Background technique

Unlike the hard disk and the host operating system that have a large space to store their internal hard disk logs and system logs, the SAS card (disk array card) is a PCIE card. Due to the limitations of the embedded system and hardware design, the internal storage of logs The space is very small. At present, the SAS card uses the internal buffer of the card to record the firmware operation log, and the buffer space is very small, generally only at the level of KB to more than a dozen KB.

Therefore, at present, the internal buffer of the SAS card adopts the method of circularly recording the firmware log. After the buffer log is full, the log when the fault occurs will be overwritten soon because the log storage space is too small.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention discloses a method for collecting SAS card firmware logs, as shown in Fig. 1, the method includes:

S11: Send a memory application request to the host, and obtain a host memory circular buffer in the memory of the host.

Specifically, after the SAS card is powered on, it can automatically send a memory application request to the host, so that the host can use the memory application request to divide the storage space from the memory, which is greater than or equal to the circular buffer, and is used to store the memory space of the SAS card firmware log The host memory circular buffer.

Specifically, apply for a certain amount of memory space in advance to the memory of the host for storing SAS card firmware logs. In order to prevent the SAS card firmware logs in the circular buffer from being overwritten, it is necessary to transfer all the SAS card firmware logs in the circular buffer to It is stored in the host memory circular buffer. Therefore, the storage space of the host memory circular buffer cannot be smaller than the space of the circular buffer. The storage space of the zone is much larger than the space size of the circular buffer. For example, the space size of the circular buffer can be 12KB, and the storage space of the host memory circular buffer can be 12MB, which is 1024 times the space size of the circular buffer. To ensure that there is enough space in the host memory circular buffer to store the SAS card firmware log.

Among them, the size of the requested host memory circular buffer can correspond to the SAS card firmware log that may be generated during the operation of the SAS card, that is, ensure that the size of the SAS card firmware log generated during the operation of the SAS card does not exceed the storage space of the host memory circular buffer , so as to ensure that all SAS card firmware logs generated during the operation of the SAS card can be retained.

S12: Generate and store the SAS card firmware log of the SAS card to a local circular buffer.

Specifically, a SAS card firmware log of the SAS card is generated according to the running information of the SAS card, and the SAS card firmware log is stored locally, that is, in a circular buffer of the SAS card.

S13: Determine whether the remaining storage space of the circular buffer satisfies a preset first storage threshold.

Specifically, in order to be able to perform corresponding actions after the circular buffer is full of SAS card firmware logs, and to prevent the SAS card firmware logs from being quickly overwritten, it is determined whether the remaining storage space of the circular buffer meets the preset first storage threshold, for example, Judging whether the remaining storage space of the circular buffer is less than 10%, or whether the remaining storage space of the circular buffer is 0, that is, whether the circular buffer has been completely filled with the SAS card firmware log.

S14: If yes, all the SAS card firmware logs in the circular buffer are transferred to the host memory circular buffer of the host for storage.

Specifically, after the remaining storage space of the circular buffer meets the preset first storage threshold, all the SAS card firmware logs in the circular buffer can be transferred to the host memory circular buffer of the host for storage to avoid loss of logs. For example, if the preset first storage threshold is 10% of the remaining storage space, all the SAS card firmware logs that occupy 90% of the storage space in the circular buffer are transferred to the host memory circular buffer of the host for storage to avoid The remaining space in the circular buffer is insufficient, causing the SAS card firmware log to be overwritten quickly, leaving enough time for extracting the SAS card firmware log.

It can be understood that since the writing process of the SAS card firmware log is continuous, the SAS card firmware log in the transferred host memory circular buffer is the SAS card firmware log in the current circular buffer at the moment when the first storage threshold is judged to be satisfied. Card firmware log, when transferring the SAS card firmware log, the circular buffer will clear the content of the transferred SAS card firmware log, and transfer the SAS card firmware log to the host memory circular buffer in a form similar to cutting. DMA technology (DMA, Direct Memory Access, direct memory access) transfers the SAS card firmware log to the host memory circular buffer.

It should be noted that the SAS card firmware log is stored in the memory of the host, therefore, the user can directly obtain the SAS card firmware log in the memory through the host, instead of using the serial port debugging technology to directly connect to the SAS card to obtain the SAS card firmware Logs, log acquisition is more convenient.

S15: If not, continue to generate and store the SAS card firmware log of the SAS card to the circular buffer.

Specifically, before the remaining storage space of the circular buffer meets the first storage threshold, S12 and S13 can be continued to store the SAS card firmware log in the circular buffer until the remaining storage space of the circular buffer meets the first storage threshold.

It should be noted that the generation speed of the SAS card firmware log of the SAS card is very fast. Among them, the writing speed of the SAS card writing data into its own circular buffer is the fastest, followed by the writing speed of the SAS card writing data into the host memory circular buffer , so in order to avoid data loss caused by new data overwriting the remaining unwritten data before the data writing is completed, the SAS card first writes the data to its own circular buffer, and then uses the first storage threshold to cycle The SAS card firmware log in the buffer is stored in the host memory circular buffer, which ensures that data will not be lost due to the writing speed.

It can be understood that the host may be a user terminal connected to the SAS card, for example, a computer.

