B.4.7 Example of the Single system without IP address setting of monitoring target

This section describes an example configuration procedure of the network shown in the diagram below.

[HOST-A]

1) Setting up the system

Configure /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
IPADDR=192.168.70.1
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

For RHEL8 or later

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

HWADDR=<MAC address>
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.70.1
PREFIX=24
DEVICE=eth0
ONBOOT=yes

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

HWADDR=<MAC address>
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.70.1
PREFIX=24
DEVICE=eth1
ONBOOT=no

Note

In RHEL8 or later, for the settings (the "/etc/sysconfig/network-scripts/ifcfg-ethX" file) of the physical interfaces bundled by GLS, the definition "HWADDR=<MAC address>" is required.

2) Reflecting system setting

For RHEL7
Run the following command and reboot the system. After rebooting, verify that 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 a subnet mask

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

4) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.10 -e 192.168.70.1 -t eth0,eth1

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p _none_

For RHEL7

6) Activating of virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

7) Starting the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll on

For RHEL8 or later

6) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now

[HOST-B]

1) Setting up the system

Configure /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
IPADDR=192.168.70.2
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

For RHEL8 or later

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

HWADDR=<MAC address>
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.70.2
PREFIX=24
DEVICE=eth0
ONBOOT=yes

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

HWADDR=<MAC address>
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.70.2
PREFIX=24
DEVICE=eth1
ONBOOT=no

Note

In RHEL8 or later, for the settings (the "/etc/sysconfig/network-scripts/ifcfg-ethX" file) of the physical interfaces bundled by GLS, the definition "HWADDR=<MAC address>" is required.

2) Reflecting system setting

For RHEL7
Run the following command and reboot the system. After rebooting, verify that 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 a subnet mask

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

4) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.20 -e 192.168.70.2 -t eth0,eth1

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p _none_

For RHEL7

6) Activating of virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

7) Starting the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll on

For RHEL8 or later

6) Reboot

Run the following command to reboot the system.

/sbin/shutdown -r now
