Link Incident Log

The Link Incident Log displays the 1000 most recent link incidents with the date
the incident occurred, the time it occurred, and the port on which the incident took
place. The information is useful to maintenance personnel for isolating port
problems [particularly expansion port (E_Port) segmentation problems] and repair
verification.
