Du-Pip4 - IBM Application System/400 Service Information

DU-PIP4
This procedure helps determine when the disk
drive and logic card should be exchanged for unit
reference codes FFF5, FFF6, FFF8, and FFF9.
Unit reference codes FFF5, FFF6, FFF8, and
FFF9 indicate temporary errors. However, when
the number of these errors reaches a threshold
count, the disk drive and logic card assembly
should be exchanged at the customer's conven-
ience, before the errors become permanent.
