Network Config conflect problem. Maybe?

[Marty Metras]

I'm confused.
When we rebooted our HP-9000 with HP-UX 11.0 the other day after adding a JBOD, the system hung on the LAN causing it to take forever to come up. Thinking it was a bad NIC that just happened to fail, we removed it and it was fine.
The new NIC did the same thing.
Here is what I found that is confusing.
With only the one NIC (looking in sam)
LAN0 shows 192.168.1.5
LAN0:1 shows 192.168.1.10
This is what I think it should be.
With the second NIC installed (looking in sam)
LAN0 shows 192.168.1.5
LAN0:1 shows 0.0.0.0
LAN0 shows 192.168.1.10
LAN0:1 shows 0.0.0.0
But the system hangs on boot an you can not ping the box.
========================
Now I have the box up with only NIC. I can not down it because Production needs it.
========================
Here is what I found in /etc/rc.config.d/netconf
IP_ADDRESS[0]=192.168.1.5
SUBNET_MASK[0]=255.255.0.0
BROADCAST_ADDRESS[0]=192.168.255.255
INTERFACE_STATE[0]=up
DHCP_ENABLE[0]=0

IP_ADDRESS[1]=192.168.1.10
SUBNET_MASK[1]=255.255.0.0
INTERFACE_NAME[1]=lan1
BROADCAST_ADDRESS[1]=192.168.255.255
INTERFACE_STATE[1]=up
DHCP_ENABLE[1]=0
IP_ADDRESS[2]=192.168.1.10
SUBNET_MASK[2]=255.255.0.0
INTERFACE_NAME[2]=lan0:1
BROADCAST_ADDRESS[2]=192.168.255.255
INTERFACE_STATE[2]=up

I'm thinking this may be the cause. Not sure.
I think this is telling me that there is the same IP address on 2 cards and when I remove LAN1 then LAN0:1 uses the .10 else when both NICs are installed it tries to asign the same IP to both causing the lan to fail.

I think the fix would to remove the settings for LAN1 in /etc/rc.config.d/netconf
Then reset as needed after the NIC is reinstalled.

Can you help me clear this up?
Is there any other Config files I should look at?

IP_ADDRESS[1]=192.168.1.10
SUBNET_MASK[1]=255.255.0.0
INTERFACE_NAME[1]=lan1
BROADCAST_ADDRESS[1]=192.168.255.255
INTERFACE_STATE[1]=up
DHCP_ENABLE[1]=0
IP_ADDRESS[2]=192.168.1.10
SUBNET_MASK[2]=255.255.0.0
INTERFACE_NAME[2]=lan0:1


Two interfaces with the same ip address. Virtual or not this an unsupported configuration.

Steven,
I'm less confuesed now.
I'll remove it and go on from there.

Thanks,
Marty
