The first resource to be created on LifeKeeper should be an IP resource. As discussed earlier, a client can find the Active Node using a Virtual IP Address. Below is the list of IP addresses that are referenced in this section.

IP Addresses for Nodes

Field
Value
node-a 10.20.1.10
node-b 10.20.2.10

IP Address for the IP Resource Based on the Scenario

In a cloud environment, please review Switching between Nodes in a Cloud Environment to identify the most applicable scenario before selecting an IP address.

Platform
Scenario
How to Select an IP Address Sample IP Addresses Used in this Guide Default Name of the IP Address
AWS Route Table Scenario IP address that is outside of the VPC CIDR 10.10.10.10 ip-10.10.10.10
Route 53 Scenario IP address that is assigned to the “active” node 10.20.1.10 realip
Elastic IP Scenario Not required to create an IP Resource. Skip this page.
Google Cloud
Azure An available IP address on the subnet 10.20.0.10 ip-10.20.0.10
On-premise environment

Configure an IP Resource

This example uses 10.10.10.10 as the IP address to be used for “Route Table Scenario“ in AWS.

1. Click the button in the LifeKeeper User Interface (or select Edit > Server > Create Resource Hierarchy).

  1. The Create Resource Wizard (on node-a) will be displayed and the type of resource to be protected can be selected. Select “IP” and then click “Next>”.

  1. Select the default values. The only field you need to enter is the virtual IP address 10.10.10.10 in the IP Resource field.
Field
Value
Switchback Type Intelligent
Server node-a
IP Resource 10.10.10.10
Net Mask 255.255.255.0

Note: This value may vary based on the network.

Network Interface eth0
IP Resource Tag ip-10.10.10.10

Values such as Net Mask are displayed based on how the local system is configured. Therefore the default values seen may vary.

  1. Once you confirm the resource is successfully created, click “Next>”.
  1. The next step is the “Pre-Extend Wizard (on node-a)”.

Select all of the defaults as shown below.

Field
Value
Target Server node-b
Switchback Type Intelligent
Template Priority 1
Target Priority 10

The Pre-Extend check should be successfully completed. Click “Next”.

  1. The next step is “Extend comm/IP Resource Hierarchy (on node-a)”. Click “Next” and fill in the fields.

Field
Value
Net Mask 255.255.255.0

Note: This value may vary based on the network.

Network Interface eth0
IP Resource Tag ip-10.10.10.10
  1. Now the resource is extended. Select “Finish”.

  1. The verification is now complete and the wizard can be closed.
  1. The IP Resource (ip-10.10.10.10) will be displayed on the LifeKeeper User Interface.

As we have seen, resources may be easily protected by answering the questions in the resource creation wizard. Most of the values are prepopulated based on an understanding of the environment and therefore minimal user interaction is required.
