Detailed Description
In order to make the objects, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the 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 application.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
The application relates to a remote debugging method of a switch in a blade server chassis, which mainly aims at the switch in the blade server chassis.
The blade server case refers to a case of a blade server, and a plurality of blade servers are arranged in the blade server case, wherein each blade server is a card server unit which can be inserted into a rack-type case with a standard height, and the card server unit usually only comprises a system mainboard and does not comprise a network port or a network card; the blade servers are connected to and communicate with an external network through switches integrated within the blade server chassis.
Taking the blade server enclosure 101 shown in fig. 1 as an example, the blade servers such as the blade server 1012 and the blade server 1013 are connected to an external network (a second network shown by a dotted line) through a portal (a second portal) of the switch 1011 integrated in the blade server enclosure.
When the switch has an error, the user may use the remote debugging client 102 to remotely debug the switch 1011 through the network (i.e., the second network connected through the second network port) to which the switch 1011 itself is connected, so as to obtain various required debugging information. However, when the second network fails, the second network cannot be connected to the switch for remote debugging, and only the serial port of the switch connected on the spot to the machine room can be used for reading data for local debugging, which is very inconvenient.
Typically, a management module circuit board, such as management module circuit board 1014 shown in FIG. 1, is also disposed within the blade server chassis. The management module circuit board 1014 is mainly used to collect hardware information of various components in the blade server chassis 101, including the blade servers 1012, 1013, and the like, so as to monitor and manage the blade servers. In addition, the management module circuit board 1014 may also monitor the operation of power supplies, fans, switch components within the blade chassis. Since the management module circuit board 1014 can obtain the bottom layer information of the blade server and operate the blade server, the management module circuit board 1014 is not connected to the switch 1011 in the blade server chassis and is connected to the second network.
To facilitate remote management and control, the management module board 1014 is provided with a separate portal (second portal) and is connected to a second network isolated from the first network through the portal to secure the system. The remote management client 103 is connected to the management module circuit board 1014 through a first network, acquires information related to each blade server through the management module circuit board 1014, and acquires remote monitoring and management of each blade server through the management module circuit board 1014.
Therefore, the inventor of the application creatively thinks that if the connection can be established between the management module circuit board and the serial port of the switch, the related debugging information of the switch can be acquired through the first network when the second network fails.
Based on the above inventive concepts, in an embodiment of the present application, the present inventors have modified the blade server enclosure 101 shown in fig. 1 to obtain the blade server enclosure 201 shown in fig. 2.
As shown in fig. 2, in the blade server chassis 201, a connection is established between a serial port of the switch 2011 and the management module circuit board 2014, so that the management module circuit board 2014 can send a debug command to the switch 2011 through the connection with the serial port of the switch 2011, and read debug information returned by the switch 2011.
In this way, the remote debugging client 202 can be connected to the management module circuit board 2014 through the first network when the second network fails, and can remotely debug the switch 2011 through the management module circuit board 2014.
The remote management client 203 can still be connected to the management module circuit board 2014 through the first network, obtain the related information of each blade server through the management module circuit board 2014, and obtain the information for remotely monitoring and managing each blade server through the management module circuit board 2014.
In another embodiment of the present application, the functions of the remote debugging client 202 may also be incorporated into the remote management client 203, and the remote debugging command is sent by the remote management client 203, so as to implement remote debugging on the switch 2011 without specially setting the remote debugging client 202.
Specifically, in the management module circuit board 2014, the method as shown in fig. 3 is performed to enable remote debugging of the switch 2011.
Referring to fig. 3, an embodiment of the present application provides a method for remotely debugging a switch in a blade server chassis, where the method includes: operation S310, converting a remote debug command received from a first network, which is isolated from a second network to which a switch is connected, into a local debug command; operation S320, sending the local debug command to the switch through the serial port connection established with the switch; operation S330, receiving a debugging result returned by the switch in response to the local debugging command through the serial port connection; in operation S340, a debugging result is returned through the first network.
