Solaris 7 (SPARC Platform Edition) Installation Library

To Upgrade a System

  1. Consider the following information before you upgrade an existing system to a new version of the Solaris operating environment.

    • Check the section "Software Features No Longer Supported" in the Solaris Release Notes and your vendor release notes to see if there is any software that you use that is no longer provided in the new release.

    • See Chapter 2, What's New at a Glance and your vendor release notes to see if any of the changes or enhancements to the Solaris operating environment will affect anything that you currently do.

    • See the documentation that came with your system to make sure your system and devices are supported by the new release.

    • Check other software documentation.

      Caution - Caution -

      To avoid loss of data during upgrade, check Table 5-1 for known problems. This list is not complete. Always check co-packaged, vendor, and third-party software documentation for upgrading instructions.

      Problem Summary 

      SolsticeTM DiskSuiteTM

      Metadevices cannot be upgraded automatically. For instructions, see Appendix B, "Upgrading to Other Solaris Versions," in the Solstice DiskSuite Reference Guide.


      If you start the upgrade process by shutting down the system using init 0, you can lose data. See the Prestoserve documentation for shutdown instructions.

    • Check for all the available patches that you may need. The most updated patch list is provided by SunSolveTM on the internet (

  2. Back up your system.

    Always back up existing file systems before using the upgrade option and installing a new version of the Solaris operating environment. Backing up file systems means copying them to removable media (such as tape) to safeguard data against loss, damage, or corruption. If you do not have a backup procedure in place, see "To Back Up a System" to find out how to perform a full backup of file systems. For information on setting up scheduled backups and using other backup commands, see the System Administration Guide, Volume I.

  3. Insert the Solaris CD into the CD-ROM drive.

  4. Boot the system from the Solaris CD.

    Get your system to the ok prompt and type:

    boot cdrom

    Note -

    For older SPARCTM-based systems, use the following boot command: boot sd(0,6,2)

    Note -

    If you experience any problems from this point on, see Chapter 6, Troubleshooting.

  5. Wait for booting to complete.

    After you type the boot command, the system will go through a booting phase where various hardware and system components are checked. This lasts for several minutes. While the system is rebooting, you may should see messages similar to the following:

    ok boot cdrom
    Booting from: sd(0,6,2)
    SunOS Release x.x Version [UNIX(R) System V Release]
    Copyright (c), Sun Microsystems, Inc.
    Configuring devices 
    Starting OpenWindows...
  6. Follow the on-screen instructions to install the Solaris operating environment.

    The Solaris installation program is a menu-driven, interactive step-by-step guide to installing the Solaris operating environment. It also provides online help to answer your questions.

  7. Wait while the Solaris operating environment is installed on the system.

    A log of the installation (how the system was installed) is saved to the following files:

    • Before the system reboots: /a/var/sadm/system/logs/upgrade_log

    • After the system reboots: /var/sadm/system/logs/upgrade_log
