network card speed changing after server reboot

Records Management — Tue, 17 May 2005 10:27:44 GMT

I have a RP2470 server running HPUX 11i. The nic card was set to 100 FD, but after the server rebooted it's now set to 10 HD.
I thought the /etc/rc.config.d/hpbtlanconf file controlled this? This file looks like this:
#####################################################################

HP_BTLAN_INTERFACE_NAME[0]=lan0
HP_BTLAN_STATION_ADDRESS[0]=
HP_BTLAN_SPEED[0]=100FD

###########################################################################
Why did the setting change?

These settings are not normally changed by anyone except the systems administrator.

If the lan connection were set to 10 HD at the switch, I suppose these settings could be changed by teh system, but that seems very unlikely.

I would check and see if another system administrator made the change, or perhaps while you were changing to 100FD you failed to save the config file.

Perhaps check the permissions on hpbtlanconf, maybe you can't write to it.

The line in the hpbtlanconf file is:
HP_BTLAN_SPEED[0]=100FD
and hasn't been modified since Jan 28 2005.

Why when the server came back up from a reboot the speed was 10HD?

roanyc # lanadmin -x 0
Speed = 100 Half-Duplex.
Autonegotiation = On.

I had to manually set it back to 100FD by command: lanadmin -x 0 100FD

If if your hpbtlanconf file is correct then check with switch port. It should be configured as autoneg or desired speed.

Maybe that's not the right conf file. It depends on the driver (check with ioscan):

btlan hpbtlanconf
btlan0 hpeisabtconf
btlan1 hpbasetconf
btlan3 hpbase100conf
btlan4 hpgsc100conf
btlan5 hppci100conf
btlan6 hpsppci100conf

When I do an ioscan the driver says "igelan".

I don't see that in the list from the response above.

which conf file should I modify for this driver?

roanyc # ioscan -fnClan
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/1/2/0 igelan CLAIMED INTERFACE HP PCI 1000Base-T Core

The hpbtlanconf file will have no effect on the Gigabit lan card.

I think you are better off leaving the card itself at AUTONEG and hard setting the switch port you are plugged into. If you ever want to go the full 1 Gb speed, the card will HAVE to be set to AUTONEG.

I believe the problem you are seeing is due to the switch port config.

The configuration file for the igelan driver is /etc/rc.config.d/hpigelanconf.

In the file, set to:

HP_IGELAN_INTERFACE_NAME[0]=lan0
HP_IGELAN_STATION_ADDRESS[0]=
HP_IGELAN_SPEED[0]=100FD

until you plug into a 1GB port.

Hi,

Changing it in /etc/rc.config.d/hpigelanconf should do it. Also check switch port settings as guided earlier to the desired speed.

HTH,
