In view of the above objects, a first aspect of the embodiments of the present invention proposes an embodiment of a method for updating SAS-Expander firmware based on IPMI commands. Fig. 1 is a schematic diagram illustrating an embodiment of a method for updating SAS-Expander firmware based on IPMI command according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, determining a SAS-Expander firmware upgrading mode in response to receiving an IPMI command for calling an SAS-Expander firmware upgrading tool;
s2, opening and reading data of the SAS-Expander firmware through the SAS-Expander firmware upgrading tool;

IPMI (Intelligent Platform Management Interface) is based on Management
An industrial standard adopted by peripheral equipment used in an enterprise system with a structure is that a user can monitor physical health characteristics of a server, such as temperature, voltage, fan working state, power state and the like, by using IPMI, and can perform read-write operation on equipment on an I2C bus on a mainboard by sending an IPMI command.
In some embodiments, further comprising: in response to receiving an IPMI command for SAS-Expander firmware upgrade, device access on the I2C bus on which the SAS-Expander resides is stopped. Because many other devices are accessed by the BMC on the I2C bus where the SAS-Expander is located, an IPMI command for preparing an I2C channel before responding to the SAS-Expander firmware upgrade needs to be developed in the BMC, after the BMC receives the SAS-Expander firmware upgrade preparation command, the BMC stops accessing the devices on the I2C bus where the SAS-Expander is located, and the I2C bus access control right is given to the SAS-Expander firmware upgrade for use.
In response to receiving an IPMI command that invokes the SAS-Expander firmware upgrade tool, a mode of SAS-Expander firmware upgrade is determined. The embodiment of the invention supports two upgrading modes of in-band and out-of-band, judges the mode for upgrading the SAS-Expander firmware according to the command input when the SAS-Expander firmware upgrading tool is called under the Linux system, and judges whether the upgrading command is correct and effective according to the input parameter. If the upgrading command is invalid or wrong, saving the input command into a local log file, wherein the local log file can be, for example, expander _ update.log, stopping the upgrading process and returning an error code; if the upgrading command is valid and correct, the SAS-Expander firmware upgrading process can be started.
The SAS-Expander firmware upgrade tool opens and reads data of the SAS-Expander firmware. The SAS-Expander firmware upgrading tool opens and reads the SAS-Expander firmware file, if the opening fails, information returned by the failure is stored in a local log file Expander _ update.
And applying for a memory space based on the mode, and loading the data to the memory space. And loading the firmware file data into the memory space applied by the upgrading tool for upgrading data packaging. After the firmware file is successfully loaded to the memory space applied by the SAS-Expander firmware upgrading tool, packaging data in the memory space according to an SAS-Expander firmware upgrading protocol, then sending an upgrading state query command to the SAS-Expander to query whether the current state of the SAS-Expander is idle or upgrading, exiting if the current state of the SAS-Expander is upgrading, entering an upgrading mode if the current state of the SAS-Expander is idle, and recording the description of the event starting to be upgraded and the starting time into a local log file Expander _ update.
And upgrading and packaging the data in the memory space, and sending the data package to SAS-Expander firmware for upgrading. And after the upgrading tool executes an upgrading mode, sending a data packet to the SAS-Expander according to a format specified by an upgrading protocol, reading out the current upgrading state and progress, storing the returned state into a local log file Expander-update log file, and printing and outputting the current upgrading progress to a screen for a server operation and maintenance worker to observe the current upgrading progress and condition. If an upgrade error occurs to cause upgrade failure, recording an upgrade state returned when the upgrade fails so as to analyze the reason of the upgrade failure, then exiting the current upgrade process, and restarting to attempt to upgrade the firmware, wherein an attempt threshold value can be set, for example, 5 times, if 5 times of failures are all failures, the operation of the whole upgrade firmware is exited, an error code returned when the failures are recorded, and if no error exists, the subsequent upgrade process is continued.
In some embodiments, further comprising: and responding to the completion of the data packet transmission, and controlling the writing end mark word of the I2C bus where the SAS-Expander firmware is located by the SAS-Expander firmware upgrading tool through an IPMI command. When the firmware upgrading process is executed to the end stage, the SAS-Expander firmware upgrading tool writes an end mark word through an IPMI command operation I2C bus, and reads the end state of the SAS-Expander firmware upgrading.
In some embodiments, further comprising: judging whether to return a correct ending mark word; and in response to not returning the correct end marker word, rewriting the end marker word and judging whether to return the correct end marker word again. If the correct end marker word is returned, the upgrade is successful, the description of the upgrade successful event is recorded and saved in the local log file, if the return is failed, the upgrade end marker word is retried to be written, the end state is read,
in some embodiments, further comprising: judging whether the frequency of not returning the correct end marker word reaches a threshold value; and in response to the number of times that the correct end marker word is not returned reaching a threshold value, exiting the SAS-Expander firmware upgrading process and recording the returned error code. A threshold value, for example 5, may be set, and if 5 times are failures, the whole operation of upgrading the firmware is exited, and the error code returned when the failures occur is recorded. If no error exists, the SAS-Expander is subjected to the final reset operation after the specified delay, the upgraded firmware is enabled to take effect, and the event description successfully upgraded is stored in a local log file for operation and maintenance personnel to check.
The embodiment of the invention provides an IPMI command-based SAS-Expander upgrading method independent of BMC, which can be widely applied to SAS-Expander firmware upgrading of a server, has the functions of recording key information in an upgrading process and storing log files, meets the requirements of batch and networking operation of server operation and maintenance personnel when upgrading SAS-Expander firmware, can quickly and effectively find problems and locate the problems, increases the accuracy of fault diagnosis of a server management system, and is convenient for the operation and maintenance personnel to upgrade management and fault location of the SAS-Expander firmware of the server.
