Thanks Alexander, I'm looking forward to trying it out. Good question, I'm not sure where it got the first part of the VPD serial number. The only other MS documentation I could find is this:
which has this information on VPD in it (although it seems general and not specifically for Failover Clustering):
g. Required Vital Product Data (VPD) pages: 0 Supported Pages, 80h: Serial Number, 83h: Device IDs.
i. For VPD Page 83, type 2 or type 3 descriptors must be returned and must be unique for each logical unit. Appropriate descriptors for multiport devices are required in addition to the type 2 or 3 descriptors. Devices that support aliases must also support the corresponding descriptor types. Vendor-specific device identifiers, if present, must use type 0 and follow the specified format, including correct page length; vendor specific identifiers are not a substitute for the mandatory type 2/3 descriptors.
ii. Page 80h (serial number) must be in ASCII.
