Managing Serviceguard Extension for SAP on Linux (IA64 Integrity and x86_64), April 2009

Add IPv6 addresses to /etc/hosts an all cluster nodes.
The following virtual and physical addresses will be used for this IPv6 configuration.
vi /etc/hosts
2001::101:51 sap51 # vip ascsSX1 – ABAP SCS
2001::101:53 sap53 # vip D00SX1 - CI
2001::101:54 sap54 # vip D01SX1 – DIALOG
2001::101:146 sap146 # phys node1 - CLUSTER
2001::101:147 sap147 # phys node2 – CLUSTER
16.41.101.51 sap51 # vip ascsSX1
16.41.101.53 sap53 # vip D00SX1
16.41.101.54 sap54 # vip D01SX1
16.41.101.146 sap146 # phys node1 - CLUSTER
16.41.101.147 sap147 # phys node2 – CLUSTER
Installation Step: IP1220
The followings steps show how to enable IPv6 for a RHEL node.
In this example IPv6 address 2001::101:147/24 will be used for this node.
First edit and set NETWORKING_IPV6=yes in the following file:
vi /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
IPV6FORWARDING=no
IPV6_AUTOCONF=no
IPV6_AUTOTUNNEL=no
HOSTNAME=sap147
GATEWAY=16.41.101.1
Edit and set IPV6ADDR=2001::101:147/24 in the following file:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
BROADCAST=16.41.101.255
HWADDR=00:12:79:94:D4:C8
IPADDR=16.41.101.147
NETMASK=255.255.255.0
NETWORK=16.41.101.0
ONBOOT=yes
IPV6INIT=yes
IPV6ADDR=2001::101:147/24
IPV6_MTU=1280
Restart the network interface with the following command:
service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
