clues as to why the function/device cannot be added to the pool. For example, Serviceguard might
own the interface:
DETAILED REPORT: Analyzed following hardware paths to detect any
usages in the system:
0/0/0/4/0/0/0 (lan2)
0/0/0/4/0/0/1 (lan3)
DATA CRITICAL RESULTS:
Interface lan2: COMMAND cmnetd PID 2907
Interface lan2: COMMAND cmnetd PID 2907
Service-Guard(SG) Usage:
The interfaces listed below are being used by SG:
lan2
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:
# hpvmdevinfo
Virtual Machine Name Device Type Bus,Device,Target Backing Store Type Host Device Name
Virtual Machine Device Name
==================== =========== ==================== ================== ================

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
