Abstract

Techniques for recovering an enclosure are provided. A recovery program is retrieved from a recovery program repository. Results from a plurality of diagnostic tests are retrieved. The diagnostic test results are analyzed with the recovery program. The recovery program determines an enclosure recovery action. The enclosure is recovered using the determined recovery action.

Claims

1. A method comprising:

retrieving a recovery program from a repository;

retrieving results from a plurality of diagnostics tests from an enclosure;

analyzing the results with the recovery program to determine a type of recovery;

recovering the enclosure based on the determined type of recovery

determining a set of the plurality of diagnostic tests that do not have results; and

executing the determined set of diagnostic tests.

2. The method of claim 1 further comprising:

determining, based on the recovery program, a set of desired diagnostic tests;

determining a subset of the set of desired diagnostic tests that are not installed; and

retrieving the subset of diagnostic tests from a repository.

3. The method of claim 1 wherein determining the type of recovery further comprises:

analyzing the results to determine which of the plurality of diagnostic tests have failing results; and

selecting the type of recovery that will resolve the greatest number of diagnostic test failures.

4. The method of claim 1 further comprising:

rerunning the plurality of diagnostic tests; and

reanalyzing results of the rerun of the diagnostic tests to determine if the enclosure recovery was successful.

5. The method of claim 1 further comprising:

displaying the determined type of enclosure recovery; and

receiving authorization to initiate the determined type of recovery.

6. The method of claim 4 further comprising:

repeating the method if the enclosure recovery was not successful.

7. A non-transitory processor readable medium containing thereon a set of processor readable instructions, which when executed by a processor cause the processor to:

connect to a recovery program repository to retrieve a latest version of a recovery program;

execute the recovery program, wherein the recovery program comprises instructions to;

retrieve results of a plurality of diagnostic tests from an enclosure;

analyze the results to determine a first recovery action;

execute the first recovery action on the enclosure;

determine a success status of the first recovery action;

store the success status, the analysis results, and the diagnostic test results to a recovery failure repository when the success status indicates failure, wherein the recovery program is modified based on the recovery failure repository;

retrieve a current version of enclosure firmware from a firmware repository; and

reinstall the current version of the firmware.

8. The non-transitory medium of claim 7 wherein the recovery program further comprises instructions to:

determine a set of diagnostic tests that are not available;

retrieve the set of unavailable diagnostic tests from a diagnostic test repository;

determine for which diagnostic tests results are not available; and

run the diagnostic tests for which results are not available.

9. The non-transitory medium of claim 7 further comprising instructions to:

store the success status, the analysis results, and the diagnostic test results to a recovery failure repository when the success status indicates success.

10. The non-transitory medium of claim 7 wherein the recovery program further comprises instructions to:

rerun the plurality of diagnostic tests; and

analyze results of the rerun of the plurality of diagnostic tests to determine if recovery was successful.

11. The non-transitory medium of claim 7 wherein the recovery action further comprises instructions to:

retrieve a latest version of enclosure firmware from a firmware repository; and

install the latest version of the firmware.

12. A system comprising:

a recovery program repository to store a recovery program;

a diagnostic test repository to store a plurality of diagnostic tests; and

a recovery failure repository to store results of execution of the recovery program;

wherein a recovery device retrieves the recovery program from the recovery program repository, retrieves any missing diagnostic tests from the diagnostic test repository, analyzes the results to determine which of the plurality of diagnostic tests have failing results, selects the type of recovery that will resolve the greatest number of diagnostic test failures, executes the recovery program on an enclosure, and stores the results of the recovery program to the recovery failure repository.

13. The system of claim 12 further comprising:

a firmware repository to store enclosure firmware versions, wherein the recovery program retrieves an enclosure firmware version from the firmware repository and applies the retrieved firmware version to the enclosure.
