A Library Controller Card That Is Removed From The Library - IBM TS3100 Setup, Operator, And Service Manual

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 contains
zeros (0s) in key VPD locations. Upon detection of these zeros, the library automatically attempts 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 might contain valid (non-zero) VPD data
left over from being installed in another library. If this action occurs, the library, which is expecting to see
zeros in the VPD area, instead detects valid VPD data, and does not know which copy of the VPD is the
correct one. It detects a "VPD Mismatch" and displays on the Operator Control Panel a screen entitled
"VPD Selection", where you must determine which copy of VPD is written to the new library controller
card.
If the message "VPD Selection" is displayed at the Operator Control Panel, carefully highlight the "VPD
from Enclosure" option to copy that version of the VPD to the new library controller card. Then, continue
with the procedure.
