Solaris 8 Maintenance Update 5 Installation Guide

Chapter 2 Installing the Solaris 8 Maintenance Update 5

This chapter describes how to install your Solaris 8 MU5 software. If you want to install the Solaris 8 MU5 software as part of a custom JumpStartTM installation, refer to the Solaris 8 Advanced Installation Guide.

Time Considerations

The Solaris 8 MU5 installation procedure is faster than the installation of the individual MU5 patches. The Solaris 8 MU5 installation time varies depending on:

If you install the MU5 with the backout option disabled, installation will proceed more quickly. However, you will not be able to back out any of the patches MU5 delivers.


The MU5 may only be installed on a system running the Solaris 8, Solaris 8 6/00, Solaris 8 10/00, Solaris 8 1/01, or Solaris 8 4/01 operating environment.

Space requirements per file system vary depending on:

The install_mu script performs a space analysis and reports the space needed per file system, including back out space if applicable. The space calculations take several minutes to complete.

The install_mu script does not proceed if it determines that space is lacking in one or more file systems. Although the patch installation space needed is calculated fairly precisely, the backout data space need is estimated and the reported need may be higher than the actual need.

If you are certain that you have enough space to apply the patch set (and backout data if desired) and you want to bypass the space calculation, run install_mu with the -f option.

Installing the Solaris 8 MU5

Solaris 8 MU5 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, Solaris 8 1/01, or Solaris 8 4/01 operating environment.

Note -

Diskless client systems are not supported in MU5.

It is best to reboot your system in single-user mode before installing MU5 because MU5 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 MU5 image is on the network rather than on a CD, you must copy the MU5 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 MU5 image, you will need to install MU5 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.

When in single-user, or multi-user mode, you must reboot your system after MU5 is installed. Do not use the exit command. If exit is used, the system is brought to init 3 and no one can log in until the system is rebooted. If the root user has logged out and no other root users remain logged in, the system must be rebooted. See Chapter 4, Known Problems, for more detail.

Note -

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

To install the Solaris 8 MU5 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 MU5 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 MU5 image, go to Step 9.

  8. To mount the MU5 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 MU5 image, type:

      # cd local_directory
      # ./install_mu options
    • From the MU5 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




    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. 


    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.


    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.
  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 MU5.

  11. Type your login name and password:

    login: login
    password: password

Identifying the Version of Your Solaris 8 Maintenance Update

To identify the version of your Solaris 8 MU software, type:

# cat /etc/release

To identify the patches the MU software applied to your system, type:

 # showrev -p

Note -

If you compare the showrev -p output from applying the Solaris 8 MU5 software to the showrev -p output from installing the Solaris 8 7/01 operating environment, you will note that the following patches are not applied in the MU5 installation:

These patches are needed to generate the Solaris 8 7/01 operating environment, but are not needed to apply the Solaris 8 MU5 patches.