In operation S310, the first network is a network in which the management module circuit board in the blade server chassis is connected through a network port on the management module circuit board. The first network is isolated from the network to which the switch is connected through the network port on the switch, i.e., the second network. When the second network fails, the first network is not affected and can still work normally.
The remote debug command is a debug command sent to a port of a management module circuit board in the blade server chassis, and is typically a network packet conforming to a certain network protocol.
The local debugging command is a debugging command which can be sent to a serial port of the switch in the blade server chassis.
In operation S320, the serial port connection established with the switch, similar to the serial port connection established with the switch in the field when the first network fails to enter the machine room, is connected to a serial port, such as a console port, for performing debugging, feeding back debugging information, and outputting the operating state of the switch. After the serial port connection is established, the switch may be debugged through the serial port connection, and a debugging result returned by the switch in response to the local debugging command may be received through the serial port connection in operation S330.
Then, in operation S340, the debugging result may be returned to the client sending the remote debugging command through the first network, so as to complete the debugging of the switch in the blade server chassis.
Therefore, even if the second network connected with the switch in the blade server chassis has a fault, the remote debugging of the switch can be realized through the first network connected with the management module circuit board in the same blade server chassis, and the remote debugging of the switch can be realized without entering a machine room and being connected to the serial port of the switch on the spot for local debugging.
According to the remote debugging method for the switch in the blade server chassis, the probability of entering a machine room to carry out local debugging on the spot can be greatly reduced, so that the maintenance cost of the blade server is greatly reduced, the condition for timely and quickly repairing the switch error is provided, the time for the switch to operate with the error is correspondingly shortened, and the use efficiency of the switch in the blade server chassis is greatly improved.
In addition, since the first network is generally a more secure management network and is more private than the second network, remote debugging of the switch via the first network is also more secure. Therefore, even when the second network does not have a fault, the remote debugging method of the switch in the blade server chassis can be used for realizing safer debugging.
It should be noted that the embodiments shown in fig. 2 to fig. 3 are only basic embodiments of the remote debugging method for the switch in the blade server chassis according to the present application, and an implementer may further perform refinements and extensions based on the above embodiments to obtain an embodiment that meets specific implementation requirements and implementation conditions.
Fig. 4 shows a specific implementation manner of implementing a remote switch debugging method in a blade server chassis according to another embodiment of the present application.
Referring to fig. 4, in the management module circuit board in the blade server chassis of the present embodiment, an embedded controller (for example, an ARM controller) is provided, and three services are operated in the controller: a serial port driver service 401, an IPMI service 402, and a network communication service 403.
The serial port drive service 401 is mainly used for sending a local debugging command and reading a debugging result returned by an exchanger through a serial port connection established with the exchanger in the blade server chassis;
the IPMI service 402, also called an Intelligent Platform Management Interface (Intelligent Platform Management Interface) service, is mainly used for implementing interaction with a remote debugging client through an IPMI protocol, and the remote debugging client may send a remote debugging command to the ipmitool tool through the ipmitool tool and receive a corresponding debugging result.
The network communication service 403 is mainly used for receiving a remote debugging command sent by the IPMI protocol and sending a debugging result packaged according to the IPMI protocol.
The three services can respectively serve the own roles and focus on a certain function, and when problems occur, the three services can be independently repaired and updated, so that the maintenance cost is reduced. The embedded controller is used for operation, so that better operation performance can be obtained, and the method is conveniently realized through an embedded program.
Specifically, the main process of the method for remotely debugging the switch in the blade server chassis according to the embodiment of the present application, as shown in fig. 5, includes:
step S5010, receiving an IPMI network packet from the first network;
specifically, a network data packet from the first network is received by the network communication service 403. Thereafter, the network communication service 403 passes the received network packet to the IPMI service 402, and the processing by the IPMI service 402 is continued.
The IPMI network packet is usually a SOL format packet.
Step S5020, obtaining equipment parameters appointed by an IPMI network data packet;
in the embodiment of the present application, the IPMI service may also receive other commands that are commonly used to remotely monitor and manage other components of the blade server.
