2 Installing the Prestoserve SunOS 4.x Software



Follow the instructions in this chapter to install the Prestoserve driver for systems running the Solaris 1.x (SunOS 4.x) operating system.

2.1 Space Requirements

Before you begin the installation, ensure that you have enough space available on your target system. The approximate amount of space required to install Sun Prestoserve is shown in Table 2-1. For exact space requirements for your operating system, look at the README file in the presto directory. Overhead refers to space that is used for saving the contents of files that are modified.

2.2 Mounting the CD-ROM

The software required to operate the Prestoserve product is shipped to you on a compact disk. Before you can install the software you must first mount the SunCD.

Place the Prestoserve CD-ROM in the CD drive and mount the local or remote CD-ROM using the commands appropriate to your operating system and hardware. See the Preface, "When You Need Help with UNIX Commands," for references to documentation that contain the correct procedures.

2.2.1 Selecting an Installation Tool

The Sun Prestoserve installation script is accessed using the CDmanager, which is available in /cdrom as two programs: cdm and cdmanager. cdm is the command line interface to CDmanager. cdmanager is the graphical user interface version of CDmanager which can be run only under OpenWindows. You can use either program to install the Prestoserve software.

    Table 2-2 CD-ROM Tools 

------------------------------------------------

                             
If you are installing from:  Use this program:
------------------------------------------------


                             
OpenWindows(TM)              cdmanager or cdm
                             
SunView(TM) (SunOS 4.x only) cdm
                             
Terminal                     cdm

------------------------------------------------

If you are running OpenWindows, you may find it more convenient to use the interactive cdmanager program, as shown next. If you are not running OpenWindows, you must use the menu-driven cdm program, as shown in "Installing with cdm" on page 2-4.

Note - This procedure works only with the SunOS 4.x operating system. If you are running Solaris 2.x follow the procedures in Chapter 3 or see your operating system documentation for the software installation tools available on your system.

The actual installation is performed by the Sun Prestoserve installation script. The sections that follow describe accessing the installation script using both cdmanager and cdm, refer to the appropriate section.

2.2.1.1 Installing with cdmanager

cdmanager is the graphical user interface version of CDmanager and runs only under OpenWindows. Follow these steps to run cdmanager:

    1. Enter the following command to move to the CD-ROM directory to access the CD-ROM:

    2. Type cdmanager & to open the CDmanager window:

    3. In the cdmanager window, click the left mouse button on the Prestoserve icon to select Prestoserve as the current application.
    4. Point the mouse arrow at the Options button near the top of the cdmanager window and hold down the right mouse button to display the Options pull-down menu.
    5. While holding down the right mouse button, slide the mouse pointer down the Options menu to select the install option and slide the mouse pointer to the right to select 2.3_Prestoserve.
    6. cdmanager displays an application installation window similar to the one shown below:

    The operating system release should be SunOS 4.1.1 or later.

    7. The screen stops scrolling and you are asked if you want to continue. Type y to continue.

The cdmanager utility now runs the installation script found on the CD-ROM. The installation script is described in detail in "Using the Installation Script" on page 2-6.

2.2.1.2 Installing with cdm

Follow these steps to run the command line interface version of CDmanager:

    1. Move to the /cdrom directory:

    2. Invoke cdm:

    Once cdm initializes, the application menu is displayed.

    3. Type 1, as shown above, to display the Application Selection screen:

    4. Select the application by typing the number that your display lists for Prestoserve. In this example the number for Prestoserve is 1, but this number varies for each system.
    5. Type y to begin the installation:

The cdm utility now runs the installation script found on the CD-ROM. The installation script is described in detail in the following section.

2.2.1.3 Remote Installation

To install the Prestoserve software using a CD-ROM device attached to a remote machine, refer to the User's Guide that came with your system for instructions about remote CD installations.

2.3 Using the Installation Script

The installation script copies files from the CD-ROM into other parts of the file system, installs the Prestoserve driver in the system directory, and builds a kernel that contains the driver. The kernel is installed in the root directory and is named: /vmunix.sysname.presto, where sysname is the configuration name of your system.

As the script runs, it queries you for information. In most cases, use the defaults supplied with the script. Press the RETURN key to select the defaults.

You can interrupt or stop this script at anytime. Once the Prestoserve software files are loaded on your system they require about 400 Kilobytes of disk space.

2.3.1 A Typical Installation

This section provides a step-by-step description of the functions performed by the installation script. The margin notes call your attention to lines requiring a response.

2.4 Booting the System with the New Kernel

The Prestoserve installation script has created a new kernel with the name displayed at the end of the installation procedure. You must now make the Prestoserve kernel the standard auto-boot kernel. To do this, you must boot first in the single-user mode and save the old kernel, then reboot your system.

2.4.1 Booting the System

To start your server in single-user mode, follow these steps:

    1. Turn your server off and then back on using the instructions that came with your system.
    2. Wait until the self-test is completed and a prompt is displayed.

    Depending on how your system is set up, you should see either a monitor prompt () or the OpenBoot prompt (ok).

    3. After the system self-test, stop the system from auto-booting any farther.

    If your system console is a Sun monitor, stop the system by typing L1-A.
    If you are using a terminal console, stop the system by pressing the BREAK key.

    4. Type the boot command with the kernel name that was displayed at the end of the installation script.

    If your system displays the () prompt, use the b (boot) command. For example:

    If your system displays the (ok) prompt, use the boot command. For example:

Note - The name of the kernel varies depending on your operating system. Ensure that you boot the kernel generated by the Prestoserve installation script.

    5. Look for this message:

Note - N depends on which SBus slot is used for the Prestoserve card. H depends on the SBus card configuration.

In addition, the driver prints initialization data. The data displayed is dependent on the state and the memory size of the Prestoserve hardware.

Note - If you do not see the boot time driver message, halt and power down the server and verify that the Prestoserve hardware is fully seated. In addition, make sure that you are booting the kernel that was configured for the device driver.

2.4.2 Saving and Linking the Kernel

Once the server is running in single-user mode you can link the kernel as follows.

    1. Save the old kernel, which could be the /vmunix file to a different name:

    2. Link the Prestoserve kernel to your current kernel as shown here:

    3. Boot the system according to the instructions that come with your specific operating system.

    The system comes up in multi-user mode.

Caution -

If you change /vmunix but don't reboot, some UNIX commands (such as ps and pstat) will stop functioning. However, as soon as you reboot, these commands will function normally.

2.4.3 Booting a Floppy Drive System

If you have a floppy drive on your system you may see this message at boot time:

You may ignore this message. When the software starts, it attempts to accelerate each file system defined in the /etc/fstab file. Since Prestoserve does not support floppy drives, it displays the error message above.

To avoid this message, you can edit /etc/fstab and delete or comment out the floppy drive entry. Look for the line:

2.6 Removing the Prestoserve Software

You can remove all of the installed Prestoserve files and changes with the -r command, using the this syntax.

# presto_chango -r

During the installation of Prestoserve, the installation script saved a copy of every file it modified in a file with .prepresto" appended to the original name. As the Prestoserve removal proceeds, the script strips all Sun Prestoserve changes from each file, and if the result is identical to the original, then the original is replaced. If differences are found, Sun Prestoserve asks for verification. If confirmed, it replaces the current version of the file with the stripped one.

The Prestoserve directory created during the original installation, referred to here as prestodir, is not removed. If you want to remove it type:

# rm -r prestodir
