unable to configure LAN card for rx4640

[Annelise Wilken]

I have an rx4640 HP Integrity server that came with a dual port LAN card installed.

ioscan -fnC lan produces following:

lan0 0/1/2/0 Claimed HP AB352-60001 PCI/PCI-X 1000BASE-T Dual-Port Core
lan1 0/1/2/1 Claimed HP AB352-60001 PCI/PCI-X 1000BASE-T Dual-Port Core

lanscan shows interfaces UP

In SAM I've disabled lan0 and tried pinging various IPs from the command line but no lights are flashing on the card.

I've moved the cable to the other port on the card and tried pinging but nothing happens.

lan1 is set to autoneg with full duplex mode and netmask of 255.255.255.0

In /etc/rc.config.d/netconf I've checked that lan0 is down and lan1 is up, the index numbers are correct (i.e all 0 for lan 0 and 1's for lan1)

I've added a route to the gateway:

route add default 172.31.2.3

when I run lanadmin for each interface they show:

Administration Status UP
Operation Status Down

not sure what else to do????

Can anyone help,

Many thanks

Although I am not familiar with rx4640 machine at all, something sounded fishy here.

you have a PCI card with dual GBIT interfaces on it. And also this server has a built in LAN connection on the chasis. And on your ioscan you can only see lan0 (presumably builtin interface) and a lan1 and that's it ? What happened to the second LAN port on that card ?

anyway, under these circumstances, let's start with the usual. What does

ifconfig lan0
ifconfig lan1

commands show you as output ?

[Stephen Keane]

ifconfig lan0 plumb
ifconfig lan1 plumb

[Annelise Wilken]

I tried the follwoing:

ifconfig lan0 plumb
ifconfig lan1 plumb

but still can't ping anything ..... anyone any other ideas???

one more time :

What does

ifconfig lan0
ifconfig lan1

commands show you as output ?

[Duncan Edmonstone]

What's at the other end of your LAN cable? Are you sure that is setup OK? Is it a GbE port or just 100BT? Is your site using VLANs?

Don't automatically assume the problem is with the server...

ifconfig lan0 up
ifconfig lan1 up

Actually, the "core" I/O in an rx4640 is really just a PCI card installed in either slot 1 or 2. As such, it is entirely possible that someone may have only the two ports of a dual-port GbE NIC showing in ioscan. This is further supported (although not conclusively) by their being named lan0 and lan1.

As for pinging and such, it would be best to determin link-level connectivity first via linkloop (man linkloop). If you have no other HP-UX systems in the same broadcast domain (reachable going only through switches not routers) there is a port of linkloop to linux - i think it is on sourceforge.net - anyway a search for "linkloop linux" should find it.

Once you have determined that the ports are working at the data-link (ie layer-2 or "ethernet" layer in this case) then we can see about making sure that your IP addresses are set correctly and all - for example, if you have tried to ifconfig both of them into the same IP subnet, but don't have both of them connected to the same switch (ie have equal connectivity to the rest of the network) then there can be problems with not seeing traffic.

It is best to have separate physical ports configured into separate IP subnets. Ifyou want load balancing or failover you should purchase and install the Auto Port Aggregation software. Otherwise, there will be a bit of scripting in your future :)

I suggest that you go into "sam" and check your name switch service order. An easy way to set up networking on lan0 is to run "set_parms initial".

[Annelise Wilken]

You were correct - why blame the server!! I hadn't been patched to the correct switch ....doh!!!!

Many thanks all.
