This section describes an example configuration procedure of the network shown in the diagram below.
For the network configuration other than GLS, refer to "3.2.2 Network configuration".
[HOST-A]
1) Setting up the system
1-1) Define IP addresses and hostnames in the /etc/hosts file.
192.168.70.1 host11 # HOST-A Physical IP 192.168.71.1 host12 # HOST-A Physical IP 192.168.80.1 hosta # HOST-A Virtual IP 192.168.70.2 host21 # HOST-B Physical IP 192.168.71.2 host22 # HOST-B Physical IP 192.168.80.2 hostb # HOST-B Virtual IP |
For RHEL8
1-2) Configure the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 BOOTPROTO=none IPADDR=192.168.70.1 PREFIX=24 ONBOOT=yes TYPE=Ethernet |
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=none IPADDR=192.168.71.1 PREFIX=24 ONBOOT=yes TYPE=Ethernet |
For RHEL9
1-2) Set the IP address defined above with the "nmcli connection modify" command.
Configuration of eth0
Set the following parameters with the "nmcli connection modify" command.
ipv4.method: "manual" ipv4.addresses: "192.168.70.1/24" connection.autoconnect: "yes" |
Configuration of eth1
Set the following parameters with the "nmcli connection modify" command.
ipv4.method: "manual" ipv4.addresses: "192.168.71.1/24" connection.autoconnect: "yes" |
After setting, verify that the following parameters are set for ethX with the nmcli connection show command.
connection.type: "802-3-ethernet" connection.id: "ethX" connection.interface-name: "ethX" |
2) Reflecting system setting
Run the following command and reload the connection profile. After reloading the profile, verify eth0 and eth1 are enabled using the ip command.
/usr/bin/nmcli connection reload /usr/bin/nmcli connection up eth0 /usr/bin/nmcli connection up eth1
3) Setting a subnet mask
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0
4) Creating a virtual interface
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m t -i 192.168.80.1 -t eth0,eth1
5) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
[HOST-B]
1) Setting up the system
1-1) Define IP addresses and hostnames in the /etc/hosts file. Defined content is same as HOST-A.
For RHEL8
1-2) Configure the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 BOOTPROTO=none IPADDR=192.168.70.2 PREFIX=24 ONBOOT=yes TYPE=Ethernet |
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=none IPADDR=192.168.71.2 PREFIX=24 ONBOOT=yes TYPE=Ethernet |
For RHEL9
1-2) Set the IP address defined above with the "nmcli connection modify" command.
Configuration of eth0
Set the following parameters with the "nmcli connection modify" command.
ipv4.method: "manual" ipv4.addresses: "192.168.70.2/24" connection.autoconnect: "yes" |
Configuration of eth1
Set the following parameters with the "nmcli connection modify" command.
ipv4.method: "manual" ipv4.addresses: "192.168.71.2/24" connection.autoconnect: "yes" |
After setting, verify that the following parameters are set for ethX with the nmcli connection show command.
connection.type: "802-3-ethernet" connection.id: "ethX" connection.interface-name: "ethX" |
2) Reflecting system setting
Run the following command and reload the connection profile. After reloading the profile, verify eth0 and eth1 are enabled using the ip command.
/usr/bin/nmcli connection reload /usr/bin/nmcli connection up eth0 /usr/bin/nmcli connection up eth1
3) Setting a subnet mask
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0
4) Creating a virtual interface
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m t -i 192.168.80.2 -t eth0,eth1
5) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
