Case:
The customer is a RAID5 composed of 4 300G SAS hard disks. In normal use, the hard disk that does not replace the bright red light in time causes the array to collapse.A HP DL380G7 server cannot enter the system, RAID information is wrong.
Solution:
No physical failure was found by detecting 4 hard disks, and directly analyzed the array information against the hard disk. The unique dual -cycle computing method of HP should analyze the two sets of array operation parameters of large cycles and small cycles.The verification is correct, and then the virtual reorganization array information is made, and the data is successfully recovered.
