    For the procedure about how to boot a node in noncluster mode, see Chapter 3, Shutting Down and Booting a Cluster, in Sun Cluster System Administration Guide for Solaris OS.

  9. If necessary, upgrade the host adapter firmware on Node N.

    If you use the Solaris 8, Solaris 9, or Solaris 10 Operating System, Sun Connection Update Manager keeps you informed of the latest versions of patches and features. Using notifications and intelligent needs-based updating, Sun Connection helps improve operational efficiency and ensures that you have the latest software patches for your Sun software.

    You can download the Sun Connection Update Manager product for free by going to http://www.sun.com/download/products.xml?id=4457d96d.

    Additional information for using the Sun patch management tools is provided in Solaris Administration Guide: Basic Administration at http://docs.sun.com. Refer to the version of this manual for the Solaris OS release that you have installed.

    If you must apply a patch when a node is in noncluster mode, you can apply it in a rolling fashion, one node at a time, unless instructions for a patch require that you shut down the entire cluster. Follow the procedures in How to Apply a Rebooting Patch (Node) in Sun Cluster System Administration Guide for Solaris OS to prepare the node and to boot it in noncluster mode. For ease of installation, consider applying all patches at the same time. That is, apply all patches to the node that you place in noncluster mode.

    For a list of patches that affect Sun Cluster, see the Sun Cluster Wiki Patch Klatch.

    For required firmware, see the Sun System Handbook.

  10. If necessary, install a GBIC or an SFP in the FC switch or the storage array.

    For the procedure about how to install a GBIC or an SFP, see the documentation that shipped with your FC switch hardware. For the procedure on how to install a GBIC or an SFP, see the Sun StorEdge 6120 Array Installation Guide.

  11. Connect a fiber-optic cable between the FC switch and Node N.

    For the procedure about how to install a fiber-optic cable, see the Sun StorEdge 6120 Array Installation Guide.

  12. Install the required Solaris patches for storage array support on Node N.

    If you use the Solaris 8, Solaris 9, or Solaris 10 Operating System, Sun Connection Update Manager keeps you informed of the latest versions of patches and features.

  13. Perform a reconfiguration boot on Node N by adding -r to your boot instruction, to create the new Solaris device files and links.

    For the procedure about how to boot a node, see Chapter 3, Shutting Down and Booting a Cluster, in Sun Cluster System Administration Guide for Solaris OS.

  14. On Node N, update the paths to the DID instances.

    • If you are using Sun Cluster 3.2, use the following command: 


      # cldevice populate

    • If you are using Sun Cluster 3.1, use the following command: 


      # scgdevs

  15. If necessary, label the new storage array logical volume.

    For the procedure about how to label a logical volume, see the Sun StorEdge 6020 and 6120 Array System Manual.

  16. (Optional) On Node N, verify that the device IDs (DIDs) are assigned to the new LUNs.

    • If you are using Sun Cluster 3.2, use the following commands: 


      # cldevice clear
# cldevice list -v

    • If you are using Sun Cluster 3.1, use the following commands: 


      # scdidadm -C
# scdidadm -l

  17. Repeat Step 2 through Step 16 for each remaining node that you plan to connect to the storage array.

  18. (Optional) Restore the device groups to the original node.

    Perform the following step for each device group you want to return to the original node.

    • If you are using Sun Cluster 3.2, use the following command: 


      # cldevicegroup switch -n nodename  devicegroup1[ devicegroup2 ...]
      -n nodename

      The node to which you are restoring device groups.

      devicegroup1[ devicegroup2 …]

      The device group or groups that you are restoring to the node.

    • If you are using Sun Cluster 3.1, use the following command:


      # scswitch -z -D devicegroup -h nodename

  19. (Optional) Restore the resource groups to the original node.

    Perform the following step for each resource group you want to return to the original node.

    • If you are using Sun Cluster 3.2, use the following command: 


      # clresourcegroup switch -n nodename  resourcegroup1[ resourcegroup2 …]
      nodename

      For failover resource groups, the node to which the groups are returned. For scalable resource groups, the node list to which the groups are returned.

      resourcegroup1[ resourcegroup2 …]

      The resource group or groups that you are returning to the node or nodes.

    • If you are using Sun Cluster 3.1, use the following command: 


      # scswitch -z -g resourcegroup -h nodename

  20. Perform volume management administration to incorporate the new logical volumes into the cluster.

    For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.
