Description
CROSS REFERENCE TO RELATED APPLICATION This application is a continuation of international PCT application NO. PCT/JP/03/04366 filed on Apr. 4, 2003 and published as WO 03/085894 A1 on Oct. 16, 2003.
The present invention relates to a storage area network system (hereinafter referred to as �SAN system�) construction aid apparatus, a SAN system construction aid method and a SAN system construction aid program which reduce time, labor, cost and the like required when a SAN system is constructed.
FIG. 1 shows the basic configuration of the SAN system. In order to simplify the description, FIG. 1 shows the SAN system which connects one set of server 100 and one set of storage 200 by the fabric method using two sets of fiber channel switch (hereinafter referred to as �FC switch�) 300A and 300B and a fiber channel 400 using seven optical fibers.
The server 100 has two fiber channel ports 101 and 102 (hereinafter referred to as �FC port�) to which the fiber channel 400 is connected, and the storage 200 has four FC ports 201, 202, 203 and 204. The two FC switches 300A and 300B have FC ports 310A to 310H and 320A to 320H respectively as well as FC ports 310I and 320I to cascade-connect the FC switches.
FC port 101�FC port 310A FC port 102�FC port 320A FC port 310E�FC port 201 FC port 310F�FC port 202 FC port 320E�FC port 203 FC port 320F�FC port 204 by the fiber channel 400. In a fiber channel, an inherent ID code of world wide port name (hereinafter referred to as �WWPN�) as a given format configuration is set to FC ports. The FC switch has a zoning function (access control function) for dividing the connection relationship between the FC port of the server side and the FC port of the storage side using the WWPN peculiar to the FC port, and this zoning function dynamically controls the connection of the FC port of the server side and the FC port of the storage side.
The FC switches 300A and 300B are equipped with the zoning mechanisms 311 and 321 which fulfill the zoning function. In the construction of a SAN system, the zone division information which indicates the connection relationship between the zoning mechanisms 311 and 321 and the FC ports 101 and 102 of the server 100, the FC ports 201 to 204 of the storage 200 is set, and a logical connection path (hereinafter referred to as �access path�) between the FC ports 101 and 102 of the server 100 which makes access possible and the FC ports 201 to 204 of the storage 200 is set.
AP1: FC port 101�FC port 210 AP2: FC port 101�FC port 203 AP3: FC port 102�FC port 202 AP4: FC port 102�FC port 204 are set between the server 100 and the storage 200. When a SAN system is actually constructed, it is necessary to set the access path of the SAN system by determining the type and quantity of each device constituting the SAN system such as a server, a storage and an FC switch, physically connecting each server and each FC switch, and each storage and each FC switch by a fiber channel, and setting the zoning of each FC switch.
SUMMARY OF THE INVENTION To solve the above problems, the following technical measures are taken in the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS According to an embodiment of the present invention, a SAN system construction aid apparatus is provided in which at least one server having at least one fiber channel, at least one storage having at least one fiber channel port, and at least one fiber channel switch having a plurality of fiber channel ports are connected by a plurality of fiber channels, and which comprises a first information input device for inputting information concerning the server, the storage and the fiber channel switch device, a second information input device for inputting information concerning the physical connection by a plurality of fiber channels between the server, the storage and the fiber channel switch, an image making device for making a configuration image of a virtual SAN system which is physically connected by a plurality of fiber channels between the server, the storage and the fiber channel switch based on the information inputted from the first and second information input devices, and a display device for displaying the imaged made by the image making device
The SAN system construction aid apparatus comprises a third information input device for inputting information concerning the logical connection between the server, the storage and the fiber channel switch of the virtual SAN system, a display control device for adding an image indicating the logical connection to the configuration image of the virtual SAN system displayed in the display device based on the information inputted from the third information input device, and a recording device for recording, in a recording medium, information concerning the configuration of the virtual SAN system displayed in the display device and information concerning the logical connection of the virtual SAN system inputted from the third information input device.
