And the like, and an iSCSI initiator name that can be connected to a predetermined logical unit is automatically set.

  For example, the parameter resolution method such as the automatic iSCSI initiator name is based on a one-time password issuing technique, and a server (hereinafter referred to as OTIN) that issues a short-term iSCSI initiator name (hereinafter referred to as a one-time iSCSI initiator name). This is realized by using a (One Time Initiator Name) server; that is, an OTIN server is a kind of iSCSI initiator name server).

  The OTIN server issues a one-time iSCSI initiator name corresponding to a predetermined logical unit based on a connection request (that is, a target portal connection request) from the network appliance terminal device to the iSCSI target device. Then, the network appliance terminal apparatus that has received the one-time iSCSI initiator name automatically sets the one-time iSCSI initiator name and automatically connects to the desired logical unit.

  The validity of the one-time iSCSI initiator name can be arbitrarily set, for example, a period from the issuance time of the one-time iSCSI initiator name to a predetermined elapsed time (for example, 1 minute), or The period until the iSCSI login using the one-time iSCSI initiator name succeeds only once may be used.

  In addition, the uniqueness regarding the one-time iSCSI initiator name includes information such as the domain name in the OTIN server, the generation time of the one-time iSCSI initiator name, the session number at the time of connection from the network appliance terminal in the one-time iSCSI initiator name, These elements may be secured by checking with an OTIN server.

  Next, the OTIN server 10 that has received the request resolves the iSCSI target name D3 corresponding to the index information D9, and confirms that the logical unit specified by the index information D9 is in an “unconnected” state. After that, an iSCSI initiator name D6 corresponding to the index information D9 is generated, and information (for example, generation date and time) related to the validity of the iSCSI initiator name D6 is recorded. Then, the iSCSI initiator name D6 and the iSCSI target name D3 are notified to the Web server 9 (M33 in FIGS. 11 and 12).

  The connection state of the logical unit specified by the index information D9 is preferably stored in the OTIN server 10.

The notified LU name D4 is notified to the iSCSI target device 4 (M37 in FIGS. 11 and 13). Preferably, when the OTIN server 10 resolves the LU name, the OTIN server 10 connects the logical unit indicated by the LU name (for example, the connection of the logical unit stored in the OTIN server 10). Confirm that the (Status) is "Not connected" status.

  Next, the iSCSI target device 4 notifies the mount request to the logical unit 6 corresponding to the LU name D4 (M8 in FIG. 11).
