Case:
Around December, Hangzhou Data Recovery Center received a RIAD5 IBM server disk recovery project from a university in Hangzhou. The server operating system was CentOS, with a total of 6 300GSAS hard disks.
Solution:
Analysis of data recovery engineers found that the server disk array collapsed and data was damaged.Further analysis found that there were 4 hard disks in the six hard disks, so there was no major problem, so this 4 hard disk was made to mirror.In the remaining two hard disks, it was found that the No. 0 hard disk and No. 3 hard disk occurred in physical faults, the No. 0 hard disk motor had a failure, and the No. 3 hard disk body appeared serious physical bad sectors, which caused these two hard disk data to be unable to read.Pick.After the two hard disks are repaired successfully, the two hard disks will be made.By analyzing and analyzing the image, it lasted about 4 days, and finally the disk array data was successfully recovered.
