Prerequisites
For the complete recovery of a failed node the following prerequisites have to be fulfilled:
The installation files for IBM WAS Network Deployment V5.1 are available. All previously installed fixes and fixpacks are available. A previously saved configuration backup file as produced by the backupConfig command is available. The default filename of a backup archive is <WAS_HOME>/bin/WebSphereConfig_yyyy-mm-dd.zip. Additionally, some properties files are not restored, because they are located outside the <WAS_HOME>/config directory subtree. In a cluster configuration these files are identical to the ones on the other cluster members in the cell. Depending on whether you adapted these files, you either have to repeat that configuration step, or to copy them manually from another cluster member or the Deployment Manager to the restored node. These files are as follows (not necessarily a complete list):
Property files, for example, security related files in the <WAS_HOME>/properties/ directory:
sas.client.properties
sas.server.properties
wsadmin.properties
... Files in the <WAS_HOME>/etc/ directory, for example, SSL keyring files like plugin-key.kdb, etc. The plug-in configuration file, if it was manually modified on the Web server node(s).
