Installing the Solaris 8 MU4

Solaris 8 MU4 software can only be installed if the system running install_mu is already running the Solaris 8, Solaris 8 6/00, Solaris 8 10/00, or Solaris 8 1/01 operating environment.

Note - Diskless client systems are not supported in MU4.

It is best to reboot your system in single-user mode before installing MU4 because MU4 applies patches to system libraries. Individual systems in a multiuser system will be unstable if any processes have mapped to an unpatched version of a library and later attempt to map to different sections of the old library.

In single-user mode, network services are not available. If the MU4 image is on the network rather than on a CD, you must copy the MU4 image from the network to your local system before booting your system in single-user mode.

If it is not possible to reboot the system in single-user mode or if you do not have enough disk space to make a local copy of the MU4 image, you will need to install MU4 using NFS in multiuser mode. In this case, you should have the system in as quiet a state as possible, without users logged on or running jobs.

Note - Be sure that you have backed up your system's operating system before proceeding.

To install the Solaris 8 MU4 software:

  1. Make sure that no important user or system processes are running.

  2. Exit the current session.

    The CDE login screen appears.

  3. Click the Options button and select Command Line Login.

    The system prompts you to log in.

  4. Type your login name as root and type the root password:
    login: root
password: root password

  5. Reboot in single-user mode. From the root shell prompt, type:
    # reboot -- -s

    Note - Changing the run level from multiuser mode to single-user mode with the shutdown or init command might leave the vold process running. This process can cause problems mounting the MU4 CD in single-user mode.

  6. Type the root password.

    Check that the system displays the following message and is now in system maintenance mode.

  7. Determine where you are running the install_mu command.

    • If you are running install_mu from the CD, go to Step 8.

    • If you are running install_mu from a local copy of the MU4 image, go to Step 9.

  8. To mount the MU4 CD, place the CD in the drive and from the root shell prompt, type:
    # mount -o ro -F hsfs /dev/dsk/c0t6d0s0 /cdrom

    Note - In some cases the CD-ROM drive might be on a controller other than c0 or a target other than t6, which would require a different path to the CD-ROM device. Check with your system administrator if you have questions about mounting the CD-ROM drive.

  9. Run install_mu.

    • From a local copy of the MU4 image, type: 
      # cd local_directory
# ./install_mu options

    • From the MU4 CD, type: 
      # cd /cdrom
# ./install_mu options

    You can use the following options on the command line.

    Table 2-1. Command-Line Options for install_mu

    Option

    Description

    -d

    Specifies that patches will not be backed up. Using this argument decreases the time to install the software, but it also prevents you from backing out individual patches. Cannot be specified with -B option.

    -p patchdir

    Specifies directory that includes all the patches.

    -q

    Disables the display of dots that indicate install_mu activity.

    -B backoutdir

    Specifies that the backout data is saved in the indicated directory. Cannot be specified with the -d option.

    -f

    Forces installation of patch set without checking for sufficient disk space. Using this option saves time, but you must use it only if you are certain that you have enough space.

    When the installation is complete, the following message appears. 
    install_mu completed at date_time.

    • If you see this message, go to Step 10.

    • If you encounter any errors, go to Chapter 5.

  10. Reboot the system by typing:
    # sync ; reboot

    You are then prompted for a login.

    Note - To prevent the library conflict problem, you must reboot your system after installing MU4.

  11. Type your login name and password:
    login: login
password: password
