This section describes an example configuration procedure of the network shown in the diagram below. (Network configuration for not enabling physical interface on a standby node.)
For the network configuration other than GLS, refer to "3.2.2 Network configuration".
For configuring the cluster system, refer to the Cluster system manual.
In this section, description of private LAN is omitted.
The dotted line indicates that the interface is inactive.
[HOST-A]
1) Setting up the system
1-1) Define IP addresses and hostnames in /etc/hosts file.
192.168.70.1 hosta # HOST-A/B Virtual IP (Takeover IP address) 192.168.70.100 swhub1 # Primary HUB IP 192.168.70.101 swhub2 # Secondary HUB IP |
For RHEL8
1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0, 1) file as follows.
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet IPADDR=192.168.70.1 PREFIX=24 DEVICE=eth0 ONBOOT=no |
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet IPADDR=192.168.70.1 PREFIX=24 DEVICE=eth1 ONBOOT=no |
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:"no" |
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. 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) 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 e -i 192.168.70.1 -t eth0,eth1
5) Setting up the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101 -b off
6) Setting up the Standby patrol monitoring function
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -t sha0
7) Creating a takeover virtual interface
/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
8) 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 /etc/hosts file. Defined content is same as HOST-A.
For RHEL8
1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0, 1) file as follows.
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet IPADDR=192.168.70.1 PREFIX=24 DEVICE=eth0 ONBOOT=no |
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet IPADDR=192.168.70.1 PREFIX=24 DEVICE=eth1 ONBOOT=no |
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:"no" |
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. 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) 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 e -i 192.168.70.1 -t eth0,eth1
5) Setting up the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101 -b off
6) Setting up the Standby patrol monitoring function
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -t sha0
7) Creating a takeover virtual interface
/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
8) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
[Configuration by RMS Wizard]
After configuring HOST-A and HOST-B, register the created takeover virtual interface as a Gls resource to create a cluster application. Use RMS Wizard to set up the cluster configuration. For details, see "PRIMECLUSTER Installation and Administration Guide".
After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
