Your customer wants to make sure that that each server profiles have only volume defined...

The customer should verify the consistency checking level for SAN storage in the server profile. In HPE OneView, server profile templates have settings that define whether differences in storage configurations between the template and the server profiles are considered inconsistencies. If the consistency checking for SAN storage is not enabled or set to a relaxed level, adding an extra volume to a server profile may not trigger an inconsistency report.

Option C (Correct): Ensuring that the consistency checking for SAN storage is properly configured will detect deviations.

Option A: The state of SAN connections affects connectivity, not template compliance.

Option B: FC network definitions are important but not directly related to template consistency checks.

Option D: Licensing issues would prevent functionality but not affect consistency reporting.
