Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 obvious that the described embodiments are some embodiments of the present application, but not all 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.
Referring to fig. 1, fig. 1 is a flowchart of a repairing method for expander die-hang provided in an embodiment of the present application, where the repairing method includes:
s101: when the CPLD detects that the expander chip is hung up, the CPLD generates a preset value in a CPLD register;
in general, the expander chip may be hung up due to software bug or excessive service pressure. There is no limitation on how expander die hang is detected. Preferably, the CPLD can judge whether the expander chip is dead according to an output signal of the expander chip, and when the output signal is a square wave signal, it is determined that the expander chip works normally; and when the output signal is continuously high level or continuously low level, determining that the expander chip is hung up.
During the normal operation of the Expander chip, a square wave signal (also called a heartbeat signal or simply a heartbeat) with a certain frequency is continuously output through one pin of the chip, and the CPLD can judge that the Expander chip normally operates by checking the signal output by the Expander. If the expander is hung, the thread cannot apply for the use authority of the chip processor, the corresponding pin cannot be operated to perform level turnover, the expander cannot continuously operate the chip pin to output high and low levels, and at the moment, the square wave signal is lost and externally shows a long-term high level or a long-term low level.
Once the expander chip is detected to be hung, the CPLD generates a preset value in the CPLD register of the CPLD, and the generation of the preset value mainly refers to the modification of a numerical value corresponding to the register. It should be noted that the preset value can be generated by a register at a preset position in the CPLD register. . I.e., which register in the CPLD is committed to indicate the expander chip status. The CPLD and the BMC can agree a special value to indicate that the expander chip is hung up, for example, the 1 st register of the CPLD is 0xA5 to indicate that the expander chip is hung up, and the default value is 0xFF to indicate that the expander is normal. When the CPLD checks that the expander heartbeat signal is lost, the register is operated and 0xA5 is written.
S102: the CPLD starts to time for a preset time, and the expander chip is electrified again after the time is over;
the step mainly re-powers the expander chip. The CPLD has the function of monitoring signals, and the CPLD and the expander can approximate the frequency of heartbeat, such as 1Hz, in the development stage. Thus, the CPLD checks the heartbeat signal of the expander once per second, and if the heartbeat is absent, the CPLD can determine that the expander is in the hang-up state. Generally, the software of the expander has certain fault-tolerant capability, and the influence of the expansion hang-up in a short time on the user service can be tolerated. Therefore, the CPLD can wait for one minute, and if the expander cannot repair the problem by itself, the heartbeat still does not exist, which indicates that the expander is hung up and cannot repair by itself. The CPLD can power down and re-power up the expander chip at the moment, and the expander powered up again can work normally.
S103: the BMC reads the CPLD register and judges whether a preset value exists in the CPLD register; if yes, entering S104;
in this step, the BMC needs to read the CPLD register and determine whether a preset value exists. Once present, expander chip hang-up is indicated. The read frequency of the BMC reading the CPLD register is not limited herein, and the CPLD register may be read in a predetermined cycle. The register state of the CPLD may be detected once for 1 second, for example.
S104: and erasing the CPLD register after the expander chip is powered on again.
Even if the CPLD powers off and powers on the expander chip again, the preset value still exists in the register of the CPLD, namely the register of the CPLD still shows the state that the expander is hung up, if the expander is hung up again at the moment, the BMC cannot judge whether the expander is hung up again, and cannot accurately record the log hung up. Therefore, after the BMC records the log, the register of the CPLD is erased and restored to the default value, so as to perform subsequent work.
In particular, the BMC may also generate alarm information and log.
The BMC accesses the CPLD register through the IIC, if the value of the register is not a preset value, the situation that the expander normally works and is not hung at the moment is indicated, the BMC does not perform any operation, and if the value of the register is found to be 0xA5, the situation that the expander is hung at the moment is indicated, on one hand, the BMC displays an alarm on a user interface, the alarm can be accurate to which expander, so that the problem is quickly positioned, meanwhile, the BMC records logs, and if the frequency of the BMC accessing the CPLD is short in high period, the hang time of the expander accurate to seconds can be recorded. The method can help research and development to quickly locate the reason for hanging death of the expander and carry out later improvement by combining the log recorded by the expander before hanging death.
It should be noted that there is no absolute sequential execution relationship between steps S103 and S104 and steps S101 and S102. In fact, the process of reading the CPLD register by the BMC is continuous, regardless of whether there is an expander chip hang-up condition. The method is used for ensuring that the CPLD register can be timely erased once the expander chip is hung dead, and avoiding influencing the judgment of next expander chip hanging dead. Usually, the BMC is also used for recording the system log, and once the preset value in the CPLD cannot be erased in time, the recording of the system log is affected.
According to the embodiment of the application, after the expander chip is detected to be hung dead, the CPLD is used for electrifying the expander chip again after a certain time, so that the expander chip can be automatically restarted, meanwhile, the CPLD generates the preset value in the CPLD register, the BMC can erase the CPLD register according to the preset value, the preset value detected each time is guaranteed to represent the real-time state of the current expander chip, and the repair efficiency after the expander chip is hung dead is improved.
The repair method provided by the present application is described below with CPLD and BMC, respectively.
For the CPLD, once the expander chip is hung up, the heartbeat signal cannot be sent, that is, only the high level or the low level continues, and the CPLD cannot receive the square wave signal, it is determined that the expander chip is hung up, and at this time, the preset value is written into the CPLD register. And meanwhile, timing is started when the expander chip is confirmed to be hung up, and the specific timing duration is within the fault-tolerant range. And after the timing is finished, the expander chip is powered on again so as to enable the expander chip to work normally.
For the BMC, when the expander chip is hung to death and cannot output a heartbeat signal, the CPLD writes a preset value into the CPLD register, and the BMC detects that the CPLD register has the preset value generated, namely, confirms that the expander chip is hung to death. After the CPLD timing is finished, the expander chip returns to normal. And after the BMC confirms that the expander chip is hung up, the preset value in the CPLD register needs to be cleared. Certainly, the BMC does not need to wait until the CPLD timing ends and then erase the CPLD register, that is, the CPLD timing is started can be regarded as being powered up again, and therefore, once the CPLD timing is started, the powering up again is an inevitable process. In addition, the BMC can record logs so that a person skilled in the art can confirm the reason for hanging up the expander chip and the like according to the logs. The BMC may also alarm to notify those skilled in the art that the expander chip is dead. When the frequency of hanging up the expander chip is higher, it is especially necessary to send out alarm information.
The following introduces a repair system for expander chip hang-up provided in the embodiments of the present application, and the repair system described below and the repair method for expander chip hang-up described above may be referred to correspondingly.
