This is a read-write 32-to-36 octet globally unique identifier in canonical (readable) format for the physical server, defaulting to blank if the OS can't determine one. It provides the same unique server identity as cpqHoGUID but in a human-readable canonical string form more convenient for display or manual entry. For example, an administrator viewing this field in canonical format could copy it directly into an asset-tracking system rather than working with a raw binary GUID.
