Adding another node to the cluster

Follow these steps to add the second node to your Granta MI cluster.

  1. Install Granta MI on the new node following the same workflow documented in Installing and configuring Granta MI.
    Note: Do not install MI Data Flow. This should only be installed on one node in the cluster.
  2. In the Settings application, add the new node to the list of allowed One MI hostnames for the cluster:
    1. Open the One MI web application, then open Settings.
    2. Click to open the One MI settings page.
    3. Edit the One MI application server alternative machine names field (Allowed.OneMi.HostNames). For example, to add a node called mynode2 to the comma-separated list, you would include the hostname and FQDN as follows: 
      mynode2,mynode2.example.com
  3. To join the new node to the cluster, follow the steps in Enabling Cluster Mode, entering the cluster key you generated on the first node into the Cluster Key field on the Cluster tab of the MI Server Connection tool.
  4. Add the new node to your load balancer.
