Detailed Description
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 only a part of the embodiments of the present application, and not all of the 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.
Currently, when processing data transmitted between a server and a hard disk, the storage system can be used for processing the corresponding data with high reliability and high speed. Because a Central Processing Unit (CPU) of the storage system processes the service data, a pci (personal component interconnect express) interface is provided outside the CPU; while the hard disk of the storage system is commonly used by SAS (Serial Attached SCSI) interface, there is a case where pci is converted into an SAS interface and is interfaced to each hard disk by SAS expander. In the storage system, when the device is managed, an EM (enclosure management) thread in a host system and an SES program running on the SAS expander, that is, a management and control system running on the SAS expander need to be used, for example, the SES program reads a peripheral state of the device and transmits abnormal state information to the EM thread, and the EM thread responds to and processes the abnormal state information.
The management and control system is a program running on the SAS expander, the main service of the expander is to expand an SAS link, and a few SAS ports are used as uplink ports to be expanded into multiple downlink ports, so that the connection of a plurality of hard disks is realized; the service of connecting the hard disk is the main service, and then a plurality of i2c links are expanded to realize the function of management and control. The tasks of the governing system may be as follows: the peripheral states of the equipment, such as information of a fan, voltage, the fan and the like, are read in a high-frequency circulation mode, abnormal judgment is carried out, and when the abnormal state is judged to occur, the state and the information are reported to the EM thread; receiving and executing a control instruction sent by an EM thread; and performing self-control treatment inside the cabinet, for example, automatically adjusting the rotating speed of the fan according to a fan rotating speed strategy when the temperature of the cabinet is detected. EM threads, as part of the storage host system, tasks may be as follows: receiving data and state sent by the SES program, and updating internal data; when an abnormal state exists, an alarm which can be visually checked by a user is initiated, and the main system is informed whether other processing is required for the abnormality or not, for example, whether shutdown protection is required or not when the temperature of some key elements is ultrahigh; when the main system controls certain hardware in the process of program operation, the hardware is issued to the SES program through the EM thread, and the SES program actually controls the hardware, such as reading and writing VPD configuration information, turning off a certain abnormal control lamp and the like.
In this process, it may be necessary to debug the data exception occurring on the SAS link, however, for example, as the device operates, the reason for the data exception may be as follows: a single read failure of the semiconductor chip; the access conflict in the software is read abnormally, and the retry is normal; reading failure of a single element, and recovering to be normal after a repair strategy; a single element fails to read, but the repair strategy cannot repair, and the reading fails continuously; when a certain link is abnormal, all data hung on the link are abnormal in reading, and the data comprise repairable data and irreparable data; the read register detects that a certain abnormality occurs; the link between the multi-control cascade SES programs is abnormal, and the communication is abnormal; single-transfer exceptions and irreparable exceptions. The SAS link cannot be debugged effectively if it is debugged only by the collected data. The SAS link debugging method provided by the application can effectively debug the SAS link.
Referring to fig. 1, fig. 1 is a first flowchart of a SAS link debugging method according to an embodiment of the present disclosure.
The SAS link debugging method provided in the embodiment of the present application, applied to a host system, may include the following steps:
step S101: receiving dump data transmitted by a management and control system; the dump data is data obtained after the management and control system collects the memory data according to the target variable address and the target variable size.
In practical application, the management and control system may collect the memory data according to the target variable address and the target variable size to obtain corresponding dump (backup file system) data, that is, the dump data may reflect the situation of the memory data in the SAS link operation process, and then transmit the dump data to the main system; correspondingly, the main system needs to receive dump data transmitted by the management and control system.
In practical application, the main system and the management and control system may establish a dump interaction channel between the main system and the management and control system by a newly-built SEND/RECEIVE diagnostic page based on an SES protocol of an SAS interface, so that the main system and the management and control system transmit dump data and the like.
It should be noted that, because the management and control system generally does not have the processing capability of the dump data, but the management and control system may have the collection capability of the dump data, and the main system generally has the processing capability of the dump data, when the SAS link is debugged by the dump in the storage system, the management and control system may be given the collection capability of the dump data, and the main system may be given the processing capability of the dump data, so as to debug the SAS link by the dump; the management and control system copies the memory data without occupying extra memory, so that the service pressure of the management and control system can be reduced; with the increase of the functional modules to be debugged, only the target variable addresses and the target variable sizes need to be updated, and a huge code amount does not need to be additionally increased, so that the debugging function is simple and is convenient to implement.
Step S102: and saving the dump data as a dump file.
In practical applications, after receiving the dump data, the host system may save the dump data as a dump file, for example, save the dump data as a dump file by using a dump file generation tool under the Linux system, so as to debug the SAS link by using the dump file.
