Sun Cluster 3.0-3.1 With Sun StorEdge 6130 Array Manual

ProcedureHow to Replace a Host Adapter

Use this procedure to replace a failed host adapter in a running cluster. This procedure defines Node A as the node with the failed host adapter that you are replacing.

Before You Begin

This procedure relies on the following prerequisites and assumptions.

  1. Determine the resource groups and device groups that are running on Node A.

    Record this information because you use this information in Step 9 of this procedure to return resource groups and device groups to Node A.


    # scstat
    
  2. Move all resource groups and device groups off Node A.


    # scswitch -S -h nodename
    
  3. 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.

  4. Power off Node A.

  5. Replace the failed host adapter.

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

  6. Do you need to upgrade the node's host adapter firmware?

    • If yes, boot Node A into noncluster mode. Proceed to Step 7.

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

    • If no, proceed to Step 8.

  7. 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 SunSolveSM Online site at http://sunsolve.ebay.sun.com.

  8. Boot Node A into cluster mode.

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

  9. Return the resource groups and device groups you identified in Step 1 to Node A.


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