Full Discussion: Virtual Ethernet VIO HMC LPARs

The trunk priority is not important on the LPAR but is on a dual VIO configuration. Also the access external network MUST NOT be selected on the LPAR as there is no external network to access as it is all logical!
I have removed the Trunk priority and access to external network from the LPARs... and it is working fine.

I am facing another issue.

I would like to create another Virtual Ethernet Adapter and give it a new IP - different segment and different subnet mask..

LPAR 1
My en0 ==> 172.16.101.10
G/W ==> 172.16.101.1
Subnet mask: 255.255.255.0
VLAN ID: 1
IEEE.8 = NO


For my en1 ==> 10.10.10.10
G/W -- No gateway since it is connected to the same switch as above (Cisco Switch) but this IP is going to be used between LPARs only for RAC ( Oracle Real Application Cluster )
VLAN ID: 1
IEEE.8 = NO
subnet mask: 255.255.255.252

LPAR 2

My en0 ==> 172.16.101.11
G/W ==> 172.16.101.1
Subnet mask: 255.255.255.0
VLAN ID: 1
IEEE.8 = NO


For my en1 ==> 10.10.10.11
G/W = No Gateway
VLAN ID: 1
IEEE.8 = NO
subnet mask: 255.255.255.252

MY VIO Server 1
physical Port ==> en1 ==> 172.16.101.2
G/W: 172.16.101.1
VLAN ID: 1
IEEE.8 = NO
Subnet mask: 255.255.255.0

Physical Port
virtual en3 ( mapped with en0 for external ) ==> 172.16.101.3
G/W: 172.16.101.1
VLAN ID: 1
IEEE.8 = NO
Subnet mask: 255.255.255.0

MY VIO Server 2
physical Port ==> en1 ==> 172.16.101.4
G/W: 172.16.101.1
Subnet mask: 255.255.255.0

Physical Port
virtual en3 (mapped with en0 for external) ==> 172.16.101.5
G/W: 172.16.101.1
Subnet mask: 255.255.255.0


But I cannot ping
from LPAR1 to LPAR2 on the IP 10.10.10.11

1) Do I need to add a different VLAN ID in each LPAR for 10.10.10.x SUB-NET ?

2) Do I need to add a different VLAN ID and create a virtual ethernet adapter in VIO_Server ?

3) Do I need to enable the IEEE8 ?

any help would be appreciated.

I.e. there is no client LPAR using the VIO VG. Yet when I try to reducevg the VIO VG, it complains that the LV hosted on the PV is... (2 Replies)

PCN(4)							   BSD Kernel Interfaces Manual 						    PCN(4)

NAME

     pcn -- AMD PCnet-PCI Ethernet family driver

SYNOPSIS

     pcn* at pci? dev ? function ?

     Configuration of PHYs may also be necessary.  See mii(4).

DESCRIPTION

     The pcn device driver supports Ethernet interfaces based on the AMD PCnet-PCI family of Ethernet chips.  The chips supported by the pcn
     driver include:

     o	 Am79c970 PCnet-PCI Single-Chip Ethernet Controller for PCI Local Bus

     o	 Am79c970A PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller for PCI Local Bus

     o	 Am79c971 PCnet-FAST Single-Chip Full-Duplex 10/100Mbps Ethernet Controller for PCI Local Bus

     o	 Am79c972 PCnet-FAST+ Enhanced 10/100Mbps PCI Ethernet Controller with OnNow Support

     o	 Am79c973/Am79c975 PCnet-FAST III Single-Chip 10/100Mbps PCI Ethernet Controller with Integrated PHY

     PCnet-PCI chips are found on some Hewlett-Packard PCI Ethernet boards, and on the Allied Telesyn AT-2700TX PCI Ethernet board.  They are also
     found on some processor evaluation boards as an example peripheral.

     The pcn driver also supports the emulated PCnet-PCI interface provided by VMware.

SEE ALSO
