[0011] The embodiments will be described in detail below with reference to the drawings. <Embodiment> A maintenance system 1 (an example of a processing system) according to one embodiment of this disclosure will be described with reference to the drawings. The maintenance system 1 is a system that can improve convenience.

[0012] (Configuration of the maintenance system) A maintenance system 1 according to one embodiment of the present disclosure will be described with reference to the drawings. Figure 1 is a diagram showing an example of the configuration of a maintenance system 1 according to several embodiments of the present disclosure. As shown in Figure 1, the maintenance system 1 includes a maintenance terminal 10 and a storage device 20.

[0013] As shown in FIG. 1, the maintenance terminal 10 includes a memory dump collection request means 101, a previous memory dump presence / absence information 102, a memory dump synthesis function 103, and a memory dump storage area 104.

[0014] The storage device 20 includes a memory dump collection function 201, a memory dump update management function 202, a memory dump update management table 203, and a memory dump storage area 204. The memory dump collection function 201 includes a memory dump update area extraction function 2011.

[0015] The maintenance terminal 10 and the storage device 20 are connected by a network. The memory dump received from the storage device 20 by the maintenance terminal 10 through the network is written into the memory dump storage area 104. That is, the memory dump storage area 104 receives the memory dump of the storage device 20. Thus, the memory dump storage area 204 stores the memory dump of the storage device 20. The memory dump of the storage device 20 is log information that holds the information of the storage device 20 itself, with the area separated for each piece of information and without time information. For example, examples of the log information in the memory dump include information indicating the state of the disk drive, information indicating the state of the controller, information indicating the set value set for a certain function, statistical information, information indicating program variables, and the like. The memory dump collection request means 101 of the maintenance terminal 10 can request the memory dump collection function 201 of the storage device 20 to collect a memory dump. The memory dump collection function 201 of the storage device 20 can transfer the memory dump stored in the memory dump storage area 204 to the memory dump synthesis function 103 of the maintenance terminal 10.

[0016] The memory dump update management table 203 includes the information 2031 of the storage device 20 and a memory dump update flag 2032. FIG. 2 is a diagram showing an example of the information 2031 of the storage device 20 and the memory dump update flag 2032 according to some embodiments of the present disclosure.

[0017] The information 2031 of the storage device 20 is memory dump information including various information in the storage device 20 such as the status of each disk drive, the status of each controller, the set values of each function, statistical information, and program variables. When the value of the memory dump update flag 2032 is 1, it indicates that the information 2031 of the storage device 20 has been updated. Also, when the value of the memory dump update flag 2032 is 0, it indicates that there has been no update to the information 2031 of the storage device 20. That is, 0 is set as the initial value of the memory dump update flag 2032 for the target information in the memory dump update management table 203. When there is an update to the information 2031 of the storage device 20, the memory dump update management function 202 sets the memory dump update flag 2032 for the target information in the memory dump update management table 203 to 1. For example, when the disk drive 02 installed in the storage device 20 fails, the memory dump update flag for the status of the disk drive 02 among the information 2031 of the storage device 20 in the memory dump update management table 203 is set to 1. In the present disclosure, the information 2031 of the storage device 20 that is the target for confirming the presence or absence of an update is information in the program area that can be used by the user, and information in areas such as the register space and the OS area that cannot be updated by the user is excluded from the target. Details of the processes performed by the maintenance terminal 10 and the storage device 20 will be described later.

[0018] Note that the processes performed by the maintenance system 1 according to an embodiment of the present disclosure are not limited to the above-described processes. For example, the maintenance system 1 may perform the processes described below.

[0019] (Processes performed by the maintenance system) FIG. 3 is a diagram showing an example of the processing flow of the maintenance system 1 according to an embodiment of the present disclosure. Next, the processes performed by the maintenance system 1 will be described with reference to FIG. 3. Note that when there is an update to the information 2031 of the storage device 20, it is assumed that the memory dump update management function 202 has set the memory dump update flag 2032 for the target information in the memory dump update management table 203 to 1.

