Abstract

A method, apparatus, article of manufacture, and system are presented for establishing redundant computer resources. According to one embodiment, in a system including a plurality of processor devices and a plurality of storage devices, the processor devices, the storage devices and the management server being connected via a network, the method comprises storing device information relating to the processor devices and the storage devices and topology information relating to topology of the network, identifying at least one primary computer resource, selecting at least one secondary computer resource suitable to serve as a redundant resource corresponding to the at least one primary computer resource based on the device information and the topology information, and assigning the at least one secondary computer resource as a redundant resource corresponding to the at least one primary computer resource.

Claims

1. In a system including a management server, a plurality of processor devices, and a plurality of storage devices, the processor devices and the storage devices being coupled to the management server via a network, a method for the management server to establish a clustering system comprising:

storing storage device information relating to each of the storage devices;

receiving a command from a user interface for specifying at least one candidate of secondary storage devices to which data stored in a primary storage device can be copied and at least one candidate of secondary processor devices, the command having information for identifying a primary processor device and the primary storage device which are configured to be a primary computer resource; and

specifying at least one candidate of secondary storage devices corresponding to the primary storage device based on the storage device information, the at least one candidate of secondary processor devices corresponding to the primary processor device, and the at least one candidate of secondary storage devices and the at least one candidate of secondary processor devices being configured to be at least one secondary computer resource for the primary computer resource,

wherein the storage device information includes an IP address assigned to the each of the storage devices.

2. The method of claim 1, the method further comprising storing processor device information relating to each of the processor devices.

3. The method of claim 2, wherein the processor device information includes an IP address assigned to the each of the processor devices.

4. The method of claim 1, wherein if the primary storage device has a storage-based remote mirroring function, the at least one candidate of secondary storage devices is specified such that the at least one candidate of secondary storage devices also has the storage-based remote mirroring function.

5. The method of claim 1, wherein each of the plurality of processor devices includes clustering software for maintaining a clustering system.

6. The method of claim 5, wherein each of the plurality of processor devices includes a management agent.

7. The method of claim 6, wherein each of the plurality of processor devices includes a plurality of host ports.

8. The method of claim 1, wherein the primary computer source includes a first network interface device for the network and wherein the at least one secondary computer resource includes a second network interface device for the network.

9. The method of claim 1, wherein the at least one candidate of secondary processor devices is selected from the plurality of processor devices having processing capability equal to the primary processor.

10. The method of claim 1, wherein the user interface includes a graphic user interface (GUI).
