PRIMECLUSTER Wizard for NAS 4.5 Configuration and Administration Guide

A.2.2 GLS (Multilink Ethernet) configuration

Set up Multilink Ethernet method using GLS referring to "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function".

1. Register an IP and host name in /etc/hosts. In scalable operation, register an IP and host name in /etc/hosts of all the nodes.

2. Set up mpnet0 for standby operation and mpnet0, mpnet1, … for scalable operation when editing /etc/opt/FJSVmpnet/conf/config. For scalable operation, all the mpnet interface setup should be the same.

   
   

   Example

   mpnet0 ether hme0:hme1
   mpnet1 ether hme0:hme1

   
   

3. Specify 1 for func-mode when editing /etc/opt/FJSVmpnet/conf/parameters. For trunk-mode, use the same load balancing as NAS.

   
   

   Example

   mpnet0 -:1:2
   mpnet1 -:1:2

   
   

4. Specify the host name that is registered at 1. in /etc/opt/FJSVmpnet/conf/hosts. This is used for the mpnet interface. For scalable operation, register all the mpnet interfaces.

   
   

   Example

   mpnet0 node1mpnet
   mpnet1 node2mpnet

   
   

5. Execute the “/opt/FJSVmpnet/cluster/bin/mpnet_copyfile -a” command and distribute the configuration file to all the nodes.

6. Execute the “/opt/FJSVmpnet/cluster/bin/mpnet_addrid -d mpnet interface name” command on each node and register resources. For standby operation, specify mpnet0 for the mpnet interface name. For scalable operation, specify a mpnet interface that is used for each node.
