Case:
HP EVA6400 disk arrays, storage of a total of 144 1T hard disks. Earlier in the storage that cannot be used normally, Ungroup has 4 hard disks. After 4 hard disks are out, there are 15 disks yellow lights to report to the police, but storage is okay.Used normally, when the 16th plate starts the yellow light alarm, the storage can no longer be accessed.
Solution:
After the engineer took over 16 damaged hard disks, first label all the special labels on all hard disks. The hard disk body and the hard disk bracket were labeled each.Unity is not disrupted.After the label is posting, the hard disk is used to work with the hard disk with a modified optical fiber hard disk mirror device modified by North Asia. This working time is long, each time, usually about 8 hours.After the mirror is completed, the software will generate a mirror statement, including whether the image is completed, whether there are bad sectors, and the logical block address report of the bad sector.Repair the repair software independently developed by North Asia with a bad drive that has completed the mirror.The fixed bad drive has been inserted back to the cabinet. North Asian engineers analyze the data structure of EVA. In response to this EVA, write a special data recovery program, use the program to move all the data out, and the data is 100%recovered successfully.
