Use case: Running sgpdd-survey against devices that do not support the sg_readcap query. Scenario 1: Running sgpdd-survey against a md (software) RAID device. Expectation: When sg_readcap fails to read from the device, sgpdd-survey should exit with an appropriate message and exit code. Notes: The sg_readcap command is called twice in sgpdd-survey. The first time it fails a default value of 512 is assigned to block size. After it fails on the second invocation, sgpdd-survey exits with an erroneous suggestion. Implementation: Suggest that sgpdd-survey exit with an appropriate message after the first failure of sg_readcap. |
