Sun Cluster 3.0-3.1 With Sun StorEdge 9900 Series Storage Device Manual

ProcedureHow to Add a Storage Array to an Existing Cluster

Use this procedure to add a new storage array to a running cluster.

This procedure defines Node A as the node with which you begin working. Node B is another node in the cluster.

If you need to add a storage array to more than two nodes, repeat Step 22 through Step 37 for each additional node that connects to the storage array.

Steps

  1. Power on the storage array.

    Note –

    The storage array requires approximately 10 minutes to boot.

    Contact your service provider to power on the storage array.

  2. If you plan to use multipathing software, verify that the storage array is configured for multipathing.

    Contact your service provider to verify that the storage array is configured for multipathing.

  3. Configure the new storage array.

    Contact your service provider to create the desired logical volumes.

  4. Do you need to install a host adapter in Node A?

    Note –

    If you use multipathing software, each node requires two paths to the same set of LUNs.

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

  5. Is the host adapter that you are installing the first host adapter on Node A?

    • If no, proceed to Step 6.

    • If yes, contact your service provider to install the support packages and configure the drivers before you proceed to Step 6.

  6. Is your node enabled with the Solaris dynamic reconfiguration (DR) feature?

    • If yes, install the host adapter.

      For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter or updated information on the manufacturer's web site.

    • If no, shut down this node to install the host adapter(s). Proceed to Step 7.

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

    Record this information because you use this information in Step 37 of this procedure to return resource groups and device groups to these nodes.


    # scstat

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

  8. Shut down and power off Node A.

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

  9. Install the host adapter in Node A.

    For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter or updated information on the manufacturer's web site.

  10. Power on and boot Node A into noncluster mode.

    For the procedure about how to boot a node in noncluster mode, see your Sun Cluster system administration documentation.

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

  12. Attach the storage array to Node A.

    Contact your service provider to install a fiber-optic cable between the storage array and your node.

  13. Configure the host adapter and the storage array.

    Contact your service provider to configure the adapter and storage array.

  14. If you plan to install multipathing software, which multipathing solution do you plan to install?

  15. SPARC: Install Sun StorEdge 9900 Dynamic Link Manager (Sun SDLM) software and any required patches for Sun SDLM software support on Node A.

    For the procedure about how to install the Sun SDLM software, see the documentation that shipped with your storage array.

  16. Shut down Node A.

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

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


    # boot -r

  18. On Node A, configure all controllers that are affected by the new physical path.


    # cfgadm -c configure cN

  19. On Node A, verify that the same set of LUNs is visible to the expected controllers.


    # format

    See the format command man page for more information about how to use the command.

  20. On Node A, update the paths to the device ID instances.


    # scdidadm -C
# scdidadm -r

  21. (Optional) On Node A, verify that the device IDs are assigned to the new storage array.


    # scdidadm -l

  22. Do you need to install a host adapter in Node B?

    Note –

    If you use multipathing software, each node requires two paths to the same set of LUNs.

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

  23. Is the host adapter that you are installing the first host adapter on Node B?

    • If no, proceed to Step 24.

    • If yes, contact your service provider to install the support packages and configure the drivers before you proceed to Step 24.

  24. Is your node enabled with the Solaris dynamic reconfiguration (DR) feature?

    • If yes, install the host adapter.

      For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter or updated information on the manufacturer's web site.

    • If no, proceed to Step 25.

  25. Shut down and power off Node B.

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

  26. Install the host adapter in Node B.

    For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter or updated information on the manufacturer's web site.

  27. If necessary, upgrade the host adapter firmware on Node B.

Next Steps

The best way to enable multipathing for a cluster is to install and enable it before installing the Sun Cluster software and enabling the cluster. For this procedure, see How to Install Sun Multipathing Software in Sun Cluster Software Installation Guide for Solaris OS.
