Abstract

A computer-readable medium is disclosed. The computer-readable medium stores a virtualized service tool application program for running on a computer running an existing operating system platform. The virtualized service tool application program has operating system software configured to execute as an internal operating system platform separate from the existing operating system platform, and that is configured with settings that permit the computer to communicate with one or more machines coupled to the computer. The virtualized service tool application additionally has a service module configured to perform service-related tasks for the one or more machines coupled to the computer.

Claims

1. A computer-readable medium storing a virtualized service tool application program for running on a computer running an existing operating system platform, the virtualized service tool application program comprising:

operating system software configured to execute as an internal operating system platform separate from the existing operating system platform, and that is configured with settings that permit the computer to communicate with one or more machines coupled to the computer; and

a service module configured to perform service-related tasks for the one or more machines coupled to the computer.

2. The computer-readable medium of claim 1, wherein:

the virtualized service tool application program is encrypted;

the virtualized service tool application program is associated with stored authorization information; and

the virtualized service tool application program can only be decrypted and executed if authorization information is provided that matches the stored authorization information.

3. The computer-readable medium of claim 2, wherein:

the virtualized service tool application program can only be decrypted and executed if authorization information is provided that matches the stored authorization information, and if the stored authorization information is valid.

4. The computer-readable medium of claim 1, wherein:

the computer-readable medium is a removable storage device configured to be connected to the computer; and

the virtualized service tool application program is configured to execute from the removable storage device.

5. The computer-readable medium of claim 4, wherein:

the removable storage device is configured to store data resulting from a diagnosis of the machine performed by the virtualized service tool application program.

6. The computer-readable medium of claim 4, wherein:

the removable storage device is configured to store a log of events that occur in connection with the invocation and use of the virtualized service tool application program.

7. The computer-readable medium of claim 1, wherein:

the computer-readable medium is a storage system on the computer; and

the virtualized service tool application program is not authorized for use.

8. A method of diagnosing one or more machines, the method comprising:

providing a service tool application program at a computer running an existing operating system platform, the service tool application program comprising;

a configuration code portion that permits the service tool application program to communicate with a remote machine without changing the communication settings of the existing operating system, and

a diagnostic application code portion that permits the service tool application program to run diagnostic tasks for diagnosing the remote machine;

executing the service tool application program; and

performing diagnostic tasks on the remote machine using the service tool application program.

9. The method of claim 8, further including:

storing authorization information at an authorization server system; and

permitting the service tool application program to be used for diagnostic tasks if the stored authorization information matches authorization information stored on the computer.

10. The method of claim 9, further including:

permitting the service tool application program to be used for diagnostic tasks if the stored authorization information matches authorization information stored on the computer, and if the authorization information is indicated as being valid.

11. The method of claim 9, further including:

preventing the service tool application program from being used if authorization to use the particular version of the service tool application program provided at the computer has been revoked.

12. The method of claim 8, wherein executing the service tool application program further includes:

executing the service tool application program from a removable storage device being accessed by the computer.

13. The method of claim 12, further including:

storing, in the removable storage device, data resulting from a diagnosis of the machine performed by service tool application program.

14. The method of claim 12, further including:

storing, in the removable storage device, a log of events that occur in connection with the invocation and use of the service tool application program.

15. The method of claim 8, wherein providing the service tool application program at the computer further comprises:

installing the service tool application program in a storage system on the computer.

16. The method of claim 8, wherein providing the service tool application program at the computer further comprises:

accessing a removable storage device by the computer, the removable storage device storing the service tool application program.

17. A computer-readable medium storing a virtualized control module application program, the virtualized control module application program comprising:

operating system software that is configured with settings that permit the computer readable medium to execute the virtualized control module application program and to communicate with a machine coupled to the computer readable medium via a communication interface; and

control software configured to control a part of the machine.

18. The computer-readable medium of claim 17, wherein:

the computer-readable medium is a removable storage device configured to execute the operating system software and control software.

19. The computer-readable medium of claim 17, wherein:

the virtualized control module application program is encrypted.

20. The computer-readable medium of claim 17, wherein the computer-readable medium further stores a virtualized service tool application program configured to perform services on the control software.
