In this scenario, we are replacing the hardware which hosts the wasna01 node.
|
This scenario covers planned maintenance. Thus, you should not use this in case of a hardware problem. If recover from a hardware failure by replacing the hardware, you can follow the description from Chapter 14, Backup and recovery of ND configuration. The approach described there requires a recent backup of your WebSphere configuration using backupConfig or a file system backup. |
The new hardware is configured to contain the exact same configuration as the removed node when it is defined in the cell. Obviously, to ensure HA, the node to be replaced must not be the only physical machine in the environment and the remaining systems should be able to handle the additional workload.
We recommend reading the entire section before performing the task.
