Change the IP address of the physical interface of Fast switching mode or GS linkage mode, and change the IP address of the primary physical interface of NIC switching mode to the IP address that is preliminary specified in "G.1 Designing network of the copy destination system." For Virtual NIC mode, this process is not necessary because the IP address is not assigned to the physical interface.
For RHEL8, edit the setting of the physical interface (etc/sysconfig/network-scripts/ifcfg-ethX file), and modify the IP address, netmask, network address, and broadcast address according to the copy destination environment. For RHEL9, edit the setting of the physical interface with the nmcli command. If the default gateway is described, also modify the gateway address according to the copy destination environment.
Below is the example when changing the setting of eth0 in [Design example 1: Fast switching mode - Single system].
/etc/sysconfig/network-scripts/ifcfg-eth0
[Before change]
DEVICE=eth0 BOOTPROTO=static HOTPLUG=no IPADDR=192.168.70.1 NETMASK=255.255.255.0 ONBOOT=yes TYPE=Ethernet |
[After change]
DEVICE=eth0 BOOTPROTO=static HOTPLUG=no IPADDR=192.168.170.1 NETMASK=255.255.255.0 ONBOOT=yes TYPE=Ethernet |
