Case:
Customer describes the RAID5 made by 6 SCSI 73G hard disks of HP arrays. There is a plate of coil, pulling it back and inserting it back to the indicator light to become a normal green light.The hard disk of the array can no longer be recognized. There is an important system on the storage, and the departments below cannot submit the data up.
Solution:
The engineer received the six SCSI hard disks on a PC Server in a single disk and found that a hard disk could not be identified. Further detection and found that the hard disk magnetic head was damaged.The five hard disks that can be recognized can be used by North Asian mirroring tool by Disk Image to complete the hard disk to the newly prepared security storage.During the backup process, a small number of bad disks were found in the backup process, and it was found that it did not affect the data tracked in the disadvantaged area.Analyze RAID information through the structural characteristics of the file system, remove the bad hard disk, and build a virtual RAID environment.The discovered files include the latest SQL Server database file, exported and attached to the SQL environment, and there is no error error in database DBCC detection.The hard disk that can judge the damage to the magnetic head is an early -line hard disk.It is normal to introduce all data into the newly prepared storage of customers, and there is no problem with client access.
