Case:
Customer is a data service provider. The server is HP EVA6400 disk array. The storage has a total of 144 1T hard disks. Earlier in the storage that cannot be used normally, Ungroup has 4 hard disks.The yellow lamp alarm, but the storage can be used normally. When the 16th plate starts the yellow lamp alarm, the storage can no longer be accessed.
Solution:
After the engineer of the Data Recovery Center took over 16 damaged hard disks, first stickers of all hard disks on all hard disks. The hard disk body and the hard disk bracket were labeled. The purpose of this work was to always maintain the hard disk dial bodyThe unity of the bracket is not disrupted.After the label is pasted, the modified optical fiberic hard disk mirror equipment is used to perform four groups of mirror work on the hard disk. This working time is longer, 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 of independent research and development of the hard drive that has completed the mirror.Put the repaired bad disk and reinsert the cabinet. The engineer analyzes the data structure of the EVA. For this EVA, write a special data recovery program, use the program to move all the data out, and the data is 100%recovered successfully.
