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.
192.168.80.1 hosta # HOST-A Virtual IP 192.168.101.1 hosta-v1 # HOST-A Virtual IP (Tagged VLAN interface) 192.168.102.1 hosta-v2 # HOST-A Virtual IP (Tagged VLAN interface) 192.168.80.2 hostb # HOST-B Virtual IP 192.168.101.2 hostb-v1 # HOST-B Virtual IP (Tagged VLAN interface) 192.168.102.2 hostb-v2 # HOST-B Virtual IP (Tagged VLAN interface) 192.168.80.100 swhub1 # Primary HUB IP 192.168.80.101 swhub2 # Secondary HUB IP |
1-2) Edit the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.
For RHEL7
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 BOOTPROTO=static HOTPLUG=no ONBOOT=yes DEVICETYPE=hanet |
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=static HOTPLUG=no ONBOOT=yes DEVICETYPE=hanet |

2) Creating a virtual interface
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m v -t eth0,eth1
3) Setting an IP address and a subnet mask
Define an IP address or a subnet mask in the /etc/sysconfig/network-scripts/ifcfg-sha0 file.
For RHEL7
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0
DEVICE=sha0 IPADDR=192.168.80.1 NETMASK=255.255.255.0 BOOTPROTO=static ONBOOT=yes DEVICETYPE=sha HOTPLUG=no |
For RHEL8 or later
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0
DEVICE=sha0 IPADDR=192.168.80.1 PREFIX=24 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet |
4) Setting the network monitoring function
/opt/FJSVhanet/usr/sbin/hanetpathmon target -n sha0 -p 192.168.80.100,192.168.80.101
5) Adding tagged VLAN interfaces
To add tagged VLAN interfaces (sha0.10 and sha0.20) on the virtual interface (sha0), add the following interface setting files:
For RHEL7
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0.10
DEVICE=sha0.10 IPADDR=192.168.101.1 NETMASK=255.255.255.0 BOOTPROTO=static ONBOOT=yes DEVICETYPE=sha VLAN=yes |
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0.20
DEVICE=sha0.20 IPADDR=192.168.102.1 NETMASK=255.255.255.0 BOOTPROTO=static ONBOOT=yes DEVICETYPE=sha VLAN=yes |
For RHEL8 or later
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0.10
VLAN=yes TYPE=Vlan PHYSDEV=sha0 VLAN_ID=10 BOOTPROTO=none IPADDR=192.168.101.1 PREFIX=24 |
Contents of /etc/sysconfig/network-scripts/ifcfg-sha0.20
VLAN=yes TYPE=Vlan PHYSDEV=sha0 VLAN_ID=20 BOOTPROTO=none IPADDR=192.168.102.1 PREFIX=24 |
6) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
6) Setting /etc/NetworkManager/NetworkManager.conf
Describe the tagged VLAN interfaces, which are set in step 5), in /etc/NetworkManager/NetworkManager.conf.
Contents of /etc/NetworkManager/NetworkManager.conf
[main] ... ignore-carrier=sha0.10, sha0.20 |
Note
The setting of /etc/NetworkManager/NetworkManager.conf is required to control the processing of NetworkManager for tagged VLAN interfaces and manage the processing in GLS. Make sure to set /etc/NetworkManager/NetworkManager.conf.
7) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
[HOST-B]
