The following explains key terms appearing in the present invention.
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 system for locating a downtime phase for a server.
As shown in fig. 1, the method includes:
Optionally, as an embodiment of the present invention, the method further includes:
if the BIOS is not burnt before the shutdown of the server, the BIOS is burnt on a normal server which is configured with the shutdown server after the shutdown of the server, and the serial port log and the BMC log for comparison are acquired after the normal startup.

In order to facilitate understanding of the present invention, the method for locating the downtime of the server according to the present invention is further described below with reference to the principle of the method for locating the downtime of the server according to the present invention and the process of managing the server in the embodiment.
Specifically, the method for locating the downtime phase by the server includes:
the embodiment can effectively provide the direction for converging the downtime problem, assist in positioning the abnormal point of the downtime problem, and make up the problem that in the downtime problem processing process, due to difficult recurrence and long recurrence period, serial port logs cannot be acquired in a short time to effectively position, so that the problem solution period is prolonged, and the difficulty is increased.
1. The BMC is used as a substrate management controller, can monitor information such as temperature, voltage, a fan, a power supply and the like of a hardware system, realizes corresponding adjustment, ensures that the system is in a good working state, and can record hardware information and a server running log when in use. In the power-on self-test process, the BMC is used as an independent system for performing platform management, does not depend on other hardware on the mainboard but can also interact with the BIOS, so that the whole power-on self-test process is monitored, specific positions synchronously record the change of power-on self-test codes through the BMC and generate logs, and the change in the power-on self-test process and the stage at the moment can be effectively tracked.
2. Generally, the downtime problem mainly occurs in a process from startup to entering a server system, i.e., a power-on self-test process. As shown in fig. 2, in this process, the server runs by means of the BIOS code, and sequentially performs operations such as initialization, loading, and access to each part of the server hardware system, where the BIOS operation is implemented by means of the called related function. In the process, a mark position for marking the current operation can appear, and the real-time output can be carried out through 8-position LED lamps on the mainboard and an external display system in real time. In the whole power-on self-test process, as shown in fig. 3, each operation performed by the BIOS, including but not limited to the stages of self-test of the CPU, self-test or loading of the memory, driver loading, and device initialization, will continuously output a corresponding flag bit, and each flag bit will represent the currently performed operation and the stage where the operation is performed.
3. As shown in fig. 4, in addition, different devices are often used in cooperation with a motherboard of the same model of server to form different configurations. However, in the power-on self-test process, the power-on self-test codes of the servers in the same configuration are changed consistently, that is, the sequence of various initialization operations and drive loading is completely consistent.
4. In this embodiment, a one-to-one correspondence relationship between the power-on self-test code and the current power-on self-test state of the server needs to be established, so that the location where the server is down, that is, the operation being performed, can be effectively determined. The power-on self-test stage or the loaded drive corresponding to each flag bit is confirmed by importing a special version of BIOS to collect a log record with sufficient detail on an original machine station or a server configured to normally work.
5. And confirming the stage and operation of the server at the moment by the power-on self-detection code at the downtime recorded in the BMC log captured by the downtime server machine, thereby reducing the investigation range, providing a solution idea and shortening the debugging time.
