Case:
The RAID0+1 composed of 8 146G SAS interface hard disks. Multiple disks are lost at the same time, so that the office system cannot run normally. Customers then contact our engineers and did not perform other operations. We immediately fixed disk.
Solution:
Our engineer first draws out the hard disk and mark it in order; detects the 8 146G SAS interface hard disk, and finds how fast the hard disk has a physical bad tract.; Eventually export data; after verifying the data, the array data is successfully restored.
