How to Restore a Single Cluster Node
To restore a single node:
1. Replace the damaged node and ensure that it is connected to the network.
For information about replacing the hardware and verifying network
connections, refer to the Sun Cluster 3.x Hardware Guide and the server
documentation.
2. Reinstall the operating system and the Sun Cluster software on the
recovered node and reconfigure the node to join the cluster. For detailed
instructions, refer to the Sun Cluster Installation Guide.
3. Install the NetWorker software.
Important: The installation steps you perform vary depending on whether the
NetWorker server is set up as a highly available Sun Cluster resource or the
NetWorker server is set up outside of the cluster. For detailed installation and
configuration instructions for Sun Clusters, refer to the Legato NetWorker
Installation Guide, Solaris Version.
4. Restore the physical node’s private data using the nwrecover command.
Private data is data that is not available to all nodes in the cluster. For
information about recovering physical NetWorker clients, refer to the
Legato NetWorker Administrator’s Guide, UNIX Version.
