SPARC: How to Replace a Host Adapter When Using Oracle Real Application Clusters Only

Before You Begin

This procedure relies on the following prerequisites and assumptions.

• You are using Oracle Real Application Clusters only. If you are using other failover or scalable data services, follow the instructions in How to Replace a Host Adapter When Using Failover and Scalable Data Services Only or SPARC: How to Replace a Host Adapter When Using Both Failover and Scalable Data Services and Oracle Real Application Clusters.

• Except for the failed host adapter, your cluster is fully operational and all nodes are powered on.

If your nodes are configured for dynamic reconfiguration, see the Sun Cluster system administration documentation, and skip steps that instruct you to shut down the node.

Steps

1. Does your cluster use failover or scalable data services (other than Oracle Real Application Clusters)?

   • If yes, follow the instructions in How to Replace a Host Adapter When Using Failover and Scalable Data Services Only or SPARC: How to Replace a Host Adapter When Using Both Failover and Scalable Data Services and Oracle Real Application Clusters.

   • If no, proceed to Step 2.

2. Determine the Oracle instance that is running on Node A.

   # ps -ef | grep oracle

3. Shut down the Oracle Real Application Clusters instance and any other process on Node A that should be stopped before shutting down the node.

   For information about how to shut down and restart an Oracle instance in the RAC environment, refer to your Oracle documentation.

4. Determine if the storage device that are attached to the failed host adapter contains a quorum device.

   # scstat -q

   • If no, skip to Step 5.

   • If yes, add a new quorum device on a different storage device and remove the old quorum device.

     For procedures about how to add and remove quorum devices, see the Sun Cluster system administration documentation.

5. Detach the VERITAS Volume Manager plexes on the storage array attached to the failed host adapter.

   For more information, see your VERITAS Volume Manager documentation.

6. Record the details of disk groups and volumes affected by the failed host adapter

   Record this information because you use it in Step 15 of this procedure to reattach plexes on the storage array. For more information about how to determine which plexes are affected, see your VERITAS Volume Manager documentation.

7. Is Node A enabled with the Solaris dynamic reconfiguration (DR) feature?

   • If yes, perform any DR-specific steps and skip to Step 10.

   • If no, proceed to Step 8.

   For more information, see your Sun Cluster system administration documentation.

8. Shut down Node A.

   For the full procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.

9. Power off Node A.

10. Replace the failed host adapter.

    For the procedure about how to remove and add host adapters, see the documentation that shipped with your nodes.

11. Is Node A enabled with the Solaris dynamic reconfiguration feature?

    • If yes, perform any DR-specific steps and skip to Step 14.

    • If no, proceed to Step 12.

    For more information, see your Sun Cluster system administration documentation.

12. Power on Node A.

13. Boot Node A into cluster mode.

    For more information about how to boot nodes, see your Sun Cluster system administration documentation.

14. If necessary, upgrade the host adapter firmware on Node A.

    PatchPro is a patch-management tool that eases the selection and download of patches required for installation or maintenance of Sun Cluster software. PatchPro provides an Interactive Mode tool especially for Sun Cluster. The Interactive Tool makes the installation of patches easier. PatchPro's Expert Mode tool helps you to maintain your configuration with the latest set of patches. Expert Mode is especially useful for obtaining all of the latest patches, not just the high availability and security patches.

    To access the PatchPro tool for Sun Cluster software, go to http://www.sun.com/PatchPro/, click Sun Cluster, then choose either Interactive Mode or Expert Mode. Follow the instructions in the PatchPro tool to describe your cluster configuration and download the patches.

    For third-party firmware patches, see the SunSolve^SM Online site at http://sunsolve.ebay.sun.com.

15. Reattach the VERITAS Volume Manager plexes on the storage array to their respective volumes.

    For more information, see your VERITAS Volume Manager documentation.

16. (Optional) Bring your Oracle Real Application Clusters instance online. This is the instance you identified in Step 2.

    For information about how to shut down and restart an Oracle instance in the RAC environment, refer to the Oracle 9iRAC Administration Guide.

17. (Optional) Did you relocate a quorum device in Step 4?

    • If no, this step completes the procedure.

    • If yes, and you want your configuration to use the same quorum structure after the host adapter replacement, relocate the quorum device function back to this storage array.

      For procedures about how to add and remove quorum devices, see the Sun Cluster system administration documentation.
