Lan Interface

Domenico_5 — Fri, 29 Mar 2002 10:25:53 GMT

Hi to all

I have this scenario: 2 A500 (a500a a500b) in cluster with 3 lan interface.
All work correctly, but for lan0 on a500a I can switch to 10 from 100 and on a500b I can't do it.
The server are identical (O.S.,Patch,HW)

tnx

Could you attach the following in a text file?

ioscan -fnkClan

lanscan

lanadmin

tail -30 /var/adm/syslog/syslog.log

How are you trying the switch.
lanadmin or sam. Is there an autosensing switch involved or do you need to manually configure the port.

Later,
Bill

hi bill

I have used sam, but with lanadmin is the same.

I have iverted the port on th switch where they are connected, but whit the same result.

The driver used for the lan is btlan3 for both server.

it's crazy!!!

Hi
Are you able to Linkloop first. Also make sure that your switch is communicating in the data layer level.If it is set to ip level it may have the problems you indicate.

Hi

Forgot to say about nettl.LOG*.look into /var/adm/nett* and see whether something has been logged by the system. Do this
netfmt -Nlf /var/adm/nettl.LOG00 > somefile
cat somefile.

I am wondering if the /etc/rc.config.d/
hpbase100conf are the same.

Also have you tried using lanadmin to
set the lan speed?

Hi,

Make sure the switch port on which this lan port is conencted is set to fixed 100mbps , full duplex, disable the auto neg both on the switch and the server lan port. Try to configure the lan port to fixed 100mbps , try sam. Use lanadmin and see if you can change the lan port settings from the command line. Do "man lanadmin" for more info on the command line sytax.

Hope this helps.

Hi,

do a "scancl". This will generate a file in /tmp by dafault. This will tell you if all your interfaces are working. You should see the lan connection okay for all working lan connection connected to the network.

Hope this helps.
