Configure IP cluster
Continue from the Control Room installer to the Cluster Configuration wizard page to configure resiliency requirements for the Control Room. Provide only one IP address to configure the Control Room on a single node. Provide multiple (three or more) IP addresses to configure the Control Room for high availability cluster.
Prerequisites
To install the Control Room in cluster mode:
- Ensure you have configured the default/custom and configurable firewall, port, and protocol requirements for Automation 360 deployment.
- Ensure the network location (UNC) path is configured to access the repository
files from all Control Room nodes in the
cluster.
You can configure Network Attached Storage (NAS) file sharing using Server Message Block (SMB) protocol.
- Ensure that all nodes that will be configured for the IP cluster are available for configuration before the installation. Also, provide the same list of IP addresses in the same order in all the nodes that are of the cluster when you install Control Room in these nodes.
- Ensure the existing cluster is in yellow or green state and all ports on the new node are open before adding a new node.
- Ensure to sign all the PowerShell files if the machine on which you are
installing Automation 360 has MachinePolicy as AllSigned or
UnRestricted. To view the MachinePolicy on your machine, run the following
command in PowerShell:
Get-ExecutionPolicy -List
You can find the following PowerShell files in the temp folder:- servicecredsvalidate
- getsysip
- getfileprodversion
- ecertprocess
- createstoragetables
- createpddtables
- createiqbottables
- createcrdbtables
- createaaridbtables
Remember: Before you upgrade from a previous version, shut
down the nodes gradually, and not at the same time, to ensure that the cluster does
not fail.
