Sun Cluster 3.0-3.1 With Sun StorEdge T3 or T3+ Array Manual for Solaris OS

ProcedureHow to Install a Storage Array in a New Cluster, Using a Partner-Group Configuration

Use this procedure to install and configure the first storage array partner groups in a new cluster. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster software installation documentation and your server hardware manual.

Make certain that you are using the correct procedure. This procedure contains instructions about how to install a partner group into a new cluster, before the cluster is operational. The following procedures contain instructions for other array-installation situations:

Note –

When you upgrade firmware on a storage device or on an enclosure, redefine the stripe size of a LUN, or perform other LUN operations, a device ID might change unexpectedly. When you perform a check of the device ID configuration by running the scdidadm -c command, the following error message appears on your console if the device ID changed unexpectedly.


device id for nodename:/dev/rdsk/cXtYdZsN does not match physical 
device's id for ddecimalnumber, device may have been replaced.

To fix device IDs that report this error, run the scdidadm -R command for each affected device.

Steps

  1. Install the host adapters in the nodes to be connected to the storage arrays.

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

  2. Install the Fibre Channel (FC) switches.

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

    Note –

    If you are using two FC switches and Sun SAN software to create a storage area network (SAN), see SAN Considerations for more information.

  3. Are you installing Sun StorEdge T3+ arrays?

    • If no, proceed to Step 4

    • If yes, install the media interface adapters (MIAs) in the Sun StorEdge T3 arrays that you are installing, as shown in Figure 1–2.

      Figure 1–2 Installing a Partner-Group Configuration

      Illustration: The preceding context describes the graphic.

      For the procedure about how to install a media interface adapter (MIA), see the Sun StorEdge T3 and T3+ Array Configuration Guide.

  4. If necessary, install GBICs or SFPs in the FC switches, as shown in Figure 1–2.

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

  5. Set up a Reverse Address Resolution Protocol (RARP) server on the network on which the new storage arrays are to reside.

    This RARP server enables you to assign an IP address to the new storage arrays. Assign an IP address by using the storage array's unique MAC address. For the procedure about how to set up a RARP server, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  6. Cable the storage arrays, as shown in Figure 1–2.

    1. Connect the storage arrays to the FC switches by using fiber-optic cables.

    2. Connect the Ethernet cables from each storage array to the LAN.

    3. Connect interconnect cables between the two storage arrays of each partner group.

    4. Connect power cords to each storage array.

    For the procedure about how to install fiber-optic, Ethernet, and interconnect cables, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  7. Power on the storage arrays. Verify that all components are powered on and functional.

    For the procedure about how to power on the storage arrays and verify the hardware configuration, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  8. Administer the storage arrays' network settings.

    Use the telnet command to access the master controller unit and administer the storage arrays. For the procedure on how to administer the storage array network addresses and settings, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

    The master controller unit is the storage array that has the interconnect cables attached to the second port of each interconnect card, when viewed from the rear of the storage arrays. For example, Figure 1–2 shows the master controller unit of the partner group as the lower storage array. In this diagram, the interconnect cables are connected to the second port of each interconnect card on the master controller unit.

  9. Install any required storage array controller firmware.

    For partner-group configurations, use the telnet command to access the master controller unit. Install the required controller firmware.

    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. Ensure that each storage array has a unique target address.

    For the procedure about how to verify and assign a target address to a storage array, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

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

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  12. Ensure that the mp_support parameter for each storage array is set to mpxio.

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  13. Ensure that both storage array controllers are online.

    For more information about how to correct the situation if both controllers are not online, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  14. (Optional) Configure the storage arrays with the desired logical volumes.

    For the procedure about how to create and initialize a logical volume, see the Sun StorEdge T3 and T3+ Array Administrator's Guide. For the procedure about how to mount a logical volume, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  15. Reset the storage arrays.

    For the procedure about how to reboot or reset a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  16. On all nodes, install the Solaris operating environment. Apply the required Solaris patches for Sun Cluster software and storage array support.

    For the procedure about how to install the Solaris operating environment, see How to Install Solaris Software in Sun Cluster Software Installation Guide for Solaris OS

  17. Install any required patches or software for Sun StorEdge Traffic Manager software support to nodes.

    For the procedure about how to install the Sun StorEdge Traffic Manager software, see How to Install Sun Multipathing Software in Sun Cluster Software Installation Guide for Solaris OS.

  18. On all nodes, update the /devices and /dev entries.


    # devfsadm -C

  19. On all nodes, confirm that all storage arrays that you installed are visible. 


    # luxadm display
