Background
In a complex computer system such as a server, a storage system and a switch, the monitoring management subsystem is a key module thereof and is used for recording fault logs, system operation logs and the like, the log records need accurate time consistent with a service system, the monitoring management subsystem is usually in a local area network, and time checking of the system is carried out through public network time without a method, so that a time checking mechanism with the service system needs to be set.
In the current scheme, the Time of the service system is stored in an RTC (real_time Clock). Windows typically stores the local time, i.e., the local time obtained by adding the local time zone time to the 0 time zone time, in the RTC, and the monitoring management subsystem accesses the RTC and uses the time stored in the RTC as the local time of the monitoring management subsystem. However, in Linux, unix, mac, and other systems, UTC (Universal Time Coordinated, coordinated universal time) time, that is, 0 time zone time is stored in the RTC, and time zones are stored in a system configuration file, and the monitoring management subsystem directly uses the time stored in the RTC as the local time of the monitoring management subsystem, so that a situation that the time cannot be aligned with the service system may occur.
In summary, how to effectively perform accurate time synchronization of the computer management subsystem is a technical problem that needs to be solved by those skilled in the art.

Detailed Description
The core of the invention is to provide a time synchronization method of a computer management subsystem, which realizes accurate time synchronization of the computer management subsystem.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a method for time synchronization of a computer management subsystem according to the present invention, the method for time synchronization of a computer management subsystem may include the following steps:
step S101: the time stored in the RTC is acquired.
The time stored in the RTC is typically written by the OS (Operation System) through a fixed interface after the start-up. The RTC may be accessed by the computer management subsystem, and in practical applications, it may be generally set to be accessed periodically, that is, in a specific embodiment of the present invention, step S101 may specifically be to obtain, according to a preset period, a time stored in the RTC, so that the computer management subsystem may periodically perform updating of the local time thereof. Of course, in other cases, other updating methods may be set as needed.
The computer management subsystem of the application is independent of the service system, and in practical application, the computer management subsystem in the BMC can be generally specified. Of course, other computer management subsystems with time synchronization requirements can also apply the scheme of the application to realize accurate time synchronization. When the computer management subsystem is specifically a computer management subsystem in the BMC, a program may be set in the BMC, and then the time stored in the RTC may be directly or indirectly acquired, for example, in a specific case, based on the Intel architecture, the RTC may be indirectly accessed through the ME or the BIOS, so that the time stored in the RTC is acquired.
Step S102: and acquiring a local time zone and a service system time mode.
In addition to obtaining the time stored in the RTC, the computer management subsystem needs to obtain the local time zone and the service system time mode to achieve accurate time synchronization.
In a specific embodiment of the present invention, step S102 may specifically be:
and acquiring the local time zone and the service system time mode input by the user through the first interface. The first interface may be, for example, an IPMI interface provided by a computer management subsystem, or a setup interface, or a Redfish interface, so that the user may perform local time zone and business system time mode input.
In a specific embodiment of the present invention, step S102 may specifically be:
and acquiring a local time zone and a service system time mode which are automatically transmitted by the OS through a second interface.
In this embodiment, the OS is code-adjusted to automatically send the local time zone and the service system time mode to the BMC, considering that if the local time zone and the service system time mode are input by the user, the operation is more complex and the efficiency is lower.
The type of the second interface may be set as required, and may be, for example, an LPC interface, or a USB interface.
In addition, since the conventional standard OS issued by each OS vendor cannot realize automatic transmission of the local time zone and the service system time mode, one executable program may be set to be installed in the OS, and it should be applicable to the mainstream OS such as Windows, linux, etc., or different executable programs may be set for different OS, considering that the mainstream OS has different types such as Windows, linux, etc., as long as the object of step S102 in this embodiment can be achieved.
In a specific embodiment of the present invention, step S102 may specifically be:
the local time zone and the business system time pattern stored in the first storage medium are obtained.
In this embodiment, considering that the local time zone is usually stored in the system configuration file, the computer management subsystem cannot conveniently and directly access, and if in the foregoing embodiment, the OS is adjusted so that the OS automatically sends the local time zone and the service system time mode, the implementation is more complicated, so in this embodiment, a first storage medium storing the local time zone and the service system time mode is specially set, and the computer management subsystem can conveniently obtain the local time zone and the service system time mode by accessing the first storage medium.
There are various specific implementations of the first storage medium, and in one specific embodiment of the present invention, the first storage medium may be specifically a first storage medium that is expanded in the RTC.
In this embodiment, the RTC is extended and the local time zone and the business system time pattern are stored in the extended memory space. The computer management subsystem may periodically perform the acquisition of three parameters, namely, the time stored in the RTC, the local time zone, and the service system time mode, by accessing the RTC, e.g., periodically.
In addition, it should be noted that, the local time zone and the service system time mode stored in the RTC after expansion may be generally written by the OS, for example, the OS periodically performs time stamping, where the local time zone and the service system time mode are written, and the time stamp is the time stored in the RTC.
In another embodiment of the present invention, the first storage medium may be a first storage medium other than RTC and connected to the OS and the computer management subsystem. For example, the first storage medium is specifically selected as EEPROM (Electrically Erasable Programmable read only memory, electrically erasable and programmable read only memory), which can be configured on a motherboard for storing local time zones and service system time modes, and which also needs to be connected to the OS and the computer management subsystem. The OS may write at start-up or periodically during run-time to the local time zone and business system time patterns. The computer management subsystem is coupled to the first storage medium, e.g., periodically accessed, for local time zone and business system time pattern acquisition.
Step S103: when the acquired service system time mode is a default time mode, overlapping the acquired time stored in the RTC with a local time zone to obtain the local time of the computer management subsystem; when the acquired service system time mode is a local time mode, taking the acquired time stored in the RTC as the acquired local time of the computer management subsystem.
When the acquired service system time mode is the default time mode, the time stored in the RTC at this time is indicated to be the time of 0 time zone, so that the local time of the computer management subsystem is obtained by superposing the acquired time stored in the RTC with the local time zone, taking the local time zone as an east 8 zone as an example, and the local time of the computer management subsystem can be obtained by adding 8 hours to the acquired time stored in the RTC.
And if the acquired service system time mode is a local time mode, the time stored in the RTC is the time overlapped with the local time zone, so that the acquired time stored in the RTC is directly taken as the acquired local time of the computer management subsystem.
By applying the technical scheme provided by the embodiment of the invention, after the computer management subsystem acquires the time stored in the RTC, the time is not directly used as the local time of the computer management subsystem, but the local time zone and the service system time mode are further received and acquired. When the time mode of the service system obtained by receiving is the default time mode, the time stored in the RTC at the moment is indicated to be 0 time zone time, so that the obtained time stored in the RTC is overlapped with the local time zone, and the accurate local time of the computer management subsystem can be obtained. When the acquired service system time mode is the local time mode, it is indicated that the time stored in the RTC is already the time after the 0 time zone time is overlapped with the local time zone, so that the acquired time stored in the RTC can be directly used as the acquired local time of the computer management subsystem. In summary, the solution of the present application enables accurate time synchronization of the computer management subsystem.
