FIG. 9 is a diagram showing a processing flow of the maintenance support system 1 according to the embodiment of the present invention. The operation of the maintenance support system 1 will be described later with respect to the processing flow. In the following processing, the case where one of the connector portions 8 (SFP) of the plurality of storage devices constituting the electronic device equipment 4 in the data center fails is taken as an example. The electronic device equipment 4 is composed of a plurality of storage devices, and the storage device is composed of a plurality of storages as physical drives.

Before the start of the processing flow of FIG. 9 by the maintenance support system 1, the storage device detects the failure of the SFP, so that the management server 2 notifies the maintenance center that maintains the electronic device equipment 4 of the failure of the SFP. Then, when the maintenance staff arrives at the maintenance site, they attach the AR glasses 3 and notify the maintenance support system 1 of the start of maintenance work, thereby starting the processing flow of FIG. 9 by the maintenance support system 1. The processing of reporting the SFP failure from the management server 2 to the maintenance center that maintains the electronic device equipment 4 is performed as described with reference to FIG.

The position notification unit 11 acquires information on the SFP that is the failed component (step S91). Specifically, the location notification unit 11 uses the information for identifying the failed SFP included in the report sent to the maintenance center that maintains the electronic device equipment 4, and the information about the failed SFP is sent to the management server 2. Make a request. The component information table processing unit 24 of the management server 2 acquires the SFP information regarding the requested SFP from the storage unit 27, and transmits the SFP information table configured based on the acquired information to the maintenance support system 1. .. In this way, the position notification unit 11 acquires information on the SFP that is the failed component. The processing of the management server 2 here is performed as described with reference to FIG. As described with reference to FIG. 5, the SFP information table also includes information on the storage location including the target SFP and the SFP location.

The position notification unit 11 causes the AR glass 3 to display the layout drawing of the storage device including the failed component in order to guide the maintenance personnel to the failed SFP by using the SFP information table acquired from the management server 2. Perform the processing for. Further, the position notification unit 11 performs a process for causing the AR glass 3 to display the position of the failed component in the displayed layout drawing (step S92). FIG. 10 is an example of an arrangement diagram of a storage device including a failed component in the AR glass 3 by this processing. Reference numeral 101 in FIG. 10 shows an example of highlighting the position of the storage device including the failed SFP.

The AR glass 3 is provided with a positioning communication unit 33, and can identify the position of a maintenance person wearing the AR glass 3. The AR glass 3 requests position information at any time, and notifies the maintenance support system 1 of the requested position information. As a result, the maintenance support system 1 can grasp where the maintenance staff is in the layout diagram shown in FIG. When the position notification unit 11 recognizes that the maintenance personnel has approached the storage device including the failed SFP, the position notification unit 11 performs a process for causing the AR glass 3 to display the position of the failed component in the displayed layout drawing. conduct. FIG. 11 is an example of display on the AR glass 3 by this processing. As shown by reference numeral 101, the storage device including the failed SFP is highlighted, and as shown by reference numeral 111, the position of the storage including the failed SFP is highlighted. As a result, even in a data center equipped with a plurality of the same or similar devices, the maintenance staff can go to the device to be maintained without hesitation.

The position notification unit 11 identifies the position of the failed SFP in the image image by analyzing the image image sent from the AR glass 3, and performs a process of transparently displaying the specified component on the AR glass 3 (step S93). ). The process of step S93 is performed by the position notification unit 11 confirming that the maintenance staff has sufficiently approached the part to be maintained by the position information from the AR glass 3. The technology of transparent display for the position of the failed SFP from the image and the augmented reality is realized by using the technology of image recognition. It should be noted that other techniques may be used to realize transparent display for the position of the failed SFP and augmented reality from within the image. Reference numeral 121 in FIG. 12 shows an example of a transparent display for augmented reality of a failed SFP in the AR glass 3 due to this processing. This allows maintenance personnel to easily identify which SFP has failed.

The redundant configuration confirmation unit 12 confirms whether the failed SFP is in use by confirming the SFP information table acquired in step S91 (step S94). If the failed SFP is not in use (step S94: No), control is transferred to step S97.

On the other hand, when the failed SFP is in use (step S94: Yes), the redundant configuration confirmation unit 12 performs a process of confirming the switching SFP by the redundant setting for the failed SFP from the management server 2 (step S95). Specifically, when the failed SFP is in use, the redundant configuration confirmation unit 12 instructs the management server 2 to switch the path when the alternative path is not valid. The redundant configuration confirmation unit 12 acquires an SFP information table with updated information on the alternative path from the management server 2. At this time, the management server 2 switches the path using the multipath software of the business server.

When the redundant configuration confirmation unit 12 confirms that the path has been switched to the failed SFP, the replacement auxiliary unit 13 notifies the AR glass 3 used by the maintenance staff of information regarding the path switching. Further, the replacement assisting unit 13 notifies the AR glass 3 that the failed SFP can be replaced (step S96).

At this time, the exchange assisting unit 13 identifies the position of the SFP to be switched in the image image by analyzing the image image sent from the AR glass 3. Then, the exchange assisting unit 13 notifies the information regarding the SFP to be switched by transparently displaying the specified SFP on the AR glass 3. The technique of transparent display for the position of the SFP to be switched from the image and the augmented reality is realized by using the technique of image recognition. Further, other techniques may be used to realize the position of the SFP to be switched from within the image and the transparent display for augmented reality. Reference numeral 122 in FIG. 12 is an example of a transparent display for augmented reality of the SFP to be switched in the AR glass 3 by this processing. As shown in FIG. 12, it is preferable that the replacement auxiliary unit 13 performs a process for transparent display by augmented reality of the failed SFP indicated by the reference numeral 121 together with the SFP that switches the path indicated by the reference numeral 122. As a result, the maintenance staff can easily confirm that the SFP path has been switched.

The component confirmation unit 14 receives the code attached to the SFP to be replaced from the AR glass 3 and inquires to the management server 2 using the acquired code to see if the component whose code has been read is a defective component. Is performed (step S97). This process is started by reading the two-dimensional code 82 printed on the tag 81 attached to the SFP to be replaced by the maintenance staff with the camera 32 of the AR glass 3 and transmitting it to the maintenance support system 1. This two-dimensional code includes information such as a type for each part and specifications related to the part as shown in FIG. 13 as an example. When the component is an SFP, the two-dimensional code includes information on the support speed as well as the type. The management server 2 collates the information such as the type of SFP and the support speed sent from the maintenance support system 1 with the information such as the type of the SFP caused by the failure managed by itself and the support speed. In this way, the management server 2 confirms whether the component whose code has been read by the maintenance staff using the AR glass 3 is a failed component, and notifies the maintenance support system 1 of the result.

When the component confirmation unit 14 confirms that the SFP whose code has been read is a failed SFP by an inquiry to the management server 2, the maintenance staff gives an instruction to replace the SFP whose code has been read to the AR glass 3. Perform the notification process (step S98).

The maintenance staff who received the SFP replacement instruction from the maintenance support system 1 reads the code and replaces the SFP, and the maintenance work is completed.

As described above, the maintenance staff can confirm the redundant setting and switch if the redundant setting is made in the maintenance work of the environment where a large number of storage devices are installed such as a data center. As a result, maintenance personnel can carry out safe and efficient parts replacement work without stopping the business provided by the electronic device equipment.

As an embodiment, AR glass 3 is taken as an example as a portable device possessed by a maintenance worker. In this case, the maintenance staff can improve the work efficiency by expanding the reality while freeing both hands, but the work efficiency is not limited to this. For example, the portable device possessed by the maintenance staff may be a tablet device.

As one embodiment, the maintenance support system 1 has been described as a device separate from the portable device such as the AR glass 3. If the mobile device has sufficient processing power, the mobile device may be provided with the function of the maintenance support system 1.
