Case:
Dell PowerEdge T710 can be equipped with up to 16 hard disks, and the memory capacity can reach up to 144GB, which is the best choice for large capacity operations.The T710 design method that meets customer needs provides excellent system versatility, and adopts neat and reasonable components and power configurations to facilitate fast installation and simplify deployment operations.There are 8 plates on the server for a set of RAID6. Among them, the No. 1 and No. 5 disk are bright red lights. They were not found in time. Later, the 2nd plate was turned on. The real array collapsed.Windows 2008 Server.
Solution:
The engineer was tested after the hard disk, and the disk faulty occurred on the No. 1 and No. 5 disk.A small amount of hard disk bad sectors appear on the 2nd plate, which can be mirror.Other hard disk mirrors are smooth.Because the entire server 8 plates do a set of RAID6, theoretically lacking two disks can restore data. Whether the data is correct depends on the sequence of damage to the Disk No. 1 and No. 5 and No. 2.The disk and No. 5 disk are bad first, and the No. 2 plate is later bad. The recovered data should be correct. Unless the small disadvantage of the No. 2 disk has an impact on the data, most data should be normal.
