DOCUMENTATION: How is the cluster_add_node script used?

Solution



The cluster_add_node script is available from NetBackup 6.5.2 Release Update and NetBackup Operations Manager (NOM) 6.5.2 Release Update.  This script can be used to add a new node to an existing NetBackup/NOM cluster.  It can also be used if an existing node is rebuilt and rejoined to a NetBackup/NOM cluster.

Note: This script must be run from a node that is already in the cluster.

The following tasks must be completed before running cluster_add_node from a node that is already in NetBackup/NOM cluster:
1. The operating system and patch level on new node should be brought to the same level as existing node(s) in the cluster.

2. The cluster software and its patch level on new node should be brought to the same level as existing node(s) in the cluster.

3. The new node must be configured to become the member of the existing cluster following the instructions from cluster software documentation.  This includes, but is not limited to configuring the low level cluster interconnection links - for example, in the case of VERITAS Cluster Server, Low Latency Transport and Global Atomic Broadcast - on the new node. The new node should be configured such that it is able to communicate with existing nodes.

4. The new node must be configured so that the shared disk for the cluster can be mounted for failover.

5. The NetBackup/NOM software must be installed on the new node, following the directions in the NetBackup High Availability Guide or NetBackup 6.5.2  Documentation Updates (linked below).

6. Any NetBackup/NOM Release Updates should be applied to the new node so that its release version matches that of the existing nodes.

7. The remote shell (rsh/remsh) should be enabled for the root user on all nodes of the existing cluster as well as on the new node. (This can be disabled once the node addition is complete.)

Once all of the above tasks are completed, run the cluster_add_node script from an existing node as the root user:
# cd /usr/openv/netbackup/bin/cluster/util
# ./cluster_add_node -s <nbu/nom> -n <new_node_name>
