Installing the Update

Note: Back up your ESX Server installation before installing this patch. Also, a minimum of 350MB of temporary free space on the / file system is required for installing this patch.

This update requires you to boot your server into Linux mode to perform the upgrade. When you are prompted to reboot at the end of the upgrade, the installer restarts your system to run ESX Server.

  1. Power off all virtual machines.
  2. Restart your system.
  3. At the LILO Boot Menu, select the option appropriate for your system.
    • For a boot-from-SAN installation, select esx-san-safe.
    • For all other installations, select linux-up.
  4. Log in as root to the ESX Server service console.
  5. Download the tar file into a temporary directory under /root on your ESX Server service console.
  6. Change your working directory to that directory.
  7. Verify the integrity of the package:
    # md5sum esx-2.5.5-184659-upgrade.tar.gz

    The md5 checksum output should match the following:
    8bf0a6a1e8b43ccb401f3a604c3be363 esx-2.5.5-184659-upgrade.tar.gz

  8. Extract the compressed tar archive:
    # tar -xvzf esx-2.5.5-184659-upgrade.tar.gz
  9. Change to the newly created directory:
    # cd esx-2.5.5-184659-upgrade
  10. Run the installer:
    # ./upgrade.pl
  11. The system updates have now been installed. A reboot prompt is displayed:
    Reboot the server now [y/n]?

    This update will not be complete until you reboot the ESX Server host. If you enter n to indicate that you will not reboot the server at this time, ESX Server displays the warning message: Please reboot the server manually. Your virtual machines will not run properly until this is done. If you see this message, you must manually reboot the server to complete the upgrade.

  12. At the reboot prompt, enter y to reboot the server.
