Adding a New Cluster Node Requires Cluster Reboot (4971299)

Problem Summary: When a node is added to the cluster that runs Sun Cluster Support for Oracle Real Application Clusters and uses the VxVM cluster feature, the cluster feature running on other nodes does not recognize the new node.

Workaround: A fix for this problem is expected to be made available by VERITAS in VxVM 3.5 MP4 and VxVM 4.0 MP2. The fix for VxVM 4.1 is currently available.

To correct the problem if a code fix is not yet available, restart the Oracle database and reboot the cluster nodes. This step synchronizes the Oracle UDLM and updates the VxVM cluster feature to recognize the added node.

Do not install and configure Sun Cluster Support for Oracle Real Application Clusters on the new node until after you perform this step.

1. From a cluster node other than the node that you just added, shut down the Oracle Real Application Clusters database.

2. Reboot the same node on which you shut down the Oracle database.

   # scswitch -S -h thisnode # shutdown -g0 -y -i6

   Wait until the node is fully rebooted back into the cluster before you proceed to the next step.

3. Restart the Oracle database.

4. Repeat Step 1 through Step 3 on each remaining node that runs Sun Cluster Support for Oracle Real Application Clusters.

   • If a single node is capable of handling the Oracle database workload, you can perform these steps on multiple nodes simultaneously.

   • If more than one node is required to support the database workload, perform these steps on one node at a time.
