This section describes a configuration setup example for the following network configuration.
1) Setting up the system
1-1) Define the IP addresses and host names you use in the /etc/hosts file.
192.168.80.1 hosta # virtual IP address of the KVM host 192.168.80.100 swhub1 # IP address of the primary monitoring destination's HUB 192.168.80.101 swhub2 # IP address of the secondary monitoring destination's HUB |
For RHEL8
1-2) Edit the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0, 1) files 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 the virtual bridge
For RHEL8
Create /etc/sysconfig/network-scripts/ifcfg-br0 as a new interface setup file for the virtual bridge.
Contents of /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0 TYPE=Bridge BOOTPROTO=none IPADDR=192.168.80.1 PREFIX=24 ONBOOT=yes DELAY=0 |
For RHEL9
Create br0 with the following parameters by using the "nmcli connection add" command.
connection.id: "br0" connection.interface-name: "br0" connection.type: "bridge" connection.autoconnect: "yes" ipv4.method: "manual" ipv4.addresses: "192.168.80.1/24" |
4) Setting a virtual interface
For RHEL8
Define the virtual bridge name (BRIDGE=br0) of the connection target in the /etc/sysconfig/network-scripts/ifcfg-sha0 file. In addition, delete the statements related to the IP address ("IPADDR" and "PREFIX").
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0
DEVICE=sha0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
BRIDGE=br0 |
For RHEL9
Set the following parameters to sha0 with the "nmcli connection modify" command.
connection.slave-type: "bridge" connection.master: "br0" ipv4.method: "disabled" |
5) Setting the network monitoring function
/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p 192.168.80.100,192.168.80.101
6) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
