cpqDaPhyDrvPathHostConnector is a short DisplayString identifying the host connector that a specific physical drive access path is ultimately attached to, returning a NULL string if it can't be determined. This lets an admin trace a particular redundant path back to the exact physical connector it uses, separate from the drive's primary connector reported elsewhere. For example, when a specific path reports linkDown, an admin would use this connector identifier to find and inspect the correct cable.
