I have an APA (AutoPort Aggregation) network environment on my HP-UX servers. Our Security Unit has requested that we no longer allow Service port (server to server) comnmunication for our applications and implement IP communication (server to switch) for the applications.
That would require slicing a NIC into dozens of IPs so the developers and testers can be sorted into application groups by unique hostname instead of assigning each developer and tester a unique service port.
Everyone seems to be using the same terminology for very different purposes.
APA is a "Multi-homing" product that "trunks" multiple physical NICs together into a load balancing and failover "Link Aggregate".
Some refer to this "trunk" as a Virtual NIC or IP (confusing).
The act of slicing a physical NIC into multiple virtual IPs is often refered to as "Multi-homing" as well (confusing).
These two processes appear to be sharing terminology, yet they are very different.
I tried and failed to slice an APA link aggregate (LA) into a second virtual NIC using ifconfig.
ifconfig lan900:1 [IP address] netmask [mask] up
It simply broke the network. I had to recycle the interface.
I tried and failed to configure additional LAs using the existing physical NICs that comprise lan900.
I tried using SAM and by editing /etc/rc.config.d/netconf
netconf doesn't seem to know anything about APA
Apparently, you can't reuse NICs for new LAs.
Is there any way to slice an APA LA into multiple virtual NICs?
Solved! Go to Solution.

Can you type here what is the command you are using, what are the command outputs? And what do you mean it broke the network?
Can you also send the output of:
# nwmgr --get -S apa
and conf files:
/etc/rc.config.d/netconf
/etc/rc.config.d/hp_apaconf
/etc/rc.config.d/hp_apaportconf

Re: Multi-homed NICs versus Virtual IPs
The instant I hit the enter key for the above command, my terminal connection was severed. I didn't even get a carriage return.
I had to access the console and reset the lan900 interface using ifconfig.
I am unfamilar with "nwmgr". I have 18 HP-UX 11.11 and 11.23 servers. None of them have nwmgr. I assume this is an 11.31 utility.
I typically use lanscan -q:
900 0 1
901
902
903
904
