Adding a Virtual IP Address

Download the SAP S/4HANA (1809) installation package to the shared directory /sapcd and perform the installation.

If you use the SAP ASCS HA script provided by HUAWEI CLOUD, the virtual IP address is automatically configured in the installation script. Before installing SAP ASCS and ERS, you need to manually add the virtual IP addresses of ASCS and ERS on the active and standby nodes.

Command for adding virtual IP address on the active node:

ip addr add <ASCS VIP>/24 broadcast dev eth0:0

Example: ip addr add 172.16.0.12/24 broadcast 172.16.0.255 dev eth0:0

Command for adding virtual IP address on the standby node:

ip addr add <ERS VIP>/24 broadcast dev eth0:1

Example: ip addr add 172.16.0.13/24 broadcast 172.16.0.255 dev eth0:1
