2 NICS HPUX 11.00 RP5405

[William Richard_1]

Greetings All,
I am trying to bring up the second of three NICS on an RP5405. The card is installed and configured and enabled. The IP address for lan0 is 10.100.0.222 with a subnet of 255.255.255.0. The IP address for lan1 is 10.50.0.222 with a subnet of 255.255.255.0 the default gateways are 10.100.0.0.1 and 10.50.0.1.

ifconfig lan1 reveals the IP of 10.50.0.222 and the subnet of 255.255.255.0

However, when I issue ./net stop ./net start I get the error "Failed to add route entry becuase its interface is not yet initialized. May need add this route entry with a route commad after the interface is up:
add net default: gateway: 10.50.0.1: Network is unreachable."

I have tried commenting (#) out the gateway information in the netconf file but it still is not working. I can ping the address from inside the machine and can ping the gateway 10.50.0.1 from any machine on the network. But I am unable to ping the address 10.50.0.222 from anywhere but the RP5405. Thanks in advance for any help.

Are all of these the same type of card?
If not you also need to configure the appropriate driver file.

Here is the list of them
btlan hpbtlanconf
btlan0 hpeisabtconf
btlan1 hpbasetconf
btlan3 hpbase100conf Internal (core) LAN card
btlan4 hpgsc100conf
btlan5 hppci100conf "external" PCI card A5230A
btlan6 hpsppci100conf V-class PCI lan card
gelan hpgelanconf GigaBit card A4926A

Have a look at this posting for some addtional information.

I think something is wrong. When I ran lanscan -v it shows the three (3) network cards of the system: Core (lan0) btlan5 (lan1) btlan5 (lan2). By your definition these are "external" but they are "internal" ??? I have attached the output of lanscan -v. Any clarification would be appreciated. Regards.

If one of the cards is multi port then the output is normal.

Might want to run ioscan just to see if everything is claimed.

Hi William,

Can you attach the netconf file?

James.

[William Richard]

Yes, everything is claimed in ioscan. The netconf file is attached.

Hi William,

Firstly I would keep the format of the netconf as it was shipped. Maybe I'm going back a bit when I remember problems when this is not so, but for clarity and maintainability it is best to do so (in my opinion).

I think the problem is your are trying to add two default routes. Try adding the route for the 10.50.1 network as:

# route add 255.255.255.0 10.50.0.1 1

You may need to add a "net destination" bit after the add, I can never remember, but I think this is the problem.

Regards,

James.

I tried adding the route manually but I receive the error "add net 255.255.255.0: gateway 10.50.0.1: Network is unreachable"

[William Richard_1]

The cards are single-port

[James Murtagh]

Hi William,

Perhaps try:

# route add net 10.50.0.0 255.255.255.0 10.50.0.1 1

If this doesn't work, possibly use:

# ping -o 10.50.0.1 -n 1

to check the number of hops to the router. If you cabled this up yourself you should be aware of the hop count.

Regards,

James.

[William Richard_1]

That "route" command did not work either. I ran the "ping -o 10.50.0.1 -n 1" and the output is:

10.50.0.2 - [ name lookup failed ]
10.100.0.2 - [ name lookup failed ]
10.100.0.222 - ITS

Indeed, outof the box, one cannot have multiple default routes under HP-UX. Only the first (last?) route add default... route will be used.

Now, if you use ndd to set ip_strong_es_model to one, you may get at least part of the behaviour of multiple default routes. ftp://ftp.cup.hp.com/dist/networking/briefs/annotated_ndd.txt


Per the manpage for the route command:


route(1M) route(1M)

NAME
route - manually manipulate the routing tables

SYNOPSIS
/usr/sbin/route [-f] [-n] [-p pmtu] add [net|host] destination
[netmask mask] gateway [count]

/usr/sbin/route [-f] [-n] delete [net|host] destination
[netmask mask] gateway [count]


if you want to specify a netmask, you need to use the netmask keyword
