Sun Cluster 3.1 - 3.2 With Sun StorEdge T3 or T3+ Array Manual for Solaris OS

ProcedureHow to Install a Storage Array in a New Cluster Using a Single-Controller Configuration

Use this procedure to install and configure the first storage array in a new cluster, using a single-controller configuration. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster software installation documentation and your server hardware manual.

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 cldevice check or 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 cldevice repair or scdidadm -R command for each affected device.

  1. Install the host adapters in the nodes that are to be connected to the storage array.

    To install host adapters, see the documentation that shipped with your host adapters and nodes.

  2. Install the FC hubs/switches.

    To install FC hubs/switches, see the documentation that shipped with your FC hub/switch hardware.

    Note –

    If you are using two FC switches and Sun SAN software to create a storage area network (SAN), see SAN Solutions in a Sun Cluster Environment in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS for more information.

  3. 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 array by using each storage array's unique MAC address.

    To set up a RARP server, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  4. If you are not adding a StorEdge T3+ array, install the media interface adapters (MIAs) in the storage array that you are installing, as shown in Figure 1–1.

    To install a media interface adapter (MIA), see the Sun StorEdge T3 and T3+ Array Configuration Guide.

  5. If you are adding a StorEdge T3+ array, and if it is necessary, install gigabit interface converters (GBICs) or Small Form-Factor Pluggables (SFPs) in the FC hubs/switches, as shown in Figure 1–1.

    The GBICs or SFPs let you connect the FC hubs/switches to the storage array that you are installing. To install an FC hub/switch GBIC or an SFP, see the documentation that shipped with your FC hub/switch hardware.

  6. Install fiber-optic cables between the FC hubs/switches and the storage array, as shown in Figure 1–1.

    To install a fiber-optic cable, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

  7. Install fiber-optic cables between the FC hubs/switches and the nodes, as shown in Figure 1–1.

  8. Install the Ethernet cables between the storage array and the Local Area Network (LAN), as shown in Figure 1–1.

    Illustration: The preceding context describes the graphic.

    Note –

    Figure 1–1 shows how to cable two storage arrays to enable data sharing and host-based mirroring. This configuration prevents a single-point of failure.

  9. Install power cords to each storage array that you are installing.

  10. Power on the storage array and confirm that all components are powered on and functional.

    Note –

    The storage array might require a few minutes to boot.

    To power on a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  11. (Optional) Configure the storage array with logical volumes.

    To configure the storage array with logical volumes, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  12. Access each storage array that you are adding. Install the required controller firmware for the storage array.

    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.

  13. Ensure that this new storage array has a unique target address.

    To verify and assign a target address, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

  14. Reset the storage array.

    To reboot or reset a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  15. Install to the nodes the Solaris operating environment. Apply any required Solaris patches for Sun Cluster software and storage array support.

    To install the Solaris operating environment, see your Sun Cluster software installation documentation. For the location of required Solaris patches and installation instructions for Sun Cluster software support, see your Sun Cluster release notes documentation. For a list of required Solaris patches for storage array support, see the Sun StorEdge T3 and T3+ Array Release Notes.
