 8 Windows operating system IBM hard disk, the interface type is SCSI, forming RAID5, all hard disk reported DDD, the hard disk has a bad sector after the detection, and RAID collapses.
Solution:
The engineer backup hard disk data, during the backup process, found that the hard disk had a bad sector, and used a bad channel solution to repair the bad sectors; analyzed all the hard disk mirrors that have been fully backup to determine the original structural parameters of the fault RAID, and judge the fault at the same time.The offline situation of each hard disk in RAID; based on the analysis of the RAID parameters and the offline hard disk situation, build RAID data in only read the environment, and conduct a basic logical verification of the virtual RAID built.Full mirror; complete the complete logic analysis and verification of the RAID image of the backup production. If the file system in the image is still inconsistent, it will be repaired according to the solution of the corresponding file system damage until the data needed by the user.