Step S103: and analyzing the dump file to obtain an analysis result.
In practical application, after the main system saves the dump data as the dump file, the main system can analyze the dump file to obtain an analysis result, so as to debug the SAS link in batches.
In a specific application scenario, the main system may analyze the dump file online to obtain an analysis result, may analyze the dump file offline to obtain an analysis result, and the like, which is not specifically limited herein.
Step S104: displaying the analysis result according to the variable name defined by the display data structure body and the display form of the data, and debugging based on the analysis result; the main system is a master control system of a storage system where the SAS link is located; the control system is a control system in the SAS expander.
In practical application, after the main system analyzes the dump file to obtain an analysis result, the main system can display the analysis result according to a variable name defined by the display data structure and a display form of data, so that a user and the like can know the analysis result, and the user can further know the debugging process of the SAS link according to the analysis result.
The SAS link debugging method is applied to a main system and used for receiving dump data transmitted by a management and control system; saving the dump data as a dump file; analyzing the dump file to obtain an analysis result; displaying the analysis result according to the variable name defined by the display data structure body and the display form of the data, and debugging based on the analysis result; the main system is a master control system of a storage system where the SAS link is located; the control system is a control system in the SAS expander; the dump data is data obtained after the management and control system collects the memory data according to the target variable address and the target variable size. In this application, the management and control system can transmit the dump data that the memory data corresponds to main system, and the main system can handle the dump data through the dump file, and then debugs the SAS link with the help of the dump, because the dump is convenient for record information, so can effectively debug the SAS link.
According to the SAS link debugging method provided by the embodiment of the application, before the main system receives dump data transmitted by the management and control system, the main system can also register the data to the management and control system and store the target variable address and the target variable size into the dump linked list of the management and control system, so that the management and control system stores the target variable address and the target variable size based on the dump linked list.
That is, the main system may store the target variable address and the target variable size of the memory data that the main system needs to view in the management and control system in advance by means of data registration with the management and control system, so that the management and control system may directly collect the memory data according to the target variable address and the target variable size.
It should be noted that, in this embodiment, the management and control system stores the target variable address and the target variable size by using the dump linked list, and in practical application, the management and control system may also store the target variable address and the target variable size in other manners, which is not specifically limited herein.
In the SAS link debugging method provided by the embodiment of the present application, in the process that the main system parses the dump file to obtain a parsing result, in order to obtain the parsing result, the dump file may be patterned based on a preset Linux script to obtain a patterned result; analyzing the graphical result and the symbol table file together based on a preset symbol table analyzing tool to obtain an analysis result; the symbol table file is a file generated when the management and control system compiles.
In practical application, the main system can be used for imaging the dump file based on a Linux script such as tcl/tk or python and the like to obtain an imaging result and the like.
In the SAS link debugging method provided in the embodiment of the present application, in the process of displaying the analysis result, the host system may display the analysis result in a menu format according to the variable name defined by the display data structure and the display format of the data in order to facilitate a user to view the analysis result.
In a specific application scenario, in order to facilitate a user to view required data information, after the main system displays an analysis result in a menu mode, a viewing instruction can be received, wherein the viewing instruction comprises an instruction generated after a key of the main system is triggered; and operating the menu according to the viewing instruction, and displaying a corresponding analysis result.
For example, the main system may select a corresponding structure variable name in the menu to display when the user triggers the up-down key; under the condition that a user triggers an Enter key, entering a next-level menu, expanding and displaying the next-level data definition, and at the moment, when the menu content with the structural body is selected, still expanding through the Enter; when the user triggers the Esc key, the user can enter the upper level menu; under the condition that the user inputs the g key, a function of quickly searching on the page can be started for the user; under the condition that a user triggers the r key, the value can be read again, and reading of a certain variable is initiated to the management and control system once, and the like; and under the condition that the user triggers the f key, automatically establishing detection transmission of a certain variable with the control system, sending the variable after the control system detects the change, analyzing and displaying the variable after the main system receives the variable, and the like.
In the SAS link debugging method provided in the embodiment of the present application, before receiving dump data transmitted by a management and control system, a main system may further send a dump data reading instruction to the management and control system, so that the management and control system reads the dump data; the type of the dump data reading instruction comprises a full-volume dump data reading instruction and a single-variable dump data reading instruction.
That is, in the present application, the main system may control the management and control system to collect all the memory data at one time, or may control the management and control system to collect only one memory data at one time, and the present application is not limited specifically herein.
In a specific application scenario, in order to send a dump data reading instruction, a corresponding data reading instruction flag bit may be set in the management and control system, so that the main system may send the corresponding dump data reading instruction to the management and control system only by triggering the corresponding data reading instruction flag bit.