Therefore, after receiving the network packet delivered by the network communication service 403, the IPMI service 402 further determines whether the IPMI network packet is for remotely debugging the switch inside the chassis. Specifically, the IPMI network packet is used for remotely debugging the switch in the blade server chassis or remotely monitoring and managing other components of the blade server by specifying the device parameters in the IPMI network packet.
However, specifying device parameters is not the only way to determine whether an IPMI network packet is a remote debug command, and an implementer may specify any other parameter, such as a value of a flag in the network packet, to indicate that the network data is for remotely debugging a switch in the blade server chassis.
Step S5030, determining whether the first network data packet is a remote debug command according to the first parameter, if yes, continuing step S5040, and if not, switching to another management command processing flow;
step S5040, analyzing the network data packet to obtain a local debugging command according to the IPMI protocol;
in the embodiment of the present application, analyzing the network data packet to obtain the local debug command mainly refers to analyzing the network data packet according to the SOL format to obtain the local debug command, for example, "interface VLAN-interface 1" (enter management VLAN).
It should be noted that, in the embodiment of the present application, the steps S5020 to S5040 are all performed by the IPMI service 402
Step S5050, sending the local debugging command to the switch through the serial port connection established with the switch;
specifically, the IPMI service 402 converts the analyzed local debugging command into serial port data, sends the serial port data to the serial port driver service 401, and sends the serial port data to the blade server chassis internal switch through the serial port connection by the serial port driver service 401.
specifically, the serial driver 401 reads the switch serial data and sends the serial data to the IPMI service program 402.
Step S5070, packaging debugging results according to an IPMI protocol;
specifically, after receiving the serial port data of the switch, the IPMI service program 402 converts the serial port data into the SOL format according to the IPMI protocol, and obtains an encapsulated SOL data packet. The IPMI service 402 then passes the encapsulated SOL packets to the network communication service 403.
Step S5080, return the second network packet.
Specifically, the encapsulated SOL packet is returned by the network communication service 403 to the ipmitool client that sent the debug command.
Thus, the debugging process of the switch in the blade server chassis is completed once.
Before executing the remote debugging process, the embodiment of the present application further needs to establish a serial connection with the switch in advance, and configure the serial connection, including a baud rate, a data bit, a parity bit, and the like. After the configuration of the serial port is completed, serial port data can be sent to the serial port of the switch through the serial port driver service 401, and the serial port data returned to the serial port of the switch can be received.
In addition, because the blade server machine case that this application embodiment used, the switch serial ports that management module circuit board is connected are the serial ports of management and debugging switch, for example, the console mouth. The switch sends the management information and the state information of the switch to the serial port in real time. For example, when the switch enters a new state or a new stage, the switch can timely send the entered new state or the new stage to the serial port; when the switch has an error, the switch can send error information and running environment information with the error to the serial port in time.
Therefore, in the embodiment of the present application, in addition to receiving and processing the remote debugging command sent by the user from the remote debugging client through the above steps S5010 to S5080 to complete remote debugging of the switch in the blade server chassis, the received serial data actively sent by the switch is stored in the local first log file through the serial connection during daily operation. The first log file may be a log file which is recorded with daily operation and exists in the management module circuit board, or may be a log file which is specially established for the switch in the blade server chassis. And the required debugging information can be found more quickly by establishing the log file for the switch in the blade server chassis.
The first log file is viewable or downloadable through a browser login management module Web interface. Thus, in an embodiment of the present application, the network communication service 403 may also respond to a request from the first network to download the first log file and send the locally stored first log file to the remote debugging client.
In this way, when a switch has a problem, the state information of the switch in the adjacent time period when the switch has an error can be acquired through the first log file, so that the root cause of the error can be more easily positioned, and the time for positioning as the problem can be further shortened.
It should be noted that the embodiments shown in fig. 4 to fig. 5 are also only exemplary illustrations of the remote debugging method for the switch in the blade server chassis according to the present application, and do not limit the implementation and application scenarios of the embodiments of the present application.