It can be seen that, on the basis of the original circular buffer of the SAS card, the embodiment of the present invention applies to the host memory for storing the redundant SAS card firmware log for the host memory circular buffer. When the remaining space in the circular buffer is insufficient, the After the first storage threshold, all the SAS card firmware logs in the circular buffer are transferred to the host memory circular buffer. There is enough storage space in the host memory circular buffer to store the SAS card firmware logs during the operation of the SAS card, avoiding SAS When the SAS card firmware log is quickly lost when the card fails, the SAS card firmware log can be saved for a long time, and at the same time, sufficient acquisition time is left for the user to obtain the SAS card firmware log. In addition, the user can directly obtain the SAS card from the memory through the host Card firmware logs instead of getting SAS card firmware logs through serial port debugging, which is more convenient, improves the maintenance efficiency of SAS cards, and indirectly improves the reliability of SAS cards.

Further, the process of transferring all the SAS card firmware logs in the circular buffer to the storage in the host memory circular buffer of the host in the above S14 can be specifically as that when the host memory circular buffer is full of SAS card firmware logs, the circular All the SAS card firmware logs in the buffer are transferred to the host memory circular buffer, and the latest SAS card firmware log is overwritten for storage.

Specifically, if the storage space of the host memory circular buffer is still insufficient, then the latest SAS card firmware log can only be overwritten with the latest SAS card firmware log for storage, because the host memory circular buffer is large enough and The working time of the SAS card is the vast majority, so even if it is overwritten, the SAS card firmware log during the SAS card failure will not be overwritten.

Specifically, in order to avoid the situation that the SAS card firmware log has not been completely transferred, the newly generated SAS card firmware log will cover the incompletely transferred SAS card firmware log and cause the SAS card firmware log to be lost. The speed is fast enough. Due to the introduction of a large enough host memory circular buffer, there is enough time for data transfer before the host memory circular buffer is full. Therefore, when the remaining space of the host memory circular buffer meets the second storage threshold , transfer all the SAS card firmware logs in the host memory circular buffer to the host hard disk for storage.

Specifically, on the basis of memory, the SAS card firmware log can also be stored in a hard disk with larger storage space, and the second storage threshold can be set as when the remaining space of the host memory circular buffer is less than 50%. At this time, The time required to fill the storage space of the remaining host memory circular buffer is much longer than the time required to write the SAS card firmware log in the host memory circular buffer to the hard disk.

Wherein, the setting of the second storage threshold can be determined according to the time when the log is written to the hard disk, as long as the remaining storage space can ensure that the SAS card firmware log has been written to the hard disk before the host memory circular buffer is full.

Specifically, the above-mentioned host memory circular buffer can specifically be that the storage space is greater than or equal to the circular buffer, and the continuous memory area is used to store the memory space of the SAS card firmware log. The continuous memory space is convenient for data storage and management, and can improve log management efficiency. .

Specifically, the process of sending the memory application request to the host in the above S11 to obtain the host memory circular buffer in the memory of the host may specifically be sending a memory space application request and a memory lock request to the host, so that the host uses the memory space application request from The host memory circular buffer is divided in the memory to obtain the host memory circular buffer, so that the host uses a memory lock request to lock the host memory circular buffer.

Specifically, while applying for memory space, a memory lock request is also sent to the host, so that the host locks the host memory circular buffer for use only by the SAS card sending the request, thereby avoiding memory usage conflicts.

Correspondingly, the embodiment of the present invention also discloses a SAS card firmware log collection system, as shown in Figure 2, the system includes:

The request sending module 11 is used to send a memory application request to the host to obtain the host memory circular buffer in the memory of the host;

Wherein, the host memory circular buffer is a memory space whose storage space is greater than or equal to the circular buffer, and is used for storing SAS card firmware logs.

It can be seen that, on the basis of the original circular buffer of the SAS card, the embodiment of the present invention applies to the host memory for storing the redundant SAS card firmware log for the host memory circular buffer. When the remaining space in the circular buffer is insufficient, the After the first storage threshold, all the SAS card firmware logs in the circular buffer are transferred to the host memory circular buffer. There is enough storage space in the host memory circular buffer to store the SAS card firmware logs during the operation of the SAS card, avoiding SAS When the SAS card firmware log is quickly lost when the card fails, the SAS card firmware log can be saved for a long time, and at the same time, sufficient acquisition time is left for the user to obtain the SAS card firmware log. In addition, the user can directly obtain the SAS card from the memory through the host Card firmware logs instead of getting SAS card firmware logs through serial port debugging, which is more convenient, improves the maintenance efficiency of SAS cards, and indirectly improves the reliability of SAS cards.

Specifically, a repetition judging module 15 may also be included; wherein,

The repeat judging module 15 is used to continue calling the log generating module 12 to generate and store the SAS card firmware log of the SAS card to the circular buffer if the storage space judging module 13 judges that the remaining storage space does not meet the first storage threshold.

Specifically, the above-mentioned log transfer module 14 can be specifically used for if the storage space judging module 13 judges that the remaining storage space meets the first storage threshold, then when the host memory circular buffer is full of SAS card firmware logs, the All SAS card firmware logs are transferred to the host memory circular buffer, and the latest SAS card firmware log is overwritten for storage.

Specifically, it may also include a hard disk storage module; wherein,

The hard disk storage module is configured to transfer all SAS card firmware logs in the host memory circular buffer to the host hard disk for storage when the remaining space of the host memory circular buffer satisfies the second storage threshold.
