Sun Cluster 3.0 Installation Guide

How to Install the Solaris Operating Environment

If you are not using the scinstall(1M) custom JumpStart installation method to install software, perform this task on each node in the cluster.

  1. Ensure that the hardware setup is complete and connections are verified before installing Solaris software.

    Refer to Sun Cluster 3.0 Hardware Guide and your server and storage device documentation for details.

  2. On each node of the cluster, determine whether the local-mac-address variable is correctly set to false.


    # /usr/sbin/eeprom local-mac-address?

    • If the command returns local-mac-address=false, the variable setting is correct. Proceed to Step 3.

    • If the command returns local-mac-address=true, change the setting to false.


      # /usr/sbin/eeprom local-mac-address?=false

      The new setting becomes effective at the next system reboot.

  3. Have available your completed "Local File System Layout Worksheet" from Sun Cluster 3.0 Release Notes.

  4. Update naming services.

    Add address-to-name mappings for all public hostnames and logical addresses to any naming services (such as NIS, NIS+, or DNS) used by clients for access to cluster services. See "IP Addresses" for planning guidelines.

    You also add these addresses to the local /etc/inet/hosts file on each node during the procedure "How to Configure the Name Service Switch".

  5. If you are using a cluster administrative console, display a console screen for each node in the cluster.

    If the Cluster Control Panel is installed and configured on your administrative console, you can use the cconsole(1M) utility to display the individual console screens. Otherwise, you must connect to the consoles of each node individually.

    To save time, you can install the Solaris operating environment on each node at the same time. Use the cconsole utility to install all nodes at once.

  6. Are you installing a new node to an existing cluster?

    • If no, proceed to Step 7.

    • If yes, perform the following steps to create a mount point on the new node for each cluster file system in the cluster.

    1. From another, active node of the cluster, display the names of all cluster file systems.


      % mount | grep global | egrep -v node@ | awk `{print $1}'

    2. On the node you are adding to the cluster, create a mount point for each cluster file system in the cluster.


      % mkdir -p mountpoint

      For example, if a file system name returned by the mount command was /global/dg-schost-1, run mkdir -p /global/dg-schost-1 on the node being added to the cluster.

  7. Install the Solaris operating environment as instructed in the Solaris installation documentation.

    Note -

    You must install all nodes in a cluster with the same version of the Solaris operating environment.

    You can use any method normally used for installing the Solaris operating environment to install the software on new nodes being installed into a clustered environment. These methods include the Solaris interactive installation program, Solaris JumpStart, and Solaris Web Start.

    During installation, do the following.

    • Install at least the End User System Support software group. You might need to install other Solaris software packages which are not part of the End User System Support software group, for example, the Apache HTTP server packages. Third-party software, such as Oracle, might also require additional Solaris packages. Refer to third-party documentation for any Solaris software requirements.

      Note -

      Sun Enterprise E10000 servers require the Entire Distribution + OEM software group.

    • Create a file system of at least 100 MBytes with its mount point set as /globaldevices, as well as any file-system partitions needed to support your volume manager software. Refer to "System Disk Partitions" for partitioning guidelines to support Sun Cluster software.

      Note -

      The /globaldevices file system is required for Sun Cluster software installation to succeed.

    • Answer no when asked if you want automatic power-saving shutdown. You must disable automatic shutdown in Sun Cluster configurations. Refer to the pmconfig(1M) and power.conf(4) man pages for more information.

    • For ease of administration, set the same root password on each node.

    Note -

    The Solaris interface groups feature is disabled by default during Solaris software installation. Interface groups are not supported in a Sun Cluster configuration and should not be enabled. Refer to the ifconfig(1M) man page for more information about Solaris interface groups.

  8. Install any Solaris software patches.

    Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.

  9. Install any hardware-related patches and download any needed firmware contained in the hardware patches.

    Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.
