Solaris 8 Maintenance Update 1 Installation Guide

Installing the Solaris 8 MU1

Solaris 8 MU1 software can only be installed if both the system running install_mu and the target systems are already running the Solaris 8 operating environment.

It is best to reboot your system in single-user mode before installing MU1 because MU1 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 MU1 image is on the network rather than on a CD, you must copy the MU1 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 MU1 image, you will need to install MU1 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 MU1 software:

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

Exit the current session.

The CDE login screen appears.

Click the Options button and select Command Line Login.

The system prompts you to log in.

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

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 MU1 CD in single-user mode.

Type the root password.

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

- If you are running install_mu from the CD, go to Step 7.
- If you are running install_mu from a local copy of the MU1 image, go to Step 8.

To mount the MU1 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.

Run install_mu.

From a local copy of the MU1 image, type:

# cd local_directory
# ./install_mu options

From the MU1 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 successfully.

If you see this message, go to Step 9.
If you encounter any errors, go to Chapter 5, Error Messages.

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 MU1.

Type your login name and password:
