Abstract

Configuration information settings for a storage device are made highly reliable and facilitated. The storage device includes a service processor for setting storage device configuration information, and a terminal device connected to the service processor via a private line to send a command group, received from an operator and related to the storage device configuration information, to the service processor. The service processor also includes a device for determining approval or denial of execution of the command group prior to execution of the command group received from the terminal device.

Claims

1. A storage device comprising:

a service processor configured to set configuration information of the storage device, wherein the service processor receives, from a terminal device, a command group described on a script sheet related to the configuration information of the storage device and first digest data based on the command group described on the script sheet, the first digest data indicating that a content of the script sheet is valid,

wherein the service processor creates second digest data based on the command group described on the script sheet received from the terminal device, compares the first digest data with the second digest data, and determines approval or denial of execution of the command group, based on results of the comparison, prior to execution of the command group received from the terminal device, and maintains with a history management module information about command groups for which execution is denied.

2. The storage device according to claim 1, wherein the service processor decrypts, by using a secret key, the first digest data that is encrypted by using the secret key at the terminal device.

3. The storage device according to claim 1, wherein the command group is used by the service processor to set a structure of the storage device.

4. The storage device according to claim 1, wherein the command group contains variables required for execution of commands by the service processor.

5. The storage device according to claim 1, wherein the script sheet includes a group of operations relating to addition and deletion of path definition information for connection of a host device and a logical volume of the storage device.

6. The storage device according to claim 1, wherein the script sheet includes a setting procedure that describes respective settings as argument parameters for setting nomenclatures and information required for settings thereof.

7. The storage device according to claim 1, wherein the script sheet includes the command group is determined to be valid by a reliable operator guaranteeing that no tampering has occurred before input into the storage device.

8. The storage device according to claim 1, wherein the digest data and the second digest data is created by compressing the script sheet containing the command group.

9. The storage device according to claim 1, wherein the service processor is further configured to compare an information set of the script sheet to a specification file corresponding to a user of the storage device and to thereby determine if the script sheet meets predetermined requirements of said user.

10. A method of setting configuration information of a storage device comprising:

performing at a terminal device a validity check of a script sheet having described thereon a command group, the command group relating to the configuration information of the storage device;

determining if the script sheet is valid;

creating first digest data based on the command group if it is determined that the script sheet is valid;

sending, to a service processor, the command group described on the script sheet and the first digest data;

receiving, at the service processor, the command group described on the script sheet and the first digest data,

creating second digest data based on the command group described on the script sheet received from the terminal device;

comparing the first digest data with the second digest data;

determining approval or denial of execution of the command group, based on results of the comparison, prior to execution of the command group received from the terminal device; and

maintaining, at the service processor, information about the command group when execution of the command group is denied.

11. The method according to claim 10, further comprising:

decrypting, by using a secret key, the first digest data that is encrypted by using the secret key at the terminal device.

12. The method according to claim 10, further comprising:

obtaining an information set from the script sheet;

comparing the information set to a specification file corresponding to a user of the storage device; and

determining if the script sheet meets predetermined requirements of said user based on comparing the information set and the specification file.
