B.4.9 Example of the Cluster system (Mutual standby) without NIC sharing

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".
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 IP1)
192.168.70.2    host11  # HOST-A Physical IP
192.168.70.3    host21  # HOST-B Physical IP
192.168.71.1    hostb   # HOST-A/B Virtual IP (Takeover IP2)
192.168.71.2    host12  # HOST-A Physical IP
192.168.71.3    host22  # HOST-B Physical IP
192.168.70.100  swhub1  # Primary HUB IP
192.168.70.101  swhub2  # Secondary HUB IP
192.168.71.100  swhub3  # Primary HUB IP
192.168.71.101  swhub4  # Secondary HUB IP

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1,2,3) file as follows.

For RHEL7

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

DEVICE=eth0
BOOTPROTO=static
HOTPLUG=no
IPADDR=192.168.70.2
NETMASK=255.255.255.0

ONBOOT=yes
TYPE=Ethernet

For RHEL8 or later

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

BOOTPROTO=none
IPADDR=192.168.71.2
PREFIX=24
DEVICE=eth2
ONBOOT=yes

Contents of /etc/sysconfig/network-scripts/ifcfg-eth3

TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.71.2
PREFIX=24
DEVICE=eth3
ONBOOT=no

2) Reflecting system setting

For RHEL7
Run the following command to reboot the system. After rebooting the system, verify eth0 and eth2 are 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 and eth2 are enabled using the ip command.
```
/usr/bin/nmcli connection reload
```

3) Setting subnet masks

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.71.0 -m 255.255.255.0

4) Creating virtual interfaces

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.1 -e 192.168.70.2 -t eth0,eth1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.71.1 -e 192.168.71.2 -t eth2,eth3

Note

Ensure that the physical IP address specified using option '-e' is the same IP address configured in /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth2. In RHEL8 or later, to correct mismatch of IP addresses, GLS automatically rewrites the configuration of the connection profile based on the IP address specified in the GLS command.

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
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha1 -p 192.168.71.100,192.168.71.101 -b off

6) Setting up the Standby patrol monitoring function

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha2 -m p -t sha0
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha3 -m p -t sha1

7) Creating takeover virtual interfaces

/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
/opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha1

For RHEL7

8) Starting the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll on

9) Starting the Standby patrol monitoring function

/opt/FJSVhanet/usr/sbin/strptl -n sha2
/opt/FJSVhanet/usr/sbin/strptl -n sha3

For RHEL8 or later

8) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now

[Configuration by RMS Wizard]

1) Configuration of userApplication: 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".

2) Starting of userApplication: After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
