B.2.7 Example of the Single system without IP address setting of monitoring target

This section describes an example configuration procedure of the network shown in the diagram below.

[HOST-A]

1) Setting up the system

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

• For RHEL8

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

    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.70.1
    PREFIX=24
    DEVICE=eth0
    ONBOOT=yes

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

    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.70.1
    PREFIX=24
    DEVICE=eth1
    ONBOOT=no

• For RHEL9

  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:"192.168.70.1/24"
    connection.autoconnect:"no"

    After setting, verify that the following parameters are set for ethX with the nmcli connection show command.

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

2) Reflecting system setting

Run the following command and reload the connection profile. After reloading the profile, verify eth0 is enabled using the ip command.

/usr/bin/nmcli connection reload

3) Setting a subnet mask

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0

4) Creating a virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.10 -e 192.168.70.1 -t eth0,eth1

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p _none_

6) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now

[HOST-B]

1) Setting up the system

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

• For RHEL8

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

    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.70.2
    PREFIX=24
    DEVICE=eth0
    ONBOOT=yes

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

    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.70.2
    PREFIX=24
    DEVICE=eth1
    ONBOOT=no

• For RHEL9

  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:"192.168.70.2/24"
    connection.autoconnect:"no"

    After setting, verify that the following parameters are set for ethX with the nmcli connection show command.

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

2) Reflecting system setting

Run the following command and reload the connection profile. After reloading the profile, verify eth0 is enabled using the ip command.

/usr/bin/nmcli connection reload

3) Setting a subnet mask

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0

4) Creating a virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.20 -e 192.168.70.2 -t eth0,eth1

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p _none_

6) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now
