HP9000 : Is it possible to set up an HP9000 running HP-UX 11.0 as a multi-homed host?
Posted on 2004-11-23
I have an HP9000 K420 box running HP-UX 11.0. The standard NIC that comes with this box is a 10-baseT variety. I recently added a card to the server, which has two 100-baseT ports, with the idea of spreading my network traffic over multiple NICs. I need all three NICs to be on the same sub-net and I don't know if that's possible.
After installing the hardware, I added the two new NICs to the system via 'sam'. The only prompt that I got during this process was that an alias was required, which I entered. Both 100-baseT NIC showed as 'enabled' on the 'sam' screen, along with the 10-baseT NIC. At this point, all of my network traffice to the 10-baseT NIC was functional. The following three lines are now in /etc/hosts :
10.0.1.230 araphp lan10bt1 (this was the original line prior to the addition of the new NICs)
10.0.1.231 araphp lan100bt1
10.0.1.232 araphp lan100bt2
At this point, I stopped for the day. My system reboots each night in preparation for a backup. The following day, after the reboot,
I had no connectivity to my 10-baseT NIC. No cables had been moved. No settings changed, at least on my part. I went into 'sam' and disabled the two 100-baseT NICs and my connectivity began working on my 10-baseT NIC, again. I then re-enabled the two 100-baseT NICs. However, I did not connect them to the network. They were simply enabled. Following morning, same problem.
Is there a setting that I am missing? Do I need to run any additional services to make this work? Can all three NICs reside on the same sub-net?
I would appreciate any help that you can provide.
