The Library Controller Card contains a copy of the vital product data (VPD) for
your library. The VPD contains your current library configuration. A backup copy
of this VPD is contained within the electronics of the Library Enclosure. When the
Library Controller Card is replaced, the new replacement card should contain zeros
(0's) in key VPD locations. Upon detection of these zeros, the library will
automatically attempt to write VPD data to the new Library Controller Card from
the backup copy of the VPD contained in the Library Enclosure. In rare
occurrences, the new Library Controller Card may contain valid (non-zero) VPD
data left over from having been installed previously in another library. If this
occurs, the library, which is expecting to see zeros in the VPD area, will instead
detect valid VPD data, and will not know which copy of the VPD is the correct
one. It will detect a "VPD Mismatch" and display on the Operator Control Panel a
screen entitled "VPD Selection", where it is asking you to determine which copy of
VPD should be written to the new Library Controller Card.
