5. ### 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: To Configure Basic Volume Management for Netra 20 Servers With FC-AL Disks To Configure Advanced Volume Management #### To 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: In the `env_installation.conf` file, set `SOLARIS_INSTALL` to `ALL`. Configure the `cluster_definition.conf` file: Set `LOGICAL_SLICE_SUPPORT` to `YES`. Set the `SLICE` definition for the last partition to `replica`. For a detailed example, see the `cluster_definition.conf`(4) man page. 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. #### To 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. 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. Configure a physical Ethernet card interface that corresponds to the first network interface, NIC0. Configure the `/etc/netmasks` file. See the `netmasks`(4) man page. Configure the sizes of the disk partitions. For more information, see Table 3-2. 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
7. 2. If you have installed Solaris 9, the JDK for the diskless nodes is installed by the `nhinstall` tool automatically. 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. In the `cluster_definition.conf` file, do the following: Set the `LOGICAL_SLICE_SUPPORT` parameter to `NO`. 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. Run the `nhinstall` tool to install the Foundation Services on the master-eligible nodes. For more information, see To Launch the `nhinstall` Tool.
