Examples of further illustrations are: the invention can be matched with two servers, one local server to be tested is used as a remote control terminal, the other remote control server is used as a local terminal to be tested, and whether the network of the remote control terminal and the local terminal to be tested supports the IPv4 or IPv6 address or not is checked. And the two servers can normally communicate without abnormal IP mutual ping. And the BMC Web interface can be normally logged in according to the BMC IP of the local server, no error log or exception exists, if error information or an exception BMC log is generated, the fault reason is artificially analyzed and solved, and the normal BMC IP network is ensured.

Related information of BMC, BIOS, serial ports of OS and baud rate of the remote control terminal and the local terminal to be tested in the testing process is configured well, and the consistency of serial port network connection is kept.

The method comprises the steps of inputting ipmitool sol info 1/8 under a local terminal to be tested, wherein 8 represents a sharing port, 1 represents a management port, and the ipmitool sol info 1/8 can be viewed separately. The command is used for checking the baud rate of the serial port network, and different server baud rate standards are inconsistent. Taking the shared port as an example, setting the serial port baud rate to be 115200, and after the setting is successful, continuously inputting the ipmitool sol info 8 to check whether the shared port baud rate is changed to be 115200.

The method comprises the steps that a serial port is directionally set under a BIOS, a local terminal to be tested enters the BIOS interface according to delete when a starting interface is selected in the restarting process of the local terminal to be tested, the serial port interface is found in a column of an ADVANCED interface serial port, the local terminal to be tested has two serial port types of COM0 and COM1 or only one serial port type, the default starting serial port is ensured to be consistent with the actual serial port and consistent with the default serial port types of a system and a BMC, the SOL connection communication can be normally ensured, the Baud rate is checked and set to be 115200, the transmission type is VT100+, the SOL connection cannot have a messy code phenomenon under the type, other transmission types can have partial messy codes, the test effect can be influenced, and the local terminal to be set and quit after being.

Different operating systems are different in configuration file types in serial port orientation setting, and the Linux system serial port redirection setting and kernel printing information acquisition and storage are as follows by taking a Redhat 7 series system as an example: the RHE7.0 series began using grub2, so the serial port configuration was greatly different from other RHEL versions.

The setup here mainly involves the modification of one file:

the specific configuration steps are

1) Add console ttys1,115200n8 console ttys1 to/etc/default/grub and delete rhgb set:

GRUB_CMDLINE_LINUX＝"console＝ttyS1,115200n8 console＝tty1"；

2) the "grub2-mkconfig-o/boot/grub2/grub

3) reboot, the restart OS is in effect.

tty1 represents that the serial port state is com1, tty0 represents that the serial port state is com0,115200 and represents the set baud rate, and the configuration information should be consistent with the serial port states under the BIOS and the BMC.

Checking the BIOS state and the system condition by out-of-band connection sol;

the method comprises the steps of inputting ipmitool-I lan plus-H IP-U user-P password sol activity out of band, inputting IP as a server BMC IP, and inputting user and password as BMC user name and password, and then returning to establish sol network communication remotely after inputting the instruction. When the local system restarts the os, the remote SOL end can normally synchronize the POST startup and shutdown interface of the system, can log in and check the bios interface, enter the local system os, can check the temperature and voltage information of the relevant sensors, the BMC hardware equipment information and the like under the system, and can also input the relevant instructions of the server startup and shutdown and the like.

And the out-of-band execution of ipmitool-I lan plus-H ip-U user-P password SOL deactivating can disconnect the SOL communication state and terminate the serial port network communication.

The script is used for out-of-band self-checking SOL connection state, the Sol self-checking script generates a corresponding test log, and whether connection is normal or interrupted or not, whether transmission rate is abnormal or not and the like can be effectively checked according to the self-checking test log. And the out-of-band self-checking test log information analyzes the connectivity and stability of the serial port network, and if a fault occurs, the fault is analyzed, processed and solved in time.

After the out-of-band sol self-check test is successful, the local server executes a local test tool, decompresses the sol _ local _ stress, runs a script/sol _ start in the tool, tests the local sol network with default pressure testing time of 24h, automatically finishes the time pressure testing, generates a corresponding test log, and analyzes whether each data of the network is normal or not, and whether an error log and a messy code exist under the local sol network pressure testing according to the test log.

Meanwhile, after an SOL environment ipmitool-I lan plus-H IP-U user-Password SOL activate is configured and enters a SOL system, the remote server also executes a remote test tool, decompresses the SOL _ remote _ stress, inputs an IP address into a file. And then executing a SOL _ start, carrying out SOL network pressure test by a remote server, wherein the default time is 24h, automatically stopping the pressure test when the time is reached, generating a corresponding test log, analyzing the stability of the serial port network, the transmission rate of the network, the network delay and the packet loss condition under the SOL remote pressure test according to the test log, and if the fault occurs, analyzing the fault problem according to the generated test log file and solving the fault problem.
