Media information: RAID0 of 6 disks, old hard disk of Fujitsu, SCSI interface Fault description: The client description server is doing RAID0, in which the fifth disk is offline, the other disks are green, and the system crashes. Troubleshooting: The customer takes 6 hard disks to the data center, and the raid data recovery engineer takes priority to detect the faulty disk No. 5, and the hard disk is not powered, and the board is faulty. Then, the remaining 5 hard disks were tested one by one, and an amazing result was obtained. All the hard disks showed a state of no power supply, and the circuit board was faulty. The customer is not very convinced of such a conclusion. It is very firm that only one hard disk is offline before it is taken, and the others are in a normal green state. In order to dispel the customer's doubts, Das engineers conducted the following further in-depth tests: a, replace the RAID card According to previous experience, some SCSI hard disks are more likely to be picked up, and there will be no recognition after connection. b, use a multimeter to measure the circuit on the PCB board The measurement found that the fuse of the near power chip was damaged. Verifies our previous correct judgment of the fault. Data recovery process and results: After the fault is determined, after communicating with the customer, find the corresponding spare parts PCB for circuit fault repair, then clone the data for each hard disk, and finally perform the underlying analysis and data reorganization of the image file. Since the amount of data is not particularly large, after half a day, the data extraction is completed and 100% recovered. to sum up: 1, the information provided by the customer can be referred to, but can not be blindly recognized, requires the rigorous analysis and judgment of the engineer. 2, to the customer's suggestion: For the customer, pay attention to the usual maintenance, the appearance of the appearance does not necessarily reflect the real situation, in the operation and maintenance, you need to check the status of the server from multiple aspects to avoid unnecessary losses. .
