How to Replace a Host Adapter When Using Failover and Scalable Data Services Only

Before You Begin

This procedure relies on the following prerequisites and assumptions.

• You are not using Oracle Real Application Clusters. If you are using Oracle Real Application Clusters, follow the instructions in SPARC: How to Replace a Host Adapter When Using Oracle Real Application Clusters 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 Oracle Real Application Clusters?

   • If yes, follow the instructions in SPARC: How to Replace a Host Adapter When Using Oracle Real Application Clusters 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 resource groups and device groups that are running on Node A.

   Record this information because you use this information in Step 17 of this procedure to return resource groups and device groups to Node A.

   # scstat

3. (Optional) If necessary, move all resource groups and device groups off Node A.

   # scswitch -S -h nodename

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

   # scstat -q

   • If no, skip this step.

   • 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 Solstice DiskSuite/Solaris Volume Manager submirrors or VERITAS Volume Manager plexes on the storage array.

   For more information, see your Solstice DiskSuite/Solaris Volume Manager or 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 16 of this procedure to reattach submirrors on the storage array. For more information about how to determine which submirrors or plexes are affected, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.

7. Is Node A enabled with the Solaris 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 DR feature?

    • If yes, perform any DR-specific steps and skip to Step 15.

    • If no, proceed to Step 12.

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

12. Power on Node A.

13. x86: Set the HBA ports to ensure that each array has a unique SCSI address.

    For instructions on setting SCSI initiator IDs in x86 based systems, see x86: How to Install a Storage Array in a New X86 Based Cluster.

14. Boot Node A into cluster mode.

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

15. 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.

16. Reattach the Solstice DiskSuite/Solaris Volume Manager submirrors or VERITAS Volume Manager plexes on the storage array.

    For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.

17. (Optional) If necessary, return the resource groups and device groups you identified in Step 2 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.

18. Did you relocate the quorum device in Step 4?

    • If no, this step completes the procedure.

    • If yes, and you want the cluster configured as it was before replacing the host adapter, relocate the quorum device function back to this storage array.

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