This section describes a configuration setup example for the following network configuration.
Note
Set so that the network error detection time of GLS on the guest OS becomes longer than the network error detection time by the redundant function on the VMware host.
[Setting up the VMware host]
Connect the redundant interface to the guest machine on the VMware host machine.
[Setting up the guest OS1]
1) Setting up the system
1-1) Define the IP addresses and hostnames in /etc/hosts file.
192.168.70.10 hosta # guest OS1/2 Virtual IP (Takeover IP address) 192.168.70.1 host11 # guest OS1 Physical IP 192.168.70.2 host21 # guest OS2 Physical IP 192.168.70.100 swhub1 # Primary HUB IP 192.168.70.101 swhub2 # Secondary HUB IP |
1-2) Assign the defined IP address stated above in /etc/sysconfig/network-scripts/ifcfg-eth0 file.
For RHEL7
DEVICE=eth0 BOOTPROTO=static HOTPLUG=no IPADDR=192.168.70.1 NETMASK=255.255.255.0 ONBOOT=yes TYPE=Ethernet |
For RHEL8 or later
TYPE=Ethernet BOOTPROTO=none IPADDR=192.168.70.1 PREFIX=24 DEVICE=eth0 ONBOOT=yes |
2) Reflecting system setting
For RHEL7
Run the following command and reboot the system. After rebooting the system, verify eth0 is enabled using the ip command.
/sbin/shutdown -r now
For RHEL8 or later
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 up the subnet mask
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0
4) Creating the virtual interface
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.10 -e 192.168.70.1 -t eth0
5) Setting up the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101
6) Creating the takeover virtual interface
/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
7) Starting the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll on
7) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
[Setting up the guest OS2]
1) Setting up the system
1-1) Define the IP address and host name to be used in /etc/hosts file. The defined content is the same with guest OS1.
1-2) Assign the defined IP address stated above to /etc/sysconfig/network-scripts/ifcfg-eth0 file.
For RHEL7
DEVICE=eth0 BOOTPROTO=static HOTPLUG=no IPADDR=192.168.70.2 NETMASK=255.255.255.0 ONBOOT=yes TYPE=Ethernet |
For RHEL8 or later
TYPE=Ethernet BOOTPROTO=none IPADDR=192.168.70.2 PREFIX=24 DEVICE=eth0 ONBOOT=yes |
2) Reflecting system setting
For RHEL7
Run the following command and reboot the system. After rebooting the system, verify eth0 is enabled using the ip command.
/sbin/shutdown -r now
For RHEL8 or later
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 up the subnet mask
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0
4) Creating the virtual interface
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.10 -e 192.168.70.2 -t eth0
5) Setting up the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101
6) Creating the takeover virtual interface
/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
7) Starting the HUB monitoring function
/opt/FJSVhanet/usr/sbin/hanetpoll on
7) Reboot
Run the following command to reboot the system.
/sbin/shutdown -r now
[Setting up the RMS Wizard]
1) Setting up the cluster environment
After the setup of guest OS1 and guest OS2 is completed, register the created takeover virtual interface as a Gls resource to create cluster application. The setting up of cluster environment is performed using RMS Wizard. For details, see "PRIMECLUSTER Installation and Administration Guide."
2) Starting the cluster application
After the setup of cluster environment is completed, the takeover virtual interface is activated in the guest OS1 by starting the cluster application.
