B.4.1 Example of the Single system

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.

fc00:80::1       v6hosta         # HOST-A Virtual IP
fc00:80::2       v6hostb         # HOST-B Virtual IP
fe80::xx:1       swhub1          # Primary HUB IP
fe80::xx:2       swhub2          # Secondary HUB IP

• For RHEL8

  1-2) Edit the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0, 1) file as follows.

  • Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

    TYPE=Ethernet
    BOOTPROTO=none
    DEVICE=eth0
    ONBOOT=yes

  • Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

    TYPE=Ethernet
    BOOTPROTO=none
    DEVICE=eth1
    ONBOOT=yes

• For RHEL9

  1-2) Set the following parameters to ethX (X is 0, 1) with the "nmcli connection modify" command.

  ipv4.method: "disabled"
  ipv6.method: "disabled"
  connection.autoconnect: "yes"

  After setting, verify that the following parameters are set for ethX with the "nmcli connection show" command. If the parameters are different, fix the settings seeing "3.2.2.1 Setup common to modes."

  connection.type: "802-3-ethernet"
  connection.id: "ethX"
  connection.interface-name: "ethX"

2) Creating a virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m v -t eth0,eth1

3) Setting an IP address

• For RHEL8

  Define an IP address or other entries in the /etc/sysconfig/network-scripts/ifcfg-sha0 file.

  • Contents of /etc/sysconfig/network-scripts/ifcfg-sha0

    DEVICE=sha0
    IPV6INIT=yes
    IPV6ADDR=fc00:80::1/64
    BOOTPROTO=none
    ONBOOT=yes
    TYPE=Ethernet

• For RHEL9

  Set the following parameters to sha0 with the "nmcli connection modify" command.

  ipv6.method: "manual"
  ipv6.addresses: "fc00:80::1/64"

4) Setting the network monitoring function

/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p fe80::xx:1,fe80::xx:2

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.

1-2) Edit ethX (X is 0, 1). Defined content is same as HOST-A.

2) Creating a virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m v -t eth0,eth1 

3) Setting an IP address

• For RHEL8

  Define an IP address or other entries in the /etc/sysconfig/network-scripts/ifcfg-sha0 file.

  • Contents of /etc/sysconfig/network-scripts/ifcfg-sha0

    DEVICE=sha0
    IPV6INIT=yes
    IPV6ADDR=fc00:80::2/64
    BOOTPROTO=none
    ONBOOT=yes
    TYPE=Ethernet

• For RHEL9

  Set the following parameters to sha0 with the "nmcli connection modify" command.

  ipv6.method: "manual"
  ipv6.addresses: "fc00:80::2/64"

4) Setting the network monitoring function

/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p fe80::xx:1,fe80::xx:2

5) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now
