Wherein the VPD information includes product information (e.g., product sn, etc.) and hardware configuration information (e.g., CPU model, rate, and which types of interface cards are supported by each slot, etc.).
The CMC performing VPD information access on the same storage product includes a main CMC0 and a spare CMC1, and in the access process, if one CMC (the main CMC0 or the slave CMC1) fails, the main CMC0 and the spare CMC1 need to be switched.

Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1, a method for accessing stored VPD information according to the present invention includes the following steps:
s1, detecting whether the IP addresses of the CMC are communicated;
s2, calling an ipmitool command to access the stored VPD information to the CMC communicated with the IP address;
and S3, recording the access process and the result of the CMC.
In the above steps S1 to S3, the master-slave relationship of the CMC is no longer concerned, and the ipmitool command can be called to the CMC as long as the CMC is connected through the IP to access the VPD information, thereby avoiding the abnormal situation occurring in the master-slave switching process of the CMC and improving the success rate of accessing the VPD information.
Wherein in step S1, it is detected whether the IP addresses of the CMCs are connected by using Ping pass test. The specific method of the Ping communication test is to send data request packets to the CMC, check whether the number of the data request packets received by the CMC end is consistent with the number of the data request packets sent, if so, indicate that the IP address of the CMC is connected, otherwise, the IP address of the CMC is not connected.
The VPD information stored in step S2 is stored in a midplane EEPROM (Electrically erasable programmable Read-Only Memory, which is a Memory chip that does not lose data after power failure) and/or a Memory controller EEPROM. When needing a plurality of storage controllers to share VPD information, storing the VPD information on a middle plate EEPROM; when the VPD information is required to be shared by a single storage controller, the VPD information is stored in the storage controller EEPROM. For example, for the dual-control storage device, the dual-control storage device comprises storage controllers nodeA and nodeB, when two storage controllers are required to share VPD information, the VPD information is stored in the midplane EEPROM, and when a single storage controller is required to share VPD information alone, the VPD information is stored in the storage controllers EEPROM, namely, the nodeA EEPROM and the nodeB EEPROM respectively. The method is also suitable for four-control storage equipment and multi-control storage equipment, and the difference is only in the number of the arranged controller EEPROMs, and the number of the arranged storage controller EEPROMs is the same as that of the controllers of the storage equipment.
As shown in fig. 2, the specific step of calling ipmitool command to access the stored VPD information for the CMC with connected IP address in step S2 is:
s21, calling an ipmitool command;
s22, judging whether the access of the CMC is successful;
s23, if the CMC access is successful, no operation is carried out;
s24, if the CMC fails to be accessed, judging whether the CMC has errors in a past period of time;
s25, if the CMC has errors in a period of time, calling an ipmitool command again to make the CMC access the stored VPD information;
and S26, if the CMC has not error in the past period, calling the ipmitool command for many times to make the CMC access the stored VPD information.
The reason why no operation is performed in step S23 is that, when the CMC access is successful, the stored VPD information can be directly acquired, and the process proceeds to step S3.
The elapsed time in steps S24 to S26 is set to 30 seconds, and the number of times the ipmitool command is called multiple times in step S26 is set to 10 times.
In the above steps S21 to S26, in order to solve the problem that the CMC has connected IP in the prior art but fails during the execution of the command, a retry mechanism is added, the CMC error is analyzed and determined, an appropriate number of retries is set, and the success rate of the CMC accessing the VPD information is further increased while ensuring that the VPD information is not overtime.
And step S3, recording the access process and the result of the CMC, and generating a log record file, so as to facilitate the subsequent analysis and check of the access process of the CMC.
As shown in fig. 3, the present invention further provides a stored VPD information access system, which includes a connectivity test unit 1, a VPD information access unit 2, and a storage unit 3, which are connected in sequence; the communication testing unit 1 is used for detecting whether the IP addresses of the CMCs are communicated or not, the VPD information access unit 2 is used for calling an ipmitool command to access the stored VPD information for the CMCs with communicated IP addresses, and the storage unit 3 is used for recording the access process and results of the CMCs.
The VPD information access unit 2 comprises a command calling module 21, an access judging module 22 and an error judging module 23, wherein the input end of the command calling module 21 is respectively connected with the output end of the communication testing unit 1 and the output end of the error judging module 23, the input end of the access judging module 22 is connected with the output end of the command calling module 21, and the output end of the access judging module 22 is respectively connected with the input end of the storage unit 3 and the input end of the error judging module; the command calling module 21 is configured to call an ipmitool command, the access determining module 22 is configured to determine whether the CMC is successfully accessed, and the error determining module 23 is configured to determine whether an error occurs in the CMC.
The access judging module 22 judges whether the CMC is successfully accessed, if the CMC is successfully accessed to the VPD information, the access result of the CMC is directly output to the storage unit 3, if the CMC is unsuccessfully accessed to the VPD information, a signal is output to the error judging module 23, the error judging module 23 judges whether the CMC has an error in a past period of time, if the CMC has an error in a past period of time, the error judging module 23 outputs a signal to the command calling module 21, and then calls an ipmitool command once again to enable the CMC to access the stored VPD information, and if the CMC is not successfully accessed, the CMC finishes accessing, and outputs the access result to the storage unit 3, and if the CMC has a past period of time and no error, the ipmitool command is called for multiple times to enable the CMC to access the stored VPD information. The number of times in which the ipmitool command is called is set to 10 times, and the procedure and the access result are output to the storage unit 3.
The foregoing is only a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the invention, and such modifications and improvements are also considered to be within the scope of the invention.
