Configuring Volume Management

The volume management feature enables you to do the following:

  • Increase data availability because you can mirror disks locally

  • Increase the number of available replicated partitions because you can create multiple soft partitions

The volume management software that is installed depends on the version of the Solaris operating system that you plan to install. For information on supported software versions, see the Netra High Availability Suite Foundation Services 2.1 6/03 Release Notes.

For a Netra 20 server with a Fibre Channel-Arbitrated Loop (FC-AL) disk as a master-eligible node, you must install the Volume Management feature of the Solaris operating system. For more information, see the Netra High Availability Suite Foundation Services 2.1 6/03 Hardware Guide.

To install the Volume Management software on the nodes of your cluster, perform one of the following procedures:

ProcedureTo Configure Basic Volume Management for Netra 20 Servers With FC-AL Disks

You can use the nhinstall tool to install and configure volume management for Netra 20 servers with FC-AL disks. Configure the nhinstall tool to support logical disk partitions for FC-AL disks by installing the volume management feature as follows:

  1. In the env_installation.conf file, set SOLARIS_INSTALL to ALL.

  2. Configure the cluster_definition.conf file:

    1. Set LOGICAL_SLICE_SUPPORT to YES.

    2. Set the SLICE definition for the last partition to replica.

    For a detailed example, see the cluster_definition.conf(4) man page.

  3. Run the nhinstall tool to install the Solaris operating system and Foundation Services on the master-eligible nodes.

    For more information, see To Launch the nhinstall Tool.

    The nhinstall tool installs and configures the appropriate volume management software depending on the version of the Solaris operating system you chose to install.

ProcedureTo Configure Advanced Volume Management

To configure advanced volume management, install the Solaris operating system and configure the Volume Management feature to suit your needs and then configure nhinstall to install only the Foundation Services.

  1. Install the Solaris operating system with volume management on the master-eligible nodes.

    For more information, see the documentation for your volume management software:

    • For Solaris 8, Solstice DiskSuite 4.2.1 Installation and Product Notes

    • For Solaris 9, Solaris Volume Manager Administration Guide

    This documentation is available at http://docs.sun.com.


    Note - Install the same packages of the same version of the Solaris operating system on both master-eligible nodes.

    Create identical disk partitions on the disks of both master-eligible nodes.


  2. Configure a physical Ethernet card interface that corresponds to the first network interface, NIC0.

  3. Configure the /etc/netmasks file.

    See the netmasks(4) man page.

  4. Configure the sizes of the disk partitions.

    For more information, see Table 3-2.

  5. If you plan to include diskless nodes in the cluster, install the Solaris services for diskless nodes:

    # /usr/sadm/bin/smosservice add -p sunrules -- \
    -x mediapath=mount_path \
    -x platform=sparc.sun4u.Solaris_9 \
    -x cluster=SUNWCuser \
    -x locale=en_US

    where mount-path is the directory where the Solaris distribution is mounted.

    • If you have installed Solaris 8, also install the JDK™ (Java Development Kit) software for the diskless nodes:
      # /usr/sbin/pkgadd -R /export/Solaris_8/usr_sparc.all \
      -M -d mount-path/Solaris_8/Product SUNWjdrt

    • If you have installed Solaris 9, the JDK for the diskless nodes is installed by the nhinstall tool automatically.

  6. In the env_installation.conf file, set SOLARIS_INSTALL to NONE.

    When SOLARIS_INSTALL is set to NONE, the Solaris services for the diskless environment are not installed, but the diskless nodes are configured.

  7. In the cluster_definition.conf file, do the following:

    1. Set the LOGICAL_SLICE_SUPPORT parameter to NO.

    2. For the SLICE parameter, specify the metadevice names of the disk partitions.

      For example:

      SLICE=d1 2048 /               -        logging

      For details on the SLICE parameter, see the cluster_definition.conf(4) man page.

  8. Run the nhinstall tool to install the Foundation Services on the master-eligible nodes.

    For more information, see To Launch the nhinstall Tool.
