Embodiment Construction

[0022] In the prior art, after the ARM device performs a power-on operation, the ARM device will automatically run the program stored in the BIOS, and the program records the hardware directly connected to the extended peripheral component interconnect express (PCIe) motherboard. Such as hard disk, network interface, keyboard, serial port, parallel port, etc.; then read the initial Master Boot Record (MBR) information from the BIOS, and the ARM device will read from a certain partition of the device according to the MBR information. To load the boot loader (Boot loader), wherein the loader stores information about the operating system (OS), such as the name of the operating system, the location of the operating system kernel (kernel), etc. The operating system kernel is used to manage the hardware resources of the computer , acts as an interface between software and hardware, and any operation on the operating system must be communicated to the hardware through the kernel; then...

Abstract

The embodiment of the present invention relates to a disk management method and device in an ARM device, and the ARM device. The method includes the ARM device receiving configuration information, the configuration information including the corresponding relationship between the slot number of the disk and the startup sequence; updating the configuration information according to the configuration information The preset device tree source code DTS file, the DTS file before the update includes the SAS controller, hardware interface and slot number associated with each disk, and the updated DTS file includes the SAS controller associated with each disk , hardware interface, slot number, and startup sequence, and convert the updated DTS file into a device tree block DTB file; according to the SAS controller, hardware interface, and slot number associated with each disk in the DTB file The corresponding relationship with the startup sequence scans and starts the disk, thereby solving the problem of inflexible configuration and poor versatility caused by the disk management method in the ARM device in the prior art.

Description

technical field [0001] The invention relates to the communication field, in particular to a disk management method and device in an ARM device in the server field and the ARM device. Background technique [0002] ARM (Acorn RISC Machine, ARM) processor is a processor with small size, low power consumption, low cost, and high performance. Because it supports Thumb (16-bit) and ARM (32-bit) dual instruction sets, it can be well Compatible with 8-bit and 16-bit devices, and the addressing mode is flexible and simple, making ARM devices configured with ARM processors more and more widely used. [0003] The ARM processor integrates the function of the Serial Attached SCSI (SAS) controller. The SAS controller is used to manage the disk through the SAS protocol. In order to simplify the design and control cost of the SAS controller, the SAS controller does not have a traditional The firmware (Firmware) of the disk array (Redundant Arrays of Independent Disk, Raid) card in the X-86...
