When cloning the system of NIC switching mode, the following IP addresses must be changed on the copy destination system.
Virtual interface
Physical interface
Monitoring destination IP of the HUB monitoring function (when the destination HUB is different)
Takeover virtual interface (for cluster system)
Before cloning the system, see the following examples to decide the IP address to be assigned to the copy destination system. Check the IP address of the router on the destination network in advance as well when the copy destination system is connected to the network different from the network on the copy source system.
Below is the design example of how to clone HOST-A of "B.4.1 Example of the Single system without NIC sharing" in the RHEL7 environment.
As well as for eth0, decide the IP address for eth1 in advance in the RHEL8 environment.
IP address to be changed | Value in copy source | Value in copy destination | ||
|---|---|---|---|---|
HOST-A | Logical IP address | sha0/ eth0 | 192.168.70.1 | 192.168.170.1 |
Physical IP address | 192.168.70.2 | 192.168.170.2 | ||
HUB | 192.168.70.100 192.168.70.101 | 192.168.170.100 192.168.170.101 | ||
Below is the design example of how to clone HOST-A and HOST-B of "B.4.8 Example of the Cluster system (1:1 Standby)" in the RHEL7 environment.
As well as for eth0, decide the IP address for eth1 in advance in the RHEL8 environment.
IP address to be changed | Value in copy source | Value in copy destination | ||
|---|---|---|---|---|
HOST-A | Logical IP address | sha0/ eth0 | 192.168.70.1 | 192.168.170.1 |
Physical IP address | 192.168.70.2 | 192.168.170.2 | ||
HUB | 192.168.70.100 192.168.70.101 | 192.168.170.100 192.168.170.101 | ||
HOST-B | Logical IP address | sha0/ eth0 | 192.168.70.1 | 192.168.170.1 |
Physical IP address | 192.168.70.3 | 192.168.170.3 | ||
HUB | 192.168.70.100 192.168.70.101 | 192.168.170.100 192.168.170.101 | ||
Takeover virtual interface | sha0:65 | 192.168.70.1 | 192.168.170.1 | |
