技术领域technical field
本申请涉及服务器技术领域，特别涉及一种服务器物理磁盘定位方法、装置、设备及介质。The present application relates to the technical field of servers, and in particular, to a method, apparatus, device and medium for locating a physical disk of a server.
背景技术Background technique
当前，对服务器中的物理磁盘进行定位的最简单有效的方法是利用系统内磁盘读写命令，如linux系统下使用dd命令对一块磁盘进行读写，磁盘上有对应的读写指示灯，运行dd命令时查看服务器磁盘的指示灯，指示灯闪烁则表示此磁盘在进行读写，以此定位磁盘的物理位置。At present, the easiest and most effective way to locate the physical disk in the server is to use the disk read and write commands in the system. For example, in the Linux system, use the dd command to read and write a disk. When using the dd command, check the indicator of the server disk. If the indicator flashes, it indicates that the disk is reading and writing, so as to locate the physical location of the disk.
虽然上述磁盘定位方法简单有效，能够非常直观的确定逻辑盘符对应的物理磁盘的位置，但是这种方案的缺点在于每轮磁盘读写操作只对一个磁盘进行读写，也即每轮读写操作只能确定一块磁盘的位置。当磁盘数量很多的时候，这种方案是非常费时的。Although the above-mentioned disk positioning method is simple and effective, and can very intuitively determine the location of the physical disk corresponding to the logical drive letter, the disadvantage of this solution is that each round of disk read and write operations only reads and writes to one disk, that is, each round of read and write operations. An operation can only determine the location of a disk. When the number of disks is large, this solution is very time-consuming.

当前，对服务器中的物理磁盘进行定位的最简单有效的方法是利用系统内磁盘读写命令对一块磁盘进行读写，磁盘上有对应的读写指示灯，运行dd命令时查看服务器磁盘的指示灯，指示灯闪烁则表示此磁盘在进行读写，以此定位磁盘的物理位置。虽然上述磁盘定位方法简单有效，能够非常直观的确定逻辑盘符对应的物理磁盘的位置，但是这种方案的缺点在于每轮磁盘读写操作只对一个磁盘进行读写，也即每轮读写操作只能确定一块磁盘的位置。当磁盘数量很多的时候，这种方案是非常费时的。为此，本申请公开了一种服务器物理磁盘定位方案，能够有效解决上述技术问题。At present, the simplest and most effective way to locate the physical disk in the server is to use the disk read and write commands in the system to read and write a disk. There are corresponding read and write indicators on the disk. When running the dd command, check the instructions of the server disk. The indicator light flashes to indicate that the disk is reading and writing, so as to locate the physical location of the disk. Although the above-mentioned disk positioning method is simple and effective, and can very intuitively determine the location of the physical disk corresponding to the logical drive letter, the disadvantage of this solution is that each round of disk read and write operations only reads and writes to one disk, that is, each round of read and write operations. An operation can only determine the location of a disk. When the number of disks is large, this solution is very time-consuming. Therefore, the present application discloses a server physical disk positioning solution, which can effectively solve the above technical problems.

需要指出的是，本实施例中，指示灯闪烁时，对应的二进制符合为1，指示灯不闪烁时，对应的二进制符号为0。It should be noted that, in this embodiment, when the indicator light is flashing, the corresponding binary coincidence is 1, and when the indicator light is not flashing, the corresponding binary symbol is 0.
下面，以linux系统下服务器的12块物理磁盘定位为例。假定磁盘逻辑盘符为sda、sdb、sdc、sdd、sde、sdf、sdg、sdh、sdi、sdj、sdk、sdl，以二进制将上述12块逻辑盘符编码如下表1所示：Below, take the location of 12 physical disks of the server under the Linux system as an example. Assuming that the disk logical drive letters are sda, sdb, sdc, sdd, sde, sdf, sdg, sdh, sdi, sdj, sdk, and sdl, the above 12 logical drive letters are encoded in binary as shown in Table 1 below:
表1Table 1
按照4位二进制编码，一共进行4轮物理磁盘读写操作，编码第一位为1的磁盘进行第一轮读写操作，编码第二位为1的磁盘进行第二轮磁盘读写操作，编码第三位为1的磁盘进行第三轮磁盘读写操作，编码第四位为1的磁盘进行第四轮磁盘读写操作。本例中四轮磁盘读写操作如下：According to the 4-bit binary code, a total of 4 rounds of physical disk read and write operations are performed. The first round of read and write operations is performed on the disk whose first bit is 1. The second round of disk read and write operations is performed on the disk with the second bit of 1. The disk whose third digit is 1 performs the third round of disk read and write operations, and the disk whose fourth digit is 1 performs the fourth round of disk read and write operations. In this example, the four rounds of disk read and write operations are as follows:

dd if＝/dev/sdh of＝/dev/zero&dd if=/dev/sdh of=/dev/zero&
dd if＝/dev/sdj of＝/dev/zero&dd if=/dev/sdj of=/dev/zero&
dd if＝/dev/sdl of＝/dev/zero&dd if=/dev/sdl of=/dev/zero&
执行以上四轮操作后能够得到四个物理磁盘指示灯闪烁的统计结果，根据编码可以分析得到下表2，由此可以得到所有物理磁盘对应的位置。以上编码方式可以扩展到任意多个磁盘，根据二进制编码的原理，n位编码能够表示2的n次方个不同的符号，因此对于服务器的k个磁盘来说，只需要floor(log2k)+1轮(其中floor表示向下取整函数)操作就能够将服务器中的所有物理磁盘全部完成定位。After performing the above four rounds of operations, the statistical results of the flashing indicators of the four physical disks can be obtained. According to the code, the following table 2 can be obtained by analysis, from which the corresponding positions of all physical disks can be obtained. The above encoding method can be extended to any number of disks. According to the principle of binary encoding, n-bit encoding can represent 2 to the nth power of different symbols. Therefore, for the k disks of the server, only floor(log2 k) +1 round (where floor represents the rounding down function) operation can complete the positioning of all physical disks in the server.
