Configuring a second NIC / lan card

[David Preston_4]

I added a second network card to my server over the weekend to interface with a router on a seperate network, If I do an IO scan it shows the card as unknown, but shows the description. What functions, or files do I need to update for the system to see this card and path? I am looking through my network classes and haven't found it yet.

Thanks in advance
Dave

Hi David,

What is your card model no and hp part no?

Hi:

The most common cause for this is that you have added another type of card but have not yet installed the driver software for the new card which is almost always located on Disk 1 of any Applications Software Bundle.

[Duncan Edmonstone]

You need to install the drivers for your network card. Most of these will be located on the first applications CD. If you know how to use swinstall all should be plain sailing.

I'm afraid it will also require a reboot!

It just needs a driver to be installed. Let us know the model and the type of the card you installed. It would be more helpful if you can look at the part number on the card.

Card J2146A
Also card is blinking , self-test fail

is that also driver related, or a bad card?

I think this is a BNC cum AUI-TP network card. If it is flashing, then you may have to remove the card and set the internal switch to AUI. You also will have J2146A software on Application CD-1. Install it once you changed the internal jumper on the card.

I have a j2146a flashing led, what does this mean?

Configuration Info

Operating System - HP-UX
Version -
Hardware System - HP 9000
Series -K400

Solution

At powerup led flashes during selftest, and turns off if tests pass,
it turns on solid if tests fail. After passing selftest, the lan card
sends a packet out to the network. If it is OK, the led stays off. If
it fails, the led flashes.

Possible causes of flashing led are as follows:
- Jumper set wrong, external selects aui, internal selects bnc thinlan.
- Bad network cabling or termination
- Blown fuse on j2146a
- No heartbeat supplied by transceiver, enable SQE test and Link Beat
additional information lan3 driver.

landiag will show current status.

So, you would need to remove the card. Reset the setting. Reinstall it; and then install the HP-PB driver software for the lan card.

Hi David,

enable "lanmux0" driver in the kernel to use this controller card. If it still does not work. check the jumper settings on the card. You should set it to BNC if you are using BNC cable or to AUI if you are using a AUI / AUI-TP connection. To change the jumper settings you have to remove the card from the system. don't be worried abt the flashing led. It does so on this card. I have this card on k-class and the led's are flashing. The card is still working.

Hope this helps.

OK let me see If I have this right,
1) remove card and check for jumper setting BNC/AUI
I assume this is evident on the card?
2) load driver lanmux0 into kernal (I found this in sam)
load kernal and reboot
3) one of you also mentioned that I need to get the driver for this card from the application CD, but I dont find it on cd1 of the applications, that number is not on the list.

Am I on the right track?

Hi David,

Just reconfigure the kernel first after adding "lanmux0" into the kernel. Reboot the system and then try the lan card connection. If that does not work, remove the card and check the jumper settings. If you are using a AUI-TP Converter, you may have to check the switch settings on that too. But first, just reconfigure the kernel and try.

Hope this helps.

OK I am almost there, I changec the jumper, reseated the card, loaded the lanmux0 driver into the kernal and now I see link lights on the transciever and router, but I am missing the device files on the server. ioscan see the device as claimed , but there are no /dev files

# ioscan -fnC lanmux

Hi David,

Man insf. Look at the -H option.

Hi David,

"ifconfig lanmux0" will return the message "ifconfig: no such interface". Do a "ioscan -fn" and check for the next line after lanmux0 in the output. You'll find something like /dev/diag/lan0 /dev/lan0 "or" /dev/diag/lan1 /dev/lan1 . This is the interface you should use with ifconfig. If the line reads lan0, do "ifconfig lan0".

Hope this helps.

as shown earlier the card shows in ioscan at 10/4/16 and a blank line shows at 10/4/16.1
ioscan -fnC lanmux shows the card, driver and claimed, but I can not get a device file to create. insf returns nothing in any format, mksf returns the messave "couldnt find driver matching argument" with any arguments.

in sam under cards, the option create device files says it's complete and to look at show device files but there is nothing there.
