Abstract

Providing a volume to a host computer by a storage system is automated for ensuring that an appropriate version of a storage control software is installed on a storage control module of the storage system that manages access of the host computer to the volume. When the volume on the storage system is allocated for use by the computer, a control module on the storage system is designated for managing the access to the volume. An operating system to be used on the computer when accessing the volume is determined, and a compatible version of the storage control software is uploaded and installed on the storage control module. Multiple storage control modules may be provided on the storage system and virtual machines may be used on the storage control modules for enabling simultaneous operation of more than one version of the storage control software on each storage control module.

5. A method according to claim 1, further including steps of

retrieving a volume image into the first volume on the first storage system, the volume image including said operating system to be used on the computer and an application program to be operated on the computer;

and

installing the determined version of the operating system, which is stored in said first volume, onto said computer from said first volume after said step of installing the version of the storage control software on the control module of the first storage system.

6. A method according to claim 5, further including steps of

creating a virtual machine on said computer prior to installing said step of installing the operating system onto said computer;

and

installing said determined version of said operating system onto said virtual machine on said computer.

7. A method according to claim 1, further including steps of

archiving said first volume to an archive volume on a second storage system in communication with said first storage by copying the contents of said first volume, including the operating system to the archive volume;

and

storing an information on the version and vendor of operating system included in the archive volume.

21. A method according to claim 4, further comprising:

controlling at least one of execution priority or ratio among the virtual machines based on an execution priority or ratio for each of the virtual machines.

8. An information system comprising:

a first storage system, said first storage system including a plurality of storage devices for providing physical storage capacity for creating logical volumes;

a plurality of control modules in said first storage system for controlling access to said logical volumes;

a first computer in communication with said first storage system for accessing a first volume of said logical volumes;

wherein said first storage system is configured to select a first control module out of said plurality of control modules for controlling access of said first computer to said first volume;

wherein said first storage system is configured to install a particular version of a storage control program to said selected first control module, said particular version of said storage control program being determined to be compatible with a version of an operating system determined to be used on said first computer when accessing said first volume, based on a relationship between one or more versions of the operating system and one or more versions of the storage control program for controlling storing data sent from the operating system to a volume in the first storage system.

9. A system according to claim 8, further comprising

a software repository in communication with the first storage system via a communications network, wherein said first storage system is configured to receive the particular version of the storage control software over the communications network from the software repository.

10. A system according to claim 8, further comprising

a virtual machine program installed on said first storage system for configuring a virtual machine on the first control module of the first storage system prior to installing the particular version of the storage control software so that the particular version of the storage control software is installed on the virtual machine configured on the first control module.

11. A system according to claim 8, further comprising

a second computer in communication with the first storage system, wherein said second computer is configured to determine the determined version of the operating system to be used on the first computer, and determine the particular version of the storage control software that is compatible with the operating system.

12. A system according to claim 8, further comprising

a second storage system in communication with the first storage system, wherein said first storage system is configured to retrieve a volume image from the second storage system into the first volume on the first storage system, the volume image including said determined version of said operating system to be used on the first computer and an application program to be operated on the first computer.

13. A system according to claim 8, further comprising

a virtual machine program on said first computer for creating a virtual machine on said first computer prior to installing the determined version of the operating system onto said first computer, so that the determined version of the operating system is installed onto said virtual machine on said first computer.