[0020] When the maintenance terminal 10 requests the storage device 20 to collect a memory dump, the memory dump collection request means 101 checks the previous memory dump existence information 102 to determine whether or not the previous memory dump exists in the memory dump storage area 104 (step S1). If the memory dump collection request means 101 determines that the previous memory dump does not exist in the memory dump storage area 104 (NO in step S1), it collects the entire memory dump from the memory dump storage area 204 of the storage device 20. Specifically, the memory dump collection request means 101 sends a request to collect the entire memory dump to the memory dump collection function 201 (step S2). The memory dump collection function 201 receives the request to collect the entire memory dump from the memory dump collection request means 101. When the memory dump collection function 201 receives the request to collect the entire memory dump, it collects the entire memory dump in the memory dump storage area 204 (step S3). The memory dump acquisition function 201 transmits the entire acquired memory dump to the memory dump acquisition request means 101 (step S4). The memory dump acquisition request means 101 acquires the entire memory dump in the memory dump storage area 104 (step S5).

[0021] Furthermore, if the memory dump acquisition request means 101 determines that there was a previous memory dump based on the previous memory dump existence information 102 (YES in step S1), it sends a request to the memory dump acquisition function 201 to acquire the memory dump update area (an example of log information within the updated section), which is the updated area of ​​the memory dump (step S6).

[0022] The memory dump acquisition function 201 receives a request to acquire a memory dump update area from the memory dump acquisition request means 101. When the memory dump acquisition function 201 receives a request to acquire a memory dump update area, the memory dump update management function 202 extracts the target information for which the memory dump update flag is set to 1 in the memory dump update management table 203 (step S7). The memory dump update management function 202 instructs the memory dump acquisition function 201 to extract the memory dump of the target information (step S8). Then, the memory dump update management function 202 sets the memory dump update flag of the target information in the memory dump update management table 203 to 0 (step S9). Next, the memory dump acquisition function 201 uses the memory dump update area extraction function 2011 to extract the memory dump update area, which is the updated area of ​​the memory dump of the target information (step S10). The memory dump acquisition function 201 transmits the extracted memory dump update area, along with its target information, to the memory dump acquisition request means 101 (step S11). The memory dump acquisition request means 101 instructs the memory dump synthesis function 103 to synthesize the previous memory dump with the received memory dump update area. The memory dump synthesis function 103 synthesizes the previous memory dump with the received memory dump update area in accordance with the instruction (step S12). As a result, the maintenance terminal 10 obtains a complete memory dump.

[0023] (advantage) The above describes a maintenance system 1 according to one embodiment of the present disclosure. Maintenance system 1 (an example of a processing system) is a maintenance system comprising a storage device 20 and a maintenance terminal 10. The storage device 20 includes a memory dump update management function 202 (an example of a management means) that manages whether or not there are updates for each log information of the storage device 20 divided into storage areas, and a memory dump acquisition function 201 (an example of a transmission means) that transmits only the log information of the storage device 20 within the updated area to the maintenance terminal 10. The maintenance terminal 10 includes a memory dump synthesis function 103 (an example of a synthesis means) that synthesizes the log information of the storage device 20 received from the storage device 20 with the memory dump it holds.

[0024] This maintenance system 1 allows the storage device 20 to send only the updated log information from the memory dump to the maintenance terminal 10. The maintenance terminal 10 then combines the log information received from the storage device 20 with the memory dump it holds. In other words, the storage device 20 sends less log information than the total log information to the maintenance terminal 10, and the maintenance terminal 10 can obtain information equivalent to all the log information by combining the log information with the memory dump it holds. As a result, the maintenance system 1 can be made more convenient.

[0025] <First modified example of the embodiment> (Configuration of the maintenance system) A maintenance system 1 according to a first modification of one embodiment of the present disclosure will now be described. In one embodiment of the present disclosure, it was described that one maintenance terminal 10 is connected to the storage device 20. However, in the first modification of one embodiment of the present disclosure, multiple maintenance terminals 10a, 10b, 10c, ... may be connected to the storage device 20. Note that the maintenance terminals 10a, 10b, 10c, ... may be collectively referred to as maintenance terminal 10. When multiple maintenance terminals 10 are connected to the storage device 20, each maintenance terminal 10 transmits information to the storage device 20 that identifies itself as a maintenance terminal 10.

[0026] Figure 4 shows an example of a first table included in the memory update information management table 203 according to a first modification of one embodiment of the present disclosure. Figure 5 shows an example of a second table included in the memory update information management table 203 according to a first modification of one embodiment of the present disclosure. Figure 6 shows an example of a third table included in the memory update information management table 203 according to a first modification of one embodiment of the present disclosure. For example, Figure 4 is a first table showing information 2031a and a memory dump update flag 2032a for the storage device 20. Also, for example, Figure 5 is a second table showing information 2031b and a memory dump update flag 2032b for the storage device 20. Also, for example, Figure 6 is a third table showing information 2031c and a memory dump update flag 2032c for the storage device 20. Thus, the memory update information management table 203 includes tables showing information for each storage device 20 and a memory dump update flag, such as the first to third tables shown in Figures 4 to 6. In other words, the memory update information management table 203 manages information for each storage device 20 and a memory dump update flag for each maintenance terminal 10.

[0027] (Processing performed by the maintenance system) Figure 7 is a diagram showing an example of the processing flow of a maintenance system 1 according to a first modification of one embodiment of the present disclosure. Next, the processing performed by the maintenance system 1 will be described with reference to Figure 7. Here, it is assumed that three maintenance terminals 10a, 10b, and 10c are connected to the storage device 20. Here, it is assumed that maintenance terminal 10a transmits information identifying itself as a maintenance terminal 10 to the storage device 20. When there is an update in the information 2031 of the storage device 20, it is assumed that the memory dump update management function 202 sets the memory dump update flag 2032 of the target information in the memory dump update management table 203 (i.e., the memory dump update flags 2032a, 2032b, and 2032c of all maintenance terminals) to 1. In the following description, the processing performed by maintenance terminal 10a will be described. The processing performed by maintenance terminals 10b and 10c can be considered in the same way as the processing performed by maintenance terminal 10a.

[0028] The memory dump acquisition request means 101 of the maintenance terminal 10a transmits information identifying its own maintenance terminal 10 to the memory dump acquisition function 201 of the storage device 20 (step S29). The memory dump acquisition function 201 determines that the target maintenance terminal 10 is the maintenance terminal 10a based on the information identifying the maintenance terminal 10 from the maintenance terminal 10a (step S30).

[0029] When the maintenance terminal 10a requests the storage device 20 to take a memory dump, the maintenance terminal 10a's memory dump request means 101 checks the maintenance terminal 10a's previous memory dump presence information 102 to determine whether or not the previous memory dump exists in the maintenance terminal 10a's memory dump storage area 104 (step S31). If the maintenance terminal 10a's memory dump request means 101 determines that the previous memory dump does not exist in the maintenance terminal 10a's memory dump storage area 104 (NO in step S31), it takes the entire memory dump from the storage device 20's memory dump storage area 204. Specifically, the maintenance terminal 10a's memory dump request means 101 sends a request to take the entire memory dump to the memory dump taking function 201 (step S32). The memory dump taking function 201 receives the request to take the entire memory dump from the maintenance terminal 10a's memory dump request means 101. When the memory dump acquisition function 201 receives a request to acquire the entire memory dump, it acquires the entire memory dump in the memory dump storage area 204 (step S33). The memory dump acquisition function 201 transmits the acquired entire memory dump to the memory dump acquisition request means 101 of the maintenance terminal 10a (step S34). The memory dump acquisition request means 101 of the maintenance terminal 10a acquires the entire memory dump in the memory dump storage area 104 of the maintenance terminal 10a (step S35).

[0030] Furthermore, if the maintenance terminal 10a's memory dump acquisition request means 101 determines that there was a previous memory dump based on the previous memory dump presence / absence information 102 of the maintenance terminal 10a (YES in step S31), it sends a request to the memory dump acquisition function 201 to acquire the memory dump update area, which is the updated area of ​​the memory dump (step S36).

