Installing the Solaris 9 MU2

Solaris 9 MU2 software can only be installed if the system that is running install_mu is already running the Solaris 9 operating environment.

Relocatable root and service areas are not supported in the Solaris 9 MU2.

Ideally, you reboot your system in single-user mode before installing MU2 because MU2 applies patches to system libraries. Avoid introducing instability to individual systems in a multiuser system. Ensure that no processes have mapped to an unpatched version of a library. Otherwise, those processes might later attempt to map to different sections of the old library.

In single-user mode, network services are not available. You must copy the MU2 image from the network to your local system before booting your system in single-user mode.

You need to install MU2 by using NFS in multiuser mode if you meet one of the following criteria:

• You cannot reboot the system in single–user mode

• You do not have enough disk space to make a local copy of the MU2 image

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 mode or multiuser mode, you must reboot your system after MU2 is installed. Do not use the exit command. If the exit command 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.

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

To install the Solaris 9 MU2 software:

1. Ensure that no important user or system processes are running.

   Note –

   You must kill the powerd process if it is running.

   ---

2. Exit the current session.

   The CDE login screen is displayed.

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

6. Type the root password.

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

   Entering System Maintenance Mode Sun Microsystems Inc. SunOS 5.9 Generic May 2002 #

7. Run install_mu. From a local copy of the MU2 image, type:

   # cd local_directory # ./install_mu options

   You can use the following options at the command line.

   Table 2–1 Command-Line Options for install_mu

   Option	Description
   -d	Specifies that patches will not be backed up. Use of 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. Use of this option is quicker. However, use it only if you know that you have enough space.

8. When the installation is complete, check that the following message is displayed.

   install_mu completed at date_time.

   • If you see this message, go to Step 9.

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

9. 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 MU2.
