15.7.1 Initial GLS Setup

When using GLS, execute the initial GLS setup to the network used for the administrative LAN and the public LAN, according to the procedure below. Also, execute the initial GLS setup to the network for a storage and the network used for the cluster interconnect. For details on each setting, refer to "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function."

Set the following in each node building the cluster.

The following is the procedure to duplicate eth0, eth1 that are used in the network of the public LAN and the administrative LAN, and to duplicate eth2, eth3 that are used in the network for a storage and the network of the interconnect.

Also, the procedure is for specifying 10 to VLAN ID of the network for the public LAN, 20 to VLAN ID of the network for the cluster interconnect, and 30 to VLAN ID of the network for a storage.

[Setting node1]

Set the system.

In the /etc/hosts file, define the IP address and the host name to be used.

172.16.0.10       node1-mng       # Administrative LAN IP address of node1
172.16.101.10     node1-gyomu     # Public LAN IP address of node1
172.16.102.10     node1-cf        # IP address for CF of node1
172.16.103.10     node1-storage   # IP address for storage connection of node1
172.16.0.11       node2-mng       # Administrative LAN IP address of node2
172.16.101.11     node2-gyomu     # Public LAN IP address of node2

172.16.103.11     node2-storage   # IP address for storage connection of node2
172.16.101.100    takeover        # Takeover IP address
172.16.101.1      gw-gyomu        # Public LAN gateway IP address
