[LU-4240] sgpdd-survey exits with misleading message

Thu, 28 Nov 2013 22:20:17 +0000

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.
