This document is about the ExpressCluster X configuration manual, which introduces how to use ExpressCluster X to set up a two-node cluster configuration (for duplication).
This guide explains how to configure a two-node cluster using ExpressCluster X for failover and shared resources. It covers setting up failover groups, shared disks, floating IP addresses, and installing the MasterScope SystemManager G manager on active and standby servers. It also includes steps for switching between nodes and uninstalling the system.
The guide assumes ExpressCluster X is already installed and provides detailed procedures for configuring shared resources, installing the manager, and managing licenses for both active and standby nodes.
ExpressCluster X is an NEC product that can be used to switch running processes between nodes in a duplicated system.
Set up shared resources by defining floating IP addresses and shared (mirror) disks through the WebManager interface.
