Problems solved by technology

In this case, the Firmware in the form of a file cannot be loaded by the iSCSI HBA. Because the iSCSI protocol processing function is implemented in the Firmware file, if the iSCSI HBA fails to load the Firmware file during initialization, it does not have the iSCSI protocol processing function, resulting in failure. missing, not working

Embodiment Construction

[0019] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims of the present invention.

[0020] now refer to figure 1 , which shows the overall flowchart of the initialization method of the iSCSI host bus adapter (HBA) of the present invention.

[0021] First, a subkey is created in the registry of the operating system (step 102). For example, create a subkey under the registry branch corresponding to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control, and this subkey is loaded before the iSCSI HBA. Here, the location of the created subkey can be identified during the startup process of the operating system, that is, the operating system can see the registry content of the corresponding location.

[0022] Then, save the...

Abstract

The invention discloses a method and device for initializing an iSCSI (Internet Small Computer System Interface) host bus adapter. The device comprises an establishment module, a storage module and a first loading module, wherein the establishment module is used for establishing a subitem in a registration form of an operating system (OS); the storage module is used for storing a firmware file required by initializing the iSCSI host bus adapter into the subitem of the registration form; and the first loading module is used for reading the firmware file from the subitem of the registration form so as to initialize the iSCSI host bus adapter when the OS is started and the drive of the iSCSI host bus adapter is loaded. The invention can realize the smooth initialization of the iSCSI host bus adapter in an OS starting stage.

Description

technical field [0001] The invention relates to a host bus adapter device, in particular to an initialization device and method for an iSCSI host bus adapter. Background technique [0002] SCSI (Small Computer System Interface over Internet) HBA (Host Bus Adapter) is an intelligent device with a RISC (Reduced Instruction Set Computing) processor, which can According to specific requirements, the firmware (Firmware) files required for initialization are dynamically loaded. The Firmware file is generally only saved on the hard disk in the form of a file. [0003] In the startup phase of the Windows system, the loading order of each driver is: first load the driver of the SCSI (Small Computer System Interface, Small Computer System Interface) adapter type, and then load the file system. The iSCSI HBA is a SCSI adapter, so it will be loaded before the file system. In this case, the Firmware in the form of a file cannot be loaded by the iSCSI HBA. Because the iSCSI protocol pr...
