Sun Cluster 3.0-3.1 With Sun StorEdge 6320 System Manual for Solaris OS

ProcedureHow to Connect the Node to the FC Switches

Steps

  1. Determine the resource groups and device groups that are running on all nodes.

    Record this information because you use this information in Step 20 of this procedure to return resource groups and device groups to these nodes.


    # scstat

  2. Move all resource groups and device groups off Node N.


    # scswitch -S -h from-node

  3. Do you need to install one or more host adapters in Node N?

  4. Is the host adapter that you that are installing the first host adapter on Node N?

    • If no, skip to Step 6.

    • If yes, determine whether the required drivers for the host adapter are already installed on this node. For the required packages, see the documentation that shipped with your host adapters.

  5. Are the required support packages already installed?

    • If yes, proceed to Step 6.

    • If no, install the packages.

    The support packages are located in the Product directory of the Solaris CD-ROM.

  6. Shut down and power off Node N.

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

  7. Install one or more host adapters in Node N.

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

  8. Power on and boot Node N into noncluster 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 N.

    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.

  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 or the Sun StorEdge 6320 System 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 6320 System Installation Guide.

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

  13. Perform a reconfiguration boot on Node N to create the new Solaris device files and links.


    # boot -r

  14. Are any devices that are associated with the volume you created at an unconfigured state?


    # cfgadm -al | grep disk

    • If no, proceed to Step 15.

    • If yes, configure the STMS paths.


      cfgadm -c configure controllerinstance

      For the procedure about how to configure STMS paths, see the Sun StorEdge Traffic Manager Installation and Configuration Guide.

      Note –

      You need to reboot if the cfgadm command does not configure the unconfigured devices that are associated with the volume you are creating. See the Sun StorEdge Traffic Manager Installation and Configuration Guide for more information.

  15. Update the Solaris device files and links.


    # devfsadm
    Note –

    You can wait for the devfsadm daemon to automatically update the Solaris device files and links, or you can run the devfsadm command to immediately update the Solaris device files and links.

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


    # scgdevs

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

    For the procedure about how to label a logical volume, see the Sun StorEdge 6320 System Reference and Service Manual.

  18. (Optional) On Node N, verify that the device IDs (DIDs) are assigned to the new storage array.


    # scdidadm -l

  19. Repeat Step 2 through Step 18 for each remaining node that you plan to connect to the storage array.

  20. (Optional) Return the resource groups and device groups that you identified in Step 1 to the original nodes.


    # 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.

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

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

Next Steps

The best way to enable multipathing for a cluster is to install the multipathing software and enable multipathing before installing the Sun Cluster software and establishing the cluster. For this procedure, see How to Install Sun Multipathing Software in Sun Cluster Software Installation Guide for Solaris OS. If you need to add multipathing software to an established cluster, see How to Install Sun Multipathing Software in Sun Cluster Software Installation Guide for Solaris OS and follow the troubleshooting steps to clean up the device IDs.
