As discussed earlier, two nodes will be configured in a network to complete tasks in this tutorial.
Please refer to the LifeKeeper for Linux Release Notes as well as the resource plan for the resource(s) to be protected (e.g., Oracle). Check to ensure that the correct operating system is selected and that the appropriate resources (e.g., disk space, memory, CPU, etc.) are available.
It is important to understand that two disks will be needed for each node. The first disk is used to boot the system (this has an operating system and the applications including LifeKeeper installed), while the other disk will be configured to replicate data from the “active” node to the “standby” node (note that the direction of data replication will change once a “switchover” occurs).
This guide assumes that the following resources are attached to each of the nodes:
Storage device for operating system & installing applications | |
|
Storage device for data replication between nodes | |
|
Memory | |