Thus, when information concerning the devices of server, storage and fiber channel switch which are the constituents of the SAN system under consideration (for example, information about the type and manufacturer of these devices) is inputted, and information concerning the physical connection between the server, the storage and the fiber channel switch (more specifically, information indicating the connection relationship between the FC ports using an inherent world wide port name (hereinafter referred to as �WWPN�) set to each FC port) is inputted, a configuration image of a virtual SAN system which is physically connected by a fiber channel between the FC port of the server and the FC port of the fiber channel switch, and between the FC port of the storage and the FC port of the fiber channel switch is displayed on the display of the computer.
Information necessary for the construction of a SAN system is information concerning the server, the storage and the fiber channel switch (hereinafter referred to as �FC switch�) which are the basic devices constituting a SAN system (hereinafter referred to as �device information�), information concerning the physical access path by a fiber channel between these devices (hereinafter referred to as �physical path�), and information concerning the logical access path in which the server can access the storage via the FC switch. In this embodiment, to construct a SAN system using a fiber channel, each device of the server, the storage and the FC switch must be equipped with the FC port to which the fiber channel is connected.
The part of each FC port in the image displayed on the display 13 in which the server, the storage and the FC switch are arranged constitutes a GUI, and the designer of the SAN system construction aid apparatus 1 can set a physical path by designating the FC port which is physically connected by a fiber channel. When information of the physical path is inputted, the CPU 111 adds an image connected by the fiber channel to the image displayed on the display 13 in which the server, the storage and the FC switch are arranged based on the information. When the CPU 111 finishes the setting of the physical path by repeating this procedure, the CPU 111 makes a file of the information concerning the physical configuration of the SAN system displayed on the display 13 (including the system configuration drawing and the information of the physical path) (hereinafter, this file is referred to as �SAN system configuration file�), and stores the file in the RAM 113.
When a physical configuration image of a physical SAN system is completed, it is possible to set an access path using the configuration image. This access path is set by designating the FC port of the accessible server and the FC port of the storage in the same way as the setting of the physical path. When the information of the access path is inputted, the CPU 111 adds an image of the access path to the configuration image of the SAN system displayed on the display 13. When the CPU 111 finishes the setting of the access path by repeating this procedure, the CPU 111 makes a command for setting an access path to the SAN system which has been actually constructed from the access path setting information, and stores the file of the command (hereinafter, this file is referred to as �access connection command file�) in the RAM 113.
After the SAN system has been actually constructed based on the system design drawing by a virtual SAN system, as shown in FIG. 11, when a user inputs a �SAN system configuration confirmation request� from the input device 12 in the SAN management server 600 (YES in S10), the CPU 11 loads the SAN system configuration file stored in the RAM 113 to the work area of the RAM 113 (S11), obtains the physical configuration information (information of the physical path) from the actual SAN system via the LAN (S12), compares this information with the physical configuration information of the virtual SAN system (information of the physical path), and confirms whether the actual SAN system has been constructed as designed (S13).
When the user inputs an �access path automatic setting request� from the input device 12 in the state in which the physical configuration of the actual SAN system is the same as that of the virtual SAN system (YES in S15), the CPU 111 loads the access path connection command file stored in the RAM 113 to the work area of the RAM 113 (S16), and changes the access path set by the provisional WWPN in the access path connection command file to the access path set by formal WWPN obtained from the actual SAN system (S17), and after then, stores the access path connection command file in the RAM 113 again. (S18).
WORKING EXAMPLE 1 Described in this working example is the SAN system design to be implemented at an off-line time when the WWPN or WWNN of each port of each device (hereinafter referred to as �WWN�) has not yet been obtained.
WORKING EXAMPLE 2 In this working example, the physical connection of the actual system is implemented using the system design data made in working example 1 (access path connection command file) at an installation site (refer to FIG. 11).
FIG. 19 shows that information from the instances in the server to the media in the storage is constructed by setting the WWN information of the server and the storage (with each other) as access information to the switches using the WWN information which is unknown when the system is off-line designed and by re-booting the server. In FIG. 17, WWN information in terms of port information of port A. port B, port C, and port D is unknown, but in FIG. 19, the WWN of each port is known (�port A: WWN1,� �port B: WWN2,� �port C: WWN3� and �port D: WWN4�).
