Use the hvmdevinfo command to display the hardware device mapping between vPar/VM and
the VSP. You can run this command on the VSP or the vPar/VM:
VSP:

10.6 Troubleshooting network problems
This section describes some commonly encountered problems using virtual networks.
• Do not kill hpvmnetd
Do not use the kill command to remove the hpvmnetd process. If you do, the following
error message indicates that the hpvmnet daemon has been killed:
hpvmnetd: Switch 0000564d4c414e31 already exists
If the hpvmnetd process is removed, vswitches do not work properly.
• AVIO LAN devices not claimed by guest with DOWN vswitch at boot time.
In addition to running ioscan, you must re-run the necessary network startup scripts, so that
IP addresses can be reconfigured on the network interface cards (NICs). For example:
/sbin/rc2.d/S340net start
/sbin/rc2.d/S340net-ipv6 start
10.6.1 Redefining pNICs for HP-UX guests
Changing the hardware address of a vswitch has the same effect as moving a network adapter
from one hardware slot to another on an HP Integrity system. Similar to other HP-UX systems, the
guest file /etc/rc.config.d/netconf must be modified so that INTERFACE_NAME[0] reflects
the new LAN PPA assigned by the HP-UX network driver on the first guest reboot after the
modification. At this first reboot, the LAN interfaces configuration fails, as follows:
