How to Replace a Host Adapter When Using a Single, Dual-Port HBA to Provide Both Paths to Shared Data

Before You Begin

This procedure relies on the following prerequisites and assumptions.

• You are using a single, dual-port HBA to provide the redundant paths to your shared data.

  For an explanation of the limitations and risks of using this configuration, see Configuring Cluster Nodes With a Single, Dual-Port HBA in Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS.

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

• Your nodes are not configured for dynamic reconfiguration.

  You cannot use dynamic reconfiguration for this procedure when using a single HBA.

• Node A is the node with the failed host adapter.

Steps

1. If you are using scalable and failover services, determine the resource groups and device groups that are running on Node A.

   Record this information because you use it in Step 18 of this procedure to return resource groups and device groups to Node A.

   # scstat

2. Record the details of metadevices that are affected by the failed host adapter.

3. SPARC: If you are using Oracle Real Application Clusters, shut down all RAC instances running in your cluster.

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

4. Shut down the cluster.

   For the full procedure about how to shut down a cluster, see your Sun Cluster system administration documentation.

5. Power off Node A.

6. Replace the failed host adapter.

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

7. Power on Node A.

8. Boot all nodes into cluster mode.

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

9. 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.

10. Perform any volume management maintenance procedures that are necessary to fix any metadevices affected by this procedure.

    For more information, see your volume manager software documentation.

11. (Optional) If necessary, return the resource groups and device groups you identified in Step 5 to Node A.

    # scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename

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

12. (Optional) Bring all Oracle Real Application Clusters instance online.

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