ATTOCelerityFCLog utility
The Cele
rity FC host adapter driver does not use the system log to communicate driver events because
it has
limited resources and events are easily lost. Instead, the driver logs events internally; you can
retrieve them using the AT TOCelerity FCLo g utility.
It is difficult to predict the number of events, but the driver’s internal event log should be large enough
to hold all
events from the tim e the driver is loaded until the time ATTOCelerityFCLog is run. If the
event log becomes full, the driver continues to log events, overwriting the earliest events with the most
recent events. If event data is lost, ATTOCelerityFCLog d isp lays ...Lost X bytes...,where X
is the
number of bytes lost.
The AT
TOCelerityFCLo g utility displays events as they are logge d by the driver. You can set the utility
as a
st
artup i tem to always retrieve events in the background, but this can cause a slight per formance
degrad ation.
When events are retrieved and displayed, they ca nnot be redisplaye d, even if they are not overwritten
by subsequent events. If you want to save events for future reference, save the Terminal output or use
stan
dard redirection when starting ATTOCelerityFCLog to save the output to a file.
Each
event begins with a channel identifier, Channel X.Y.Z,where X is the PCI bus number, Y is the PCI
dev
ice number, and Z is the PCI function number. D river initialization messages can be logged before
thi
s
information is available.
You can specif y the t ypes of events that are logged using the -e System NVRAM option. Each bit in the
mask
corresponds to a group of related messages.
