Core LAN adaptor failed??

[Eugene Osipov]

Dear all,

Please help with following concern.

I got A-class server (A400) with 3 UTP connectors: one for 10BASE-T lan console, one for 10/100BASE-T lan and one for web console. All was working fine. Then server had some transportation. Afterward first time I turn it on I receive this dmesg:
[..skipped..]
btlan3: NOTE: MII Link Status Not OK - Switch Connection to AUI at 0/0/0/0....
btlan3: timeout: DMA timeout occurred at 0/0/0/0
btlan3: reset state is 550 at 0/0/0/0....
btlan3: WARNING: AUI Loopback Failed at 0/0/0/0....

btlan3: WARNING: AUI Loopback Failed at 0/0/0/0....
[..skipped..]

.. and lan at 0/0/0/0 is not working. No "link" LED, no nothing. Although ioscan shows this hardware path to be OK. Lan console and web-console are working fine.

What is it??

Thanks a lot

Eugene

Hi Eugene,

I don't think this is a hardware problem, because you say that the cards is claimed and known by the kernel.

Possible solutions you can try,

1. Use another network cable, maybe the one you use is defect.

2. If you are connected to a switch, check is all the port values are fixed, like speed and duplexmode. So turn all auto-negotiation off on the port that the A-class is connected to.

Dear Marcel,

LAN cable is good, I have checked it first as usual. In fact the same LAN cable is working fine with lan console and web console. Switch (I have HP ProCurve 2512) does not seem to be a problem too. LAN port is not working even after connecting server directly to hub (without switch). I know for sure that this configuration was OK before.

Anyway, thanks for your time!

I have seen hardware problems on AUI adapters
show the same on a K AUI->10BT transc.

But normally this is rare if you see it on the
ioscan and
lanscan ???
There should be no problem.
Make sure the ioscan instance number for
the lan adaptor is shown in the lanscan output
and that lanscan shows the interface up.

You can change the IP address with
ifconfig

Later,
Bill

Dear Bill,

Yes, I can see it on ioscan:

What does
# ifconfig lan0
report
Are all the IP?depinitions valid.
How are you assigning your IP..
bootp, dhcp or static.
Has you IP changed since the move?

Use
# set_params ip_address
if so and watch out for /etc/hosts

# lanadmin
can also help configuring/troubleshooting the
card itself.

Do you have OnlineDiagnostics installed?
This is the sure fire way to find out if
you got a hardware problem.

Hi!

Problem is solved. It was bad port connector + NIC misconfiguring (a mess with ethernet and 802.3....).

Thank you Marcel and Bill!

Take care,

Eugene

well done..
that was quick enough too!

Have fun,
