Background
Media Error, sometimes referred to as Medium Error, generally refers to that a hard disk encounters an uncorrectable sector in a read operation and cannot return accurate data to host, which corresponds to a SCSI protocol KCQ code of 03/11/xx. The generation of Media Error means that the data of the sector (LBA) cannot be read correctly even if the hard disk itself has exhausted all the Error-tolerant means (e.g., LDPC decoding, retry, etc.).
The current hard disk test has no test method for actively manufacturing the media error. In the test activity of the server, the pressure test is only carried out on the hard disk, and the condition that a bad block really appears in the hard disk is waited, so that the media error is caused. The passive test method cannot predict when the media error occurs and records the time; there is a side effect of consumption of hard disk life, requiring the emergence of media error to be accelerated by continuous pressure.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
The following explains key terms appearing in the present invention.
The BMC executes a server remote Management controller, which is called Basebard Management controller in English. The method can perform operations such as firmware upgrading, machine equipment checking and the like on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller as well as RAM for data storage, flash memory and firmware for non-volatile data storage, providing basic remote manageability in terms of secure remote restart, secure re-power-up, LAN alerts and system health monitoring. In addition to the basic IPMI function and system operation monitoring function, the mBMC enables selection and protection of BIOS flash devices by storing the previous BIOS using one of 2 flash memories. For example, when the system cannot be started after the remote BIOS is upgraded, the remote administrator can switch back to the BIOS image that worked before to start the system. Once BIOS is upgraded, BIOS image can be locked to prevent virus from invading it.
The essential reason for Media Error generation is that the read/write signal processing system of the hard disk cannot correctly decode the data signal read from the hard disk medium (e.g., the disk of an HDD, the NAND of an SSD). Several main reasons for Media Error are described below for HDD and SSD profiling, respectively. In order to reduce the occurrence of Media Error as much as possible, an extremely complex Error correction process and algorithm are provided in the hard disk to correct the original Bit Error (Raw Bit Error), so as to ensure that the user data can be correctly decoded. In terms of product specification, after a layer-by-layer error correction processing algorithm is carried out, the HDD UBER can reach 10-15, and the SSD UBER can reach 10-17. Unlike HDDs, SSDs have a complete set of error checking and recovery mechanisms inside, although they do not require complex analog-to-digital signal processing. After host reads data from NAND, there are several error correction steps such as ECC check, LDPC check, RAID check in disk, retry, etc. inside SSD to ensure correct data read. Only after all the means fail, the SSD reports the Media Error, informing host that the original data cannot be recovered.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the present invention. The execution subject in fig. 1 may be a hard disk injection medium error test system.
As shown in fig. 1, the method includes:
