  As shown in FIG. 1, the information processing system according to the present embodiment includes a plurality of servers (servers 102 to 104) and a plurality of peripheral devices (peripheral devices 105 to 110), which correspond to the system configuration in advance. Connected according to the configuration instructions created Further, the server 101 is connected to the servers 102 to 104 via the network 111. The configuration in FIG. 1 is merely an example, and any configuration that includes peripheral devices shared by a plurality of servers may be used. The number of servers and peripheral devices and their connection configurations are not limited to those shown in the figure.

  The server 101 includes at least a configuration information storage unit 112, a connection information acquisition unit 113, and an identification number setting unit 114. The configuration information storage unit 112 stores a configuration method to which the system is to be connected. The connection information acquisition / payment unit 113 refers to the configuration information storage unit 112, information indicating a connection state with one or a plurality of peripheral devices for each server (hereinafter referred to as server connection information), and each peripheral device. Information indicating the connection state with one or more servers (hereinafter referred to as peripheral connection information) is acquired. The identification number setting unit 114 assigns a unique identification number to the server and the peripheral device on the connection information acquired by the connection information acquisition unit 113.

  The servers 102 to 104 include at least connection information storage units 116 to 118, server mounting information acquisition units 119 to 121, and peripheral mounting information acquisition units 122 to 124, respectively. The connection information storage units 116 to 118 store server connection information and peripheral connection information acquired by the connection information acquisition unit 113. The server mounting information acquisition units 119 to 121 acquire information (hereinafter referred to as server mounting information) indicating an actual connection state with one or a plurality of peripheral devices for each server. The peripheral mounting information acquisition units 122 to 124 acquire information (hereinafter referred to as peripheral mounting information) indicating an actual connection state with one or a plurality of servers for each peripheral device.

  Furthermore, at least one of the servers constituting the system (here, the server 102) includes a connection information comparison unit 115 in addition to the connection information storage unit, the server mounting information acquisition unit, and the peripheral mounting information acquisition unit. Yes. The connection information comparison unit 115 has a function of collating server connection information and server mounting information, collating peripheral connection information and peripheral mounting information, and displaying an error when an erroneous connection is detected.

  In addition, the peripheral devices 105 to 110 constituting the system respectively include at least peripheral mounting information storage units 125 to 130. Peripheral mounting information storage units 125 to 130 store information (peripheral mounting information) indicating an actual connection state with one or a plurality of servers for each peripheral device.

  Next, with reference to FIG.1 and FIG.2, the confirmation method of the connection state in the information processing system of a present Example is demonstrated.

  First, the connection information which should be in the server 101 outside the system is acquired. Specifically, the connection information acquisition unit 113 refers to the configuration information storage unit 112 that stores a configuration instruction prepared in advance according to the system configuration, and connects to one or more peripheral devices for each server. Information indicating a state (server connection information) and information indicating a connection state with one or a plurality of servers for each peripheral device (peripheral connection information) are acquired.

  For example, when there is no connection error in FIG. 2A, the server (213: identification number described later) is the peripheral device (217) on the HW path 0/0/1 and the peripheral device on the HW path 0/0/2. (218) acquires that the peripheral device (219) should be connected to the HW path 0/0/3. Also, the peripheral device (216) acquires that it should be connected to the HW path 0/0/3 of the server (211) and the HW path 0/0/1 of the server (212), respectively.

  Further, when the connection information acquisition unit 113 acquires the connection information, the identification number setting unit 114 sets an identification number (numerical value in parentheses in the above description) for the server and peripheral devices constituting the system on the connection information. In this embodiment, a device having a unique identification number assigned at the time of manufacture is used, and a unique number is assigned to a server or peripheral device that does not have or has a unique identification number assigned at the time of manufacture. To do. Then, after setting the identification number, the server connection information and the peripheral connection information are stored in the connection information storage units 116 to 118 of the servers 102 to 104.

  Next, connection confirmation between the servers 102 to 104 and the peripheral device is performed. Specifically, the connection information comparison unit 115 instructs all servers constituting the system to acquire server mounting information. In each server, the server mounting information acquisition units 119 to 120 acquire information on peripheral devices connected to the server.

  For example, when there is a connection error in FIG. 2B, the server (213) has a peripheral device (216) on the HW path 0/0/1 and a peripheral device (218) on the HW path 0/0/2. It acquires that the peripheral device (219) is connected to the HW path 0/0/4, and transmits the acquired server mounting information to the server 102.

  Then, after the server 101 collects server mounting information of all the servers constituting the system, the connection information comparison unit 115 collates the acquired server mounting information with the server connection information stored in the connection information storage unit 116, Check the validity of the connection relationship and display error information if an incorrect connection is detected.

  In the above example, in the server connection information stored in the connection information storage unit 116, the server (213) has the peripheral device (217) connected to the HW path 0/0/1. Since the peripheral device (216) is connected to the HW path 0/0/1, the server (213) determines that there is an erroneous connection to the server (213). Similarly, in the server connection information, the server (211) has the peripheral device (216) connected to the HW path 0/0/3. However, in the acquired server implementation information, the server (211) has the HW path 0/0. Since the peripheral device (217) is connected to / 3, it is determined that there is an erroneous connection in the server (211).

  Next, the connection between the peripheral devices 105 to 110 and the server is confirmed. Specifically, the connection information comparison unit 115 instructs all servers constituting the system to acquire peripheral mounting information. In each server, the peripheral mounting information acquisition units 122 to 124 include peripheral mounting information (for example, server) indicating that the peripheral mounting information storage unit of the peripheral device connected to the server is connected to the peripheral mounting information storage unit. (Identification number / HW pass / peripheral device identification number) is written. As a result, a plurality of pieces of peripheral connection information are written in peripheral devices shared by a plurality of servers.

  For example, when there is no connection error in FIG. 2A, the peripheral device 216 receives the peripheral connection information “server 211, HW path 0/0/3, peripheral device 216” from the server (211). 212), peripheral connection information “server 212, HW path 0/0/1, peripheral device 216” is written. If this is erroneously connected, such as when there is a connection error in FIG. 2B, the peripheral device (216) receives “server 213, HW path 0/0/1, peripheral device 217” Peripheral connection information of the server (212) and "peripheral connection information of the server 212, HW path 0/0/1, peripheral device 216" is written respectively. The server (213) recognizes the peripheral device (216) as the peripheral device (217) due to an erroneous connection.

  Then, the peripheral mounting information acquisition units 122 to 124 notify the connection information comparison unit 115 after the writing is completed. After completing the writing of the peripheral mounting information of all the servers constituting the system, the connection information comparison unit 115 collects the peripheral mounting information of all the peripheral devices from the peripheral mounting information acquisition units 122 to 124 and stores them in the connection information storage unit 116. It verifies with the peripheral connection information for each peripheral device, confirms the correctness of the connection relationship, and displays error information when an erroneous connection is detected. Further, the connection information comparison unit 115 displays error information even when the mounting information cannot be collected.

  In the above example, for the peripheral device (216), the peripheral connection information stored in the connection information storage unit 116 is as shown in the table on the left side of FIG. 2A, but the acquired peripheral mounting information is shown in FIG. As shown in the table on the left side of b), since the upper part (shaded part) of the table does not match, it is determined that there is an erroneous connection in the peripheral device (216). Similarly, the peripheral connection information stored in the connection information storage unit 116 for the peripheral device (217) is as shown in the table on the right side of FIG. 2A, but the acquired peripheral mounting information is shown in FIG. As shown in the table on the right side of (b) and the lower part (shaded part) of the table does not match, it is determined that there is an erroneous connection in the peripheral device (217).

  The method of displaying error information is not particularly limited, and an error may be notified by blinking a lamp, or a message such as information indicating an erroneous connection part or information indicating a correct connection may be displayed. Good.

  As described above, in the information processing system according to the present embodiment and the method for confirming the connection state in the information processing system, the connection information comparison unit 115 is provided in an arbitrary server that configures the system. To quickly detect misconnections between the server and peripheral devices to verify information and server mounting information, and to check peripheral connection information and peripheral mounting information, and to display an error when an incorrect connection is detected. Therefore, it is possible to improve the connection work efficiency.

  In the above embodiment, the connection information comparison unit 115 is provided in the server 102. However, the connection information comparison unit 115 may be provided in another server, or the connection information comparison unit 115 may be provided in a plurality of servers. . Moreover, in the said Example, although the server 101 was provided in the high rank of the servers 102-104, you may perform the process of the server 101 in either of the servers 102-104.
