btlan3 - Problem ??

[Fredric Persson]

I have a problem to config a btlan3 interface, it has worked earlier but now it doesn?t. It is a A5838A - Dual port 100baseT/X/dual port Ultra 2 SCSI Combo Interface card . Connecting it to a backup switch (10/100Mbit HP Procurve), but unable to send/recieve data.

The interface flips between availible/unavailbe and there are msg in the syslog that says: vmunix:btlan3:Tx timeout: DMA timeout occurred at 0/4/0/0/0/6/0.

I have installed the latest patches, but I still don?t know what the problem is. I have link on both the server and the switch. Also tried to change port setup (10/100/HD/FD).

Could it be the HW ?

Thanks!

This could be a number of things.
I suggest you check the following:
hub/switch port (try another known working port
cable (try another known working cable)
card port (try the other port)
Ensure the patches for btlan3 are installed and configured by checking with swlist. to ensure all sw is configured do:
swlist -l fileset -a state | grep -e install -e transient -e corrupt

You should not get any thing listed. If you do, this may be a part of the symptom.

Failing that, change the card.

is there any traffic on th eother 10/100 port and/or the SCSI ports? if so, and if you remove that traffic, do the DMA timeouts go away?

[Fredric Persson]

Currently there is no trafic on the other port. I have tried to config that port also, but it doesn?t work either.

Comment out ident in /etc/inetd.conf file, restart inetd and see?. We had a similar kind of problem and finally found the sendmail using ident as the culprit.

the ident field is already outcommed.
