Logging and Tracing Messages

HP FDDI/9000 comes with an online message catalog that reports HP

FDDI problems, probable causes, and actions for you to take to correct

the problems. Messages are sent either to the system console or log ﬁles,

and come in the following format:

HP FDDI/9000 uses the nettl logging and tracing facility supplied with

HP- UX to capture, control, and format messages produced by HP FDDI.

When using nettl, note the following:

• log and trace messages are sent to the ﬁles /var/adm/nettl.LOG##

or /var/adm/nettl.TRC##

• all disaster messages are sent to the system console

• tracing and logging have an impact on system performance and

should be used judiciously

Listed below are some example commands.

• To examine the log ﬁle with message, cause, and action:

netfmt -v -file /var/adm/nettl.LOG00 -t 50

1041 MESSAGE HP-PB FDDI LAN driver received an

error from the adapter in path %s

indicating length mismatch on

transmission of a data packet.

CAUSE (Disaster) This is probably due to a

hardware problem on the adapter.

ACTION Execute the lanscan command to

identify the device logical unit of

the LAN adapter. Re-initialize the

adapter using fddiinit. If

initializing the adapter does not

solve the problem, reboot. If

rebooting is ineffective, notify your

HP representative.
