I recently purchased a refurbished HP 9000 with HPUX 10.20.   After initial setup.... it's not recognizing the lan interface.   All attempts to check the status or configure it says, no interface is found. (ifconfig, netstat,

How do I create a new lan interface for the network card in 10.20?  

Thanks

Does `ioscan -fn` show the lan interface? If not, you will need to add the drivers into the kernel
Does `lanscan` detect the interface?

Both commands do not show the lan interface.

landiag.... returns "Unable to open device file /dev/dlpi

all other lan commands show no lan interface.

so how do I add it to the kernel?

Any help is appreciated.

I'm guessing the system was built before the network card was added, otherwise the drivers and device files would have been created.

Please post the output of `ioscan -fn |egrep "unknown|lan"`  If the network card is not faulty, it will show up here as an unknown device type, but will show a Description; From this, we can work out what kernel drivers need to be added.

Also post the output of `swlist -v |grep Network` to see if any Network packages have been loaded. You will probably need a set of HP-UX 10.20 media if they haven't

The results of ioscan -fn ....
unknown     -1    8/0      UNCLAIMED UNKNOWN GSC-TO-PCI BUS BRIDGE
unknown     -1    8/16/5.3.0   UNCLAIMED UNKNOWN    HP C1537A


The results of swlist -v are ...

blank?   It's returning nothing?  even if I exclude the grep.

Very strange.

The HP C1537A is a DDS3 tape drive, but that's not important right now...

`swlist ` not returning anything indicates that "swagent" isn't working - and swagent wants a working network (or dummy network)

As ioscan doesn't detect a lan device (or unknown device that looks like a LAN card), that indicates the LAN card is faulty; Does it show any LEDs? (e.g. power/fault/network - it depends on the card type. Can you read the card type off the back of the card?).

I'd try reseating the card or trying it in another slot, but you may need a replacement
