Case:
The RAID dual followers composed of 6 300G SAS interface hard disks are paralyzed by the office system due to the loss of the database and unable to run.
Solution:
Our engineer first pulled out the hard disk and tags in order; detected the 6 fast hard disk, and found that two of the hard disks were not powered on; after the PC-300 was testedThe hard disk operates one by one; the virtual RAID array is composed of manual computing; the data is finally exported; after verifying the data, the array data is successfully restored.
