Case:
A HP server of Mr. Long, a RAID5 composed of 5 146G 2.5 -inch SAS hard disks. The array collapsed and the array information was lost.
Solution:
The engineer first did the hardware test of the 5 hard disks, the magnetic head of the 5th plate was damaged, and the No. 4 disk had a physical bad sector. The other 3 hard disks had no hardware problems.In accordance with the principle of easy to difficult, first deal with the problem of bad disks No. 4 hard disk, make a complete mirror of hard disks 1, 2, 3, and 4, and then lack the No. 5 hard disk to analyze the array parameters of the HP dual -cycle with the mirror hard disk.The array is successful. The export data is not fresh. It is the data of last year. It shows that No. 4 hard disk is a hard disk with a relatively earlier line. The No. 5 hard disk processing data must be recovered.From the matching accessories of the No. 5 hard disk with the accessories library, the opening of the trading head in the dustless laboratory in our center is replaced. The 5th hard disk processing is very successful. After the full mirror image is made, the lack of No. 4 hard disk re -virtual platform to build a array successfully, and the export is exported.The data verification is correct, the data is complete, and 100%successful.
