Case:
The hard disk ST3300657SS sent by the industry customers, 3 hard disks yellow lights, and the server is paralyzed.
Solution:
There are 11 hard disks, Seagate 300G SAS interface hard disks, model ST3300657SS, and three faulty hard disk customers have been marked.After testing, the three hard disks marked are indeed bad.The other 8 hard disks are intact.First of all, 8 mirroring hard disks. After the mirror is completed, the data analysis of the 8 mirror disk is analyzed. This is a set of 10 -set RAID5, and one of the 11 hard disks is a hot disk.It has been broken at the same time, and there is a hot presence.Only by repairing all the three hard disks as much as possible and mirroring, can the best data that can restore the effect and the most correct data of the institution.After the efforts of engineers, all 3 fault -hard disks have mirror data.After correctly eliminating the heat disk and the first hard disk, the remaining 9 mirror reorganization RAID5 was successful.
