Embodiment 1

[0043] In the default disk drive letter of the system, the path of the disk drive letter is / dev / sda. After triggering the udev rule, rename the disk device path name ( / dev / sda), and obtain the disk through udevadm test / sys / block / sda ID-path, and then generate a disk letter through a python script, the script is disk2slot.pyc, the script command is / usr / bin / python / disk2slot.pyc$env{ID_PATH}, and the disk letter generation binding character is P0B00S00, Then execute SYMLINK+="qdisk / $env{QDISK_SLOT} to link the disk device to the / dev / qdisk / directory, and the final disk device link is / dev / qdisk / P0B00S00.

Abstract

The invention relates to the technical field of computers, and discloses a method for binding disk drives of server. The method comprises the following steps of: (1) before system starting, inserting a disk at each slot position on a host; (2) in a system starting process, distributing corresponding system drives for the disks by a kernel, and distributing the disks by the kernel according to a sequence of scanning the disks; (3) binding a system drive with slot position information on a server by the system drive according to a kernel equipment manager rule file, sending a renaming message to the kernel by a kernel equipment manager, and modifying the system drive by the kernel according to the renaming message; and (4) binding the disks by the kernel equipment manager according to the system drive modified in the step (3) so as to form binding drives. According to the method, disk slot positions and drives are bound, and the disk drives used by Oracle ASM do not change after restarting, so that favorable stability is provided. Meanwhile, the method can support online disk change, so that the disk change is more convenient.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for binding a disk drive letter of a server. Background technique [0002] PYTHON language is an object-oriented, interpreted computer programming language. Nowadays, it is more and more used in the field of IT operation and maintenance automation. The advantage of PYTHON in system management lies in its strong development capabilities and complete tool chain. PYTHON has become a sharp weapon in the hands of operation and maintenance personnel. [0003] The kernel device manager (udev) is a function in the LINUX2.6 kernel. It replaces the original DEVFS and becomes the default device management tool for the current LINUX system. The kernel device manager (udev) exists in the form of a daemon process, and manages the device files in the / DEV directory by listening to the action events sent by the kernel. If there are multiple hard disks, during the system startup proc...
