Method, system, terminal and storage medium for identifying HBA card model of server

Technical Field

The invention relates to the technical field of servers, in particular to a method, a system, a terminal and a storage medium for identifying the HBA card type of a server.

Background

The HBA (host Bus adapter), a host Bus adapter, is a circuit board or integrated circuit adapter that provides input/output (I/O) processing and physical connections between a server and a storage device. Because the HBA relieves the host processor of the data storage and retrieval tasks, it can improve the performance of the server. An HBA and its associated disk subsystem are sometimes collectively referred to as a disk channel.

HBAs are used in storage systems to connect computer internal buses to storage networks. The HBA is the physical connection between the I/O channel inside the server and the I/O channel of the storage system. The most commonly used internal server I/O channels are PCI and Sbus, which are the communication protocols that connect the server CPU to peripheral devices. The I/O channel of the storage system is actually a fibre channel. The role of the HBA is to translate between the PCI or Sbus and FC protocols, which are internal channel protocols.

In view of the unique advantages of HBA cards, the M5 platform began to introduce HBA cards, but there are two problems that exist:

1) it is not possible to distinguish between 16G and 32G.

2) It is not possible to distinguish between single or double ports.

Without obtaining accurate model information of the HBA card, the HBA card cannot be programmed with appropriate task load bearing capacity, which may cause resource waste or overload operation of the HBA card.

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 derived by a person skilled in the art from the embodiments given herein without making any creative effort, 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.

BIOS is an abbreviation of English "Basic Input Output System", and the name of Chinese after translation is "Basic Input Output System". It is an industry standard firmware interface for IBMPC compatible systems. It is a set of programs solidified on a ROM chip on the internal mainboard of computer, it stores the most important basic input and output program of computer, self-checking program after starting up and system self-starting program, it can read and write the specific information set by system from CMOS. Its primary function is to provide the lowest level, most direct hardware setup and control for the computer. In addition, the BIOS provides some system parameters to the operating system. The change of system hardware is hidden by BIOS, and programs use BIOS functions rather than directly control the hardware. Modern operating systems ignore the abstraction layer provided by the BIOS and directly control the hardware components.

An Intelligent Platform Management Interface (Intelligent Platform Management Interface) is originally an industrial standard adopted by peripheral devices of an enterprise system with an Intel architecture. IPMI is also an open free standard that users can use without paying additional fees. IPMI can span different operating systems, firmware and hardware platforms, and can intelligently monitor, control and automatically report the operation status of a large number of servers, so as to reduce the cost of the server system.

The double linked list is also called double linked list, and is one kind of linked list, and each data node has two pointers pointing to direct successor and direct predecessor. Therefore, starting from any node in the doubly linked list, its predecessor and successor nodes can be easily accessed. Generally we construct a bi-directional circular linked list.

FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a server HBA card type number identification system.

step 130, identifying a first parameter from target PCIE device information, where the first parameter includes a sub device identification code, a sub device manufacturer identification code, and a corresponding device type and a corresponding message type;

and 140, summarizing and storing the identified first parameters to the doubly linked list, sending the summarized first parameters in the doubly linked list to the BMC, and identifying the model of the HBA card by the BMC according to the local second parameters and the received first parameters.

In order to facilitate understanding of the present invention, the method for identifying the server HBA card model provided by the present invention is further described below with reference to the principle of the method for identifying the server HBA card model of the present invention and the process for identifying the server HBA card model in the embodiment.

Searching for a target PCIE device by taking the PCIE device name related to the first parameter as a keyword; and clearing the PCIE equipment information except the target PCIE equipment information.

Since there are many PCIE devices in the server, it is necessary to determine a target PCIE device, that is, to use a target PCIE device name related to the HBA card as a keyword, and then search for target PCIE device information from the PCIE device information scanned in step S1. And eliminating PCIE equipment information which does not need to be identified except the target PCIE equipment information. The target PCIE device information may include information of a plurality of PCIE devices.

Therefore, the data processing amount can be reduced, and the data processing efficiency can be improved.

And calling data of the bidirectional linked list, sequentially sending information in the linked list to the BMC according to an ipmitool command format agreed with the BMC, releasing resources in the linked list, and exiting the HBA card type number identification program and prompting that the bidirectional linked list is empty if the bidirectional linked list is empty.

The BMC receives an ipmitool command sent by the BIOS. And analyzing information of each field related to the PCIE according to the protocol content. And identifying information of the PCIE equipment by combining information such as VID, DID and the like according to the SID and the SVID, and displaying the information in an equipment list of the BMC according to the identified information.

When scanning a PCIE device, the BIOS needs to transmit an SID (sub-device identifier, which is a secondary code of a device authorized to be manufactured) and an SVID (sub-device vendor identifier, which is an identifier of a secondary manufacturer authorized by a PCI-SGI organization, and is a unique vendor identifier and does not allow duplication) to the BMC, and when the BIOS transmits these two pieces of information to the BMC, the BMC analyzes the information of the device in combination with VID (device vendor) and DID (different device types/model information of the same vendor), and displays the information in a device list of the BMC, and a user can query all configuration information of the device according to the displayed information, where the configuration information includes detailed model information.
