Before changing the setting of GLS in the copy destination system, configure the following setting.
Modifying the /etc/hosts file
Before changing the setting of GLS, start OS in single user mode. After that, change the IP address that is described in the /etc/hosts file to the IP address that is previously specified in "G.1 Designing network of the copy destination system." Change the host name if necessary.
Below is the example when changing the IP address of HOST-A in [Design example 1: Fast switching mode - Single system].
[Before change]
192.168.70.1 host11 # HOST-A Physical IP 192.168.71.1 host12 # HOST-A Physical IP 192.168.80.1 hosta # HOST-A Virtual IP |
[After change]
192.168.170.1 host11 # HOST-A Physical IP 192.168.171.1 host12 # HOST-A Physical IP 192.168.180.1 hosta # HOST-A Virtual IP |