[0031] The memory dump collection function 201 receives a request to collect the memory dump update area from the memory dump collection request means 101 of the maintenance terminal 10a. When the memory dump collection function 201 receives a request to collect the memory dump update area, the memory dump update management function 202 extracts the target information for which the memory dump update flag is set to 1 in the memory dump update management table 203 (step S37). The memory dump update management function 202 instructs the memory dump collection function 201 to extract the memory dump of the target information (step S38). Then, the memory dump update management function 202 sets the memory dump update flag of the target information in the memory dump update management table 203 to 0 (step S39). Next, the memory dump collection function 201 uses the memory dump update area extraction function 2011 to extract the memory dump update area, which is the updated area of ​​the memory dump of the target information (step S40). The memory dump acquisition function 201 transmits the extracted memory dump update area, along with its target information, to the memory dump acquisition request means 101 of the maintenance terminal 10a (step S41). The memory dump acquisition request means 101 of the maintenance terminal 10a instructs the memory dump synthesis function 103 of the maintenance terminal 10a to synthesize the previous memory dump with the received memory dump update area, and the memory dump synthesis function 103 of the maintenance terminal 10a synthesizes the previous memory dump with the received memory dump update area (step S42). As a result, the maintenance terminal 10a has obtained a complete memory dump.

[0032] (advantage) The maintenance system 1 according to the first modification of one embodiment of the present disclosure has been described above. In the maintenance system 1, the maintenance terminal 10a transmits information identifying itself to the storage device 20. The storage device 20 determines that the target maintenance terminal 10 is the maintenance terminal 10a based on the information identifying the maintenance terminal 10 from the maintenance terminal 10a. With this maintenance system 1, the storage device 20 can identify the target maintenance terminal 10 (maintenance terminal 10a in the example described here) from among a plurality of maintenance terminals 10.

[0033] <Second Modification of Embodiment> A maintenance system 1 according to a second modification of one embodiment of the present disclosure may include a plurality of storage devices 20. In the maintenance system 1, if there are a plurality of storage devices 20, the maintenance terminal 10 can identify the target storage device 20 when checking for the presence or absence of a previous memory dump, or when combining the previous memory dump with the received memory dump update area, by acquiring information identifying the storage device 20 together with the memory dump.

[0034] Next, a maintenance system 1 according to some embodiments of the present disclosure will be described. Figure 8 is a diagram showing an example of the configuration of a processing system 700 according to some embodiments of the present disclosure. As shown in Figure 8, the processing system 700 is a processing system comprising a storage device 701 and a maintenance terminal 702. The storage device 701 comprises a management means 7011 that manages whether or not there has been an update for each log information of the storage device 701 divided into storage areas, and a transmission means 7012 that transmits only the log information of the storage device 701 within the updated area to the maintenance terminal 702. The maintenance terminal 702 comprises a synthesis means 7021 that synthesizes the log information of the storage device 701 received from the storage device 701 and the memory dump it holds.

[0035] The processing system 700 can be implemented, for example, using the functions of the maintenance system 1 illustrated in Figure 1. The storage device 701 can be implemented, for example, using the functions of the storage device 20 illustrated in Figure 1. The maintenance terminal 702 can be implemented, for example, using the functions of the maintenance terminal 10 illustrated in Figure 1. The management means 7011 can be implemented, for example, using the functions of the memory dump update management function 202 illustrated in Figure 1. The transmission means 7012 can be implemented, for example, using the functions of the memory dump acquisition function 201 illustrated in Figure 1. The synthesis means 7021 can be implemented, for example, using the functions of the memory dump synthesis function 103 illustrated in Figure 1.

[0036] Next, the processing performed by the maintenance system 1 according to some embodiments of this disclosure will be described. Figure 9 is a diagram showing an example of the processing flow of the maintenance system 1 according to some embodiments of this disclosure. Here, the processing of the maintenance system 1 will be described with reference to Figure 9.

[0037] In a processing system 700 comprising a storage device 701 equipped with management means 7011 and transmission means 7012, and a maintenance terminal 702 equipped with synthesis means 7021, the management means 7011 manages whether or not there are updates for each log information of the storage device 701 divided into memory areas (step S101). The transmission means 7012 transmits only the log information of the storage device 701 within the updated area to the maintenance terminal 702 (step S102). The synthesis means 7021 synthesizes the log information of the storage device 701 received from the storage device 701 with the memory dump it holds (step S103).

[0038] The above describes several embodiments of the maintenance system 1 according to this disclosure. This maintenance system 1 can improve convenience.
