Sun Cluster 3.0-3.1 With Sun StorEdge 6120 Array Manual for Solaris OS

How to Add a Single-Controller Configuration to an Existing Cluster

Use this procedure to add a single-controller configuration to a running cluster. The following procedures contain instructions for other array-installation situations:

This procedure defines Node N as the node with which you begin working.

ProcedureHow to Perform Initial Configuration Tasks on the Storage Array

Steps
  1. Power on the storage array.


    Note –

    the storage array might require a few minutes to boot.


    For the procedure about how to power on a storage array, see the Sun StorEdge 6120 Array Installation Guide.

  2. Administer the storage array's network settings. Network settings include the following settings.

    • IP address

    • gateway (if necessary)

    • netmask (if necessary)

    • hostname

    For the procedure about how to set up an IP address, gateway, netmask, and hostname on a storage array, see the Sun StorEdge 6020 and 6120 Array System Manual.

  3. Ensure that the cache and mirror settings for each storage array are set to auto.

    For more information, see the Sun StorEdge 6020 and 6120 Array System Manual.

  4. Ensure that the mp_support parameter for each storage array is set to none.

    For more information about, see the Sun StorEdge 6020 and 6120 Array System Manual.

  5. Install any required controller firmware for the storage arrays you are adding.

    For the required controller firmware for the storage array, see the Sun StorEdge 6120 Array Release Notes.

    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.

  6. Reset the storage array to update the network settings and system settings that you changed.

    For the procedure about how to reboot or reset a storage array, see the Sun StorEdge 6020 and 6120 Array System Manual.

  7. Confirm that all storage arrays that you upgraded are visible to all nodes.


    # luxadm probe 
    

ProcedureHow to Connect the Storage Array to FC Switches

Steps
  1. Install the GBICs or SFPs in the storage array that you plan to add.

    For the procedure about how to install a GBICs or SFPs, see the Sun StorEdge 6120 Array Installation Guide.

  2. If necessary, install GBICs or SFPs in the FC switches.

    For the procedure about how to install a GBIC or an SFP, see the documentation that shipped with your FC switch hardware.

  3. Install the Ethernet cable between the storage array and the Local Area Network (LAN).

  4. If necessary, daisy-chain or interconnect the storage arrays.

    For the procedure about how to install interconnect cables, see the Sun StorEdge 6120 Array Installation Guide.

  5. Install a fiber-optic cable between the FC switch and the storage array.

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

ProcedureHow to Connect the Node to the FC Switches or the Storage Array

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 19 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 a host adapter in Node N?

  4. Is the host adapter that you are installing the first FC 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 Fibre Channel support packages installed?

    • If yes, proceed to Step 6.

    • If no, install the packages.

    The storage array packages are located in the Product directory of the Solaris CD-ROM. Add any necessary packages.

  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 the host adapter in Node N.

    For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter and node.

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

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

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

  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. If necessary, install the required Solaris patches for storage array support on Node N.

    For a list of required Solaris patches for storage array support, see the Sun StorEdge 6120 Array Release Notes.

  13. On the node, update the /devices and /dev entries.


    # devfsadm -C 
    
  14. Boot the node into cluster mode.

  15. On the node, update the paths to the DID instances.


    # scgdevs
    
  16. If necessary, label the new logical volume.

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

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


    # scdidadm -C
    # scdidadm -l
    
  18. Repeat Step 2 through Step 17 for each remaining node that you plan to connect to the storage array.

  19. (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.

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

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