VLAN-Backed vswitches
To enable the VLAN-backed vswitch (VBVsw) feature, PHNE_40215 or a superseding patch is
required to be installed on the VSP. This patch is available as an individual patch or as part of
"FEATURE11i" bundle. To verify that the patch is installed, enter the following:
# swlist -l product | grep PHNE_40215
PHNE_40215 1.0 LAN cumulative patch
The dlpi_max_ub_promisc kernel tunable must be set to when using a VBVsw type vswitch.
Otherwise, attempting to boot the vswitch fails with the following error message from the hpvmnet
command:
# hpvmnet -b -S vs5000
hpvmnetd: setup_downlink: promisc failed, recv_ack:
promisc_phys: UNIX error - Device busy, errno 5
To set the kernel tunable, enter the following:
# kctune dlpi_max_ub_promisc=16
Miscellaneous AVIO Networking problems
The following are the other AVIO networking problems:
• If you modify the MAC address of an interface in the guest, the hpvmstatus command in
the VSP does not display the current MAC address correctly. There is no fix or workaround
for this problem at this time.
• Just as with physical devices on a network, for communication to occur uninterrupted between
all stations on a LAN segment, the MTUs of all the systems on the LAN segment or VLAN must
match, whether they are physical systems or guests. The VSP does not check for MTU
mismatches for its guests.
• The lanadmin card specific options that are supported on igssn on the guest are:
-x:speed,fctrl,cko,type,card_info,stats drv,vmtu,and drv_pr.◦
◦ -X:drv_pr_on,drv_pr_off,and stats clear
A.3.2 Troubleshooting DIO
If you are unable to add a DIO function or device to the DIO pool that is not in use by the VSP or
already in the DIO pool, check the CRA log file /var/adm/cra.log. When hpvmhwmgmt -p
dio –a … is executed, a Critical Resources Analysis (CRA) Report is generated and might provide
clues as to why the function or 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
