What is chassisFanControllerVpdExists?

This boolean INTEGER (false or true) indicates whether the chassis fan bay identified by this row's chassisFanControllerVpdId actually has a fan module installed. An admin scans this flag across all fan rows to spot an empty fan bay, which reduces the chassis's cooling redundancy even if no active alarm has yet fired. For example, chassisFanControllerVpdExists returning false(0) for the row tied to chassisFan4 tells the admin that fan bay is currently empty and should be populated before the chassis loses another fan to failure.
