speed / duplex issue on hp9000

golfnut — Fri, 24 Jun 2005 10:57:14 GMT

We have 2 hp 9000's. Both have same NICs. We have a speed / duplex issue on one of them. It refuses to go full duplex. It is currently working at half duplex 100M. Also the lanadmin command gives a core dump on displaying for the lan0. For lan1 it works fine.

Here are the relevant ouputs.

How can i see if there is difference in driver version?
Whenever I tried to manually change ti to full duplex the interface hangs.
There is a file call hpbasetconf. Will putting the information there fix the issue? We have it set properly on the working system?

thanks

Same OS on both machines? It looks to me like your problem system may be running 10.20 still.

lanadmin -x 0

Replace 0 with the actual number of the interface from lan display. lanscan will work to give you what you want.

If you need to change duplex and speed, lanadmin -X will do it.

Note that the swtich settings for 10/100 BT HP-9000 Nic cards must be manual. That means if the card is a 100, the switch must be 100 Base T manual, not autonegotiate.

To get that speed you may need a file called /etc/rc.config.d/hpbtlanconf to make speed work right at boot. You can look at the one on the good machine and copy/change the relavent information on the one giving you trouble.

If this is 1000 BaseT all switch and configuration settings must be auto negotiate.

Failure to meet these guidelines will result in tremendously slow network throughput.

Using lanadmin -X causes the interface to not respond.

Here something i saw.

The good machine has
ux01admlog.newcorp.com:0-kingkong-root $ swlist |grep -i lan
B3693AA C.03.05.00 HP GlancePlus/UX for s800 11.0
B3701AA C.03.05.00 HP GlancePlus/UX Pak for s800 11.0
J2759BA B.11.00.06 HP-PB 100BT LAN/9000
PHNE_19754 1.0 LAN product cumulative patch

See the patch for HP-PB

The trouble server has

ux01admlog.newcorp.com:0-godzilla-root $ swlist |grep -i lan
B3693AA C.02.40.000 HP GlancePlus/UX for s800 11.0
B3701AA C.02.40.000 HP GlancePlus/UX Pak for s800 11.0
PHNE_15591 1.0 LAN product cumulative patch
PHNE_17113 1.0 LAN product cumulative patch

So no patch.

Where can i get that patch from ?

thanks

Not only does it not have the patch, it doesn't have the 100BT software:

J2759BA B.11.00.06 HP-PB 100BT LAN/9000

You need to install that before you can put the patch on!

Thanks Pete. Where do I get the software from?

thanks again.

I'm not sure if you can find it on software.hp.com, but it should be on your 11.0 install disks.

Appreciate your help.

Does anyone know where I can find this software J2759BA B.11.00.06 HP-PB 100BT LAN/9000 ?

Its not on the install CD.

thanks

Is the installation of the software pretty straight forward.
Should I do it on a production server? I dont have a test environment.

It should be very straightforward - absolutely no risk - not even a reboot, I don't think, but you can double check that when you start the install. If it does warn you that there is going to be a reboot, you can always cancel and postpone until an interruption would be more convenient.

The HP-PB 100BT driver is _not_ a DLKM, so there would be a reboot when installing it or its patches.

Don't expect much performance wise from an HP-PB 100BT NIC. Frankly, an HP-PB FDDI NIC crippled with a 1500 byte MTU would be faster and more efficient (although you would need one of those klunky Ethernet-FDDI gateways)

WRT Duplex:

How Autoneg is supposed to work:

When both sides of the link are set to autoneg, they will "negotiate"
the duplex setting and select full duplex if both sides can do
full-duplex.

If one side is hardcoded and not using autoneg, the autoneg process
will "fail" and the side trying to autoneg is required by spec to use
half-duplex mode.

If one side is using half-duplex, and the other is using full-duplex,
sorrow and woe is the usual result.

So, the following table shows what will happen given various settings
on each side:

Auto Half Full

Auto Happiness Lucky Sorrow

Half Lucky Happiness Sorrow

Full Sorrow Sorrow Happiness

Happiness means that there is a good shot of everything going well.
Lucky means that things will likely go well, but not because you did
anything correctly :) Sorrow means that there _will_ be a duplex
mis-match.

When there is a duplex mismatch, on the side running half-duplex you
will see various errors and probably a number of late collisions. On
the side running full-duplex you will see things like FCS errors.
Note that those errors a
