Abstract
The invention discloses a method for guaranteeing management mainboard time by virtue of cooperation of an NTP and an RTC chip and relates to the computer management technology. The accuracy of the management mainboard time is guaranteed by use of NTP time and time in the RTC chip; under the circumstances of network connected and normal NTP server, the network time is synchronized from the NTP server, and if the synchronization is successful, an NTP service is invoked by use of a cron service period to synchronize the network time as the system time of a rack management controller (RMC) on the management mainboard; in addition, the time synchronized from the NTP server is written in the RTC chip; in case of a network fault or abnormal operation of the NTP server, the time is read from the RTC chip as the current system time. The method guarantees the correctness of the time of a log recorded by the RMC to the whole cabinet hardware equipment faults and maintenance operations, and therefore, the operation and maintenance operating personnel can effectively process the out-of-order hardware accurately without delay.
Description
Technical field
The present invention relates to computer management technology, is exactly that a kind of NTP and RTC chip coordinates the method guaranteeing to manage the mainboard time specifically.
Background technology
Along with the development of computer technology, server centered monitoring management technology is applied more and more extensive in practice, realizes server node bulk supply, integral heat sink and integral monitoring management in whole machine cabinet.The equipment being responsible for monitoring management in whole machine cabinet hardware set is called RMC(Rack Management Controler), generally can use ARM controller and Embedded Linux System, be integrated on one piece of management mainboard, be responsible for the monitoring management of whole machine cabinet.RMC wherein important function be in real-time monitoring server node, node the health status of the hardware device such as plate, fan, power supply and the various events of generation (as the Action Events of attendant, as pluggable node, plug fan, turns off power supply, amendment node IP address etc.).Hardware device is once break down or operating personnel have done some operation, and RMC can carry out record by the mode of log daily record in real time, and uploads syslog server.The time of event and event generation is contained in log record, machine room operation management personnel judge rapidly the time of hardware device and the device damage damaged by the log daily record that RMC records, carry out necessary process in time, ensure the security of operation of whole machine cabinet and stablize.
If the time of RMC is incorrect, then the fault time in the log recorded and the time of origin of event also incorrect, operation maintenance personnel is difficult to exact time that accurate failure judgement occurs and carries out necessary process targetedly.Therefore, need a kind of reliable mechanism to ensure the correctness of RMC time, ensure that the fault log time is accurate, whole machine cabinet fault is processed timely and effectively.
Summary of the invention
The present invention is directed to the weak point that prior art exists, provide a kind of NTP and RTC chip and coordinate the method guaranteeing to manage the mainboard time.
A kind of NTP and RTC chip of the present invention coordinates the method guaranteeing to manage the mainboard time, the technical scheme solving the problems of the technologies described above employing is as follows: the method mainly utilizes the time in NTP time and RTC chip to guarantee to manage the correctness of mainboard time, at network-in-dialing and ntp server under normal circumstances, from the ntp server synchronizing network time, if synchronously success, the NTP Service synchronized network time is called by the cron seeervice cycle, as management mainboard on centralized monitor administrative unit RMC(Rack Management Controler) system time, and in the time write RTC chip of synchronously returning from ntp server, when network failure or ntp server irregular working, then from RTC chip, read the time as present system time, the method mainly comprises two parts: start and call NTP service, RMC reading time from RTC chip.
Preferably, start NTP service during the upper electric-opening of described startup and call NTP service and refer to: RMC simultaneously, synchronously network time is obtained from ntp server, after completing startup, amendment crontab script, use NTP service from the Network Synchronization time by cron service timing, if synchronously success, then call stime () and RMC system time will be set to lock in time.
Preferably, described RMC reading time from RTC chip refers to: the RTC chip of RMC outside is used for time storage and timing uses, and RMC can read its timing time by I2C interface from RTC chip.
A kind of NTP and RTC chip of the present invention coordinates guarantees that the beneficial effect that the method managing the mainboard time compared with prior art has is: the mechanism that the method is cooperatively interacted by NTP service and RTC chip, carry out the correctness of strict guarantee RMC system time, thus guarantee the correctness of RMC to the log time of whole machine cabinet hardware device fault and attended operation record, O&M operating personnel can effectively be processed faulty hardware timely and accurately.
Accompanying drawing explanation
Accompanying drawing 1 is that described NTP and RTC chip coordinates the flow chart guaranteeing the method managing the mainboard time.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the method guaranteeing to manage the mainboard time is coordinated to further describe to a kind of NTP and RTC chip of the present invention.
A kind of NTP and RTC chip of the present invention coordinates the method guaranteeing to manage the mainboard time, by using NTP (Network Time Protocol, NTP (Network Time Protocol)) serve and RTC (Real-Time Clock, real-time clock) chip coordinate ensure management the mainboard time correct, the time in NTP time and RTC chip is mainly utilized to guarantee to manage the correctness of mainboard time, at network-in-dialing and ntp server under normal circumstances, from the ntp server synchronizing network time, if synchronously success, the NTP Service synchronized network time is called by the cron seeervice cycle, as management mainboard on centralized monitor administrative unit RMC(Rack Management Controler) system time, and in the time write RTC chip of synchronously returning from ntp server, when network failure or ntp server irregular working, then from RTC chip, read the time as present system time.
Embodiment 1:
A kind of NTP and RTC chip described in the present embodiment coordinates the method guaranteeing to manage the mainboard time, need NTP to serve and RTC chip coordinates and ensures the correct of RMC system time, the method specifically comprises and starts and call that NTP serves, RMC reads time two parts from RTC chip.
This NTP and RTC chip coordinates in the method guaranteeing to manage the mainboard time, start NTP service during the upper electric-opening of described startup and call NTP service and refer to: RMC simultaneously, synchronously network time is obtained from ntp server, after completing startup, amendment crontab script, use NTP service from the Network Synchronization time by cron service timing, if synchronously success, then call stime () and RMC system time will be set to lock in time.
This NTP and RTC chip coordinates in the method guaranteeing to manage the mainboard time, and described RMC reading time from RTC chip refers to: the RTC chip of RMC outside is used for time storage and timing uses, and RMC can read its timing time by I2C interface from RTC chip.
NTP and RTC chip of the present invention coordinates the method guaranteeing to manage the mainboard time, the signal of its flow process is as shown in Figure 1: start NTP during the upper electric-opening of RMC simultaneously and serve, RMC monitors whole machine cabinet hardware state, use NTP service from the ntp server synchronizing network time by cron service, if synchronously success, then NTP is set to RMC system time lock in time, NTP is write RTC chip lock in time simultaneously; If synchronization failure, then RMC reads the present timing time from RTC chip, is set to RMC system time.
