Case:
The HP DL380 G7 server, using RAID5 made by 4*1T SAS. At a certain time, a hard disk turned on red light, and the customer did not replace the hard disk in time, causing the array to collapse.
Solution:
The engineer puts the data of each disk to mirror, and no bad disk is found in the hard disk; the structural characteristics of the file system analyze the RAID information, remove the bad hard disk, and build the virtual RAID bad realm; detect the data, and then introduce all the data to the customer’s new new customer.The preparation storage is completely normal.
