Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments These are part of the embodiments of this application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Currently, after the BIOS detects that the network card PXE ROM is turned on, it will put the network card PXE as the boot device in the Bootoption option. The Boot option of the BIOS will set the boot sequence according to the attributes of the boot device, such as Boot option#1, Boot option#2, Boot option#3,..., Boot option#n, etc. It is generally set according to customer needs. For example, Boot option #1 is set to the OS boot disk, Boot option #2 is set to the network card PXE boot device, and Boot option #3 is set to CD/DVD, etc. Currently, the BIOS startup item can implement the startup device polling mechanism, that is, Bootoption#1 has no startup device or the startup device fails to start, polling to Boot option#2, if there is no device model, polling to Boot option#3, and then to Boot option #n's boot device, if there is no device or the startup fails, then boot from Bootoption#1, and repeat polling until a bootable device is found. However, when the network card device is not in Bootoption#1, according to the current polling mechanism, if there is a bootable device before polling the network card device, the BIOS will stop polling and start directly with the boot device, which is not conducive to the deployment of the server system. .

To solve the above problem, please refer to Figure 1. Figure 1 is a flow chart of a network card device polling method provided by an embodiment of the present application. The method includes:

S101: Receive device polling instructions;

This step is intended to receive device polling instructions. The so-called device polling instructions are BIOS polling for startup devices. It should be noted that the device polling command is not necessarily an actual command, but can be a command triggered by other actions. For example, when the server is powered on and started, according to the startup process, the BIOS will automatically perform polling after powering on. At this time, the BIOS is equivalent to automatically generating the device polling instructions in this step. Of course, the device polling instruction can also be generated by the server, for example, a corresponding device polling instruction is generated according to the configuration set by the user to perform a server restart, etc.

The command type, content and structure of the device polling command are not limited here. As long as the command can cause the BIOS to poll and start the boot device, it can be used as the device polling command in this step. It should be noted that the device polling command can specify a certain interface or number of startup devices to be started first. For example, when the boot devices of Boot option#1, Bootoption#2, and Boot option#3 are all in place, you can set Boot option#2 as the first target of polling.

S102: Determine whether the network card independent polling option in the BIOS configuration interface is enabled; if so, enter S103; if not, enter S104;

This step requires determining whether the separate polling option for the network card is enabled in the BIOS configuration interface. By default in this embodiment, before performing this step, the network card independent polling option has been configured in the BIOS configuration interface. There are no specific restrictions on how to configure the network card independent polling option. You can add the network card independent polling option in the BIOS configuration interface and configure the IPMI command set for the network card independent polling option. That is, the independent polling option of the network card can be controlled through the IPMI command set, which enables or disables the independent polling option of the network card.

If the network card independent polling option is enabled, proceed to step S103; if not enabled, proceed to S104.

S103: Search for the network card device in the startup device and use the network card device as the only startup item;

This step is intended to search for the network card device in the startup device and poll only for the network card device after the network card independent polling option is enabled. In other words, only use the network card device as the startup device to start the server. Specifically, during the execution of this step, each startup device can be detected one by one, and whether each startup device is a network card device can be judged. Usually there will be at most one network card device in the server. After the network card device is detected, the network card device can be polled and started. It should be noted that the essence of this step is to first search and confirm the network card device, and then poll the network card device individually. That is, although the server contains other network card devices at this time, after the network card independent polling option is enabled, other network card devices will be considered to be absent. bit, which means that only the network card device in the server can be used as a startup device, and other startup devices are not polled. For example, among Boot option#1, Boot option#2, and Boot option#3, only Boot option#3 is the network card device. Then search for Boot option#1, Boot option#2, and Boot option#3 one by one to confirm Bootoption# 3 is the network card device. At this time, only Boot option #3 is polled, so that the network card device can be used as the only startup item to start the server.

On the basis of this embodiment, as part of the embodiments of this application, after the execution of this step, you can also start the network card device, connect to the remote server, download and install the boot image from the remote server, so as to realize the installation and deployment of the server operating system. or updated. And since the operating system usually only needs to be deployed when the server is first started, after downloading and installing the boot image from the remote server, you can also turn off the network card independent polling option and configure the default boot device. This is so that the server will not use the network card device as a separate polling object during subsequent normal use, which facilitates the normal startup of the server. Of course, if the server later needs to use the network card device as the startup device, it can still be set by enabling the network card independent polling option.

S104: Poll all boot devices and start the server.

If the network card independent polling option is not enabled, the boot device in the server will be polled normally. That is, all boot devices in the server participate in polling. In this step, you can poll all boot devices in order of their device numbers and start the server. That is, polling is performed in the order of Boot option#1, Boot option#2, and Boot option#3, or polling can be performed in the set order. However, no matter how polling is performed, when the independent polling option of the network card is not enabled, it is necessary to ensure that all startup devices can be polled. However, during the actual polling process, not all startup devices will be polled. Once the appropriate startup device is polled, the server will start in a timely manner.

In addition, the network card independent polling option can be configured with default settings. For example, the server manufacturer can set the network card independent polling option to enabled by default when the server leaves the factory. Then when deploying the server for the first time and performing server system debugging and maintenance, you can only Poll the network card device to avoid involving all startup devices in polling, which may cause the server to not start with the network card device, thus affecting the system deployment progress.

In the embodiment of this application, by configuring the network card independent polling option in the BIOS configuration interface, when the network card independent polling option is enabled, polling control can only be performed on the network card device. When the network card independent polling option is turned off, the network card independent polling option can be started in the normal order. Device polling. This can avoid other startup devices from affecting the startup of the network card device when the network card device is not in the first order, and reduce the failure rate of the PXE network automatic deployment system.

Based on the above embodiment, as a preferred embodiment, whether it is necessary to perform the initial deployment of the system after the server is powered on, or for remote update or debugging of the server system, the individual polling option of the network card can be enabled or disabled in real time according to the IPMI command. .

Of course, it is easy to understand that before enabling or disabling the individual network card polling option according to the IPMI command, you must also add the network card individual polling option in the BIOS configuration interface and configure the IPMI command set for the network card individual polling option.

It should be noted that there is no established execution relationship between enabling or disabling the independent polling option of the network card according to the IPMI command and receiving the device polling command in step S101 in the previous embodiment. That is, you can receive the device polling command first and then receive the IPMI command. The IPMI command can also be received first and then the device polling command can be received, or even both can be received at the same time, but it is usually executed before step S101. Due to the different functions of the two, that is, the device polling command is used to guide the start of polling, while the IPMI command is used to control the individual polling options of the network card. That is, after starting polling, you still need to select and execute the previous implementation based on the content of the IPMI command. Step S103 or step S104 in the example.

The IPMI command is used to control the enabled status of the network card's individual polling option. This embodiment does not limit its specific structure and content. Preferably, see Figure 2, which is a schematic diagram of the structure and content of an IPMI command provided by this application. . The IPMI command shown in Figure 2 includes multiple groups of bytes, where 0 in the request dat represents disabled, indicating that it is not started, and 1 represents Boot only, which is only for individual polling of the network card device. Of course, those skilled in the art can also use other forms or structures of IPMI instructions, which should all fall within the protection scope of this application.

The operation and maintenance of the server can be facilitated through the IPMI command. The IPMI command refers to the out-of-band IPMI command. It can be generated by the server itself or sent to the server through other terminal devices to change the polling method of the BIOS when the server starts. Combined with the previous embodiment, as part of the embodiments of this application, after the BIOS receives the polling, it can detect whether the IPMI command is received. If not, polling is performed according to the enabling result of the current network card independent polling option. If received, polling is performed based on the enablement result of the separate polling option for the network card in the IPMI command.
