How to Replace a Faulty AutoClient System

1. If the system is currently running, use the halt command to get it to the prom monitor environment and turn it off.

2. Disconnect the faulty AutoClient system from the network.

3. Connect the replacement AutoClient system onto the network.

   The replacement AutoClient system must have the same kernel architecture as the faulty AutoClient system.

4. Start Host Manager from the Solstice Launcher on the AutoClient system's server, and select the name service, if not done already.

   See "How to Start Host Manager"for more information.

5. Select the faulty AutoClient system you wish to modify from the main window.

6. Choose Modify from the Edit menu.

   The Modify window appears with fields filled in specific to the AutoClient system you selected.

7. Modify the Ethernet address and the disk configuration to be that of the new AutoClient system.

8. Click on OK.

9. Choose Save Changes from the File menu.

10. Turn on the new system.

11. If the screen displays the > prompt instead of the ok prompt, type n and press Return.

    The screen should now display the ok prompt.

    Note -

    This step is not required for Sun-4 systems, because they do not have the ok prompt.

12. Boot the AutoClient system with the following command:

    If the AutoClient System Is A ...	Then Enter ...
    Sun4/3nn	b le()
    Sun4/1nn Sun4/2nn Sun4/4nn	b ie()
    i386	See "i386: Booting From the Network".
    All other Sun systems	boot net

13. After the AutoClient system boots, log in as root.

14. Set the AutoClient system's default boot device to the network by referring to "SPARC: How to Set Up a System to Automatically Boot From the Network".

    ---

    Note -

    This step is necessary for an AutoClient system, because it must always boot from the network. For example, an AutoClient system should automatically boot from the network after a power failure.

Example of a Command-Line Equivalent for Replacing a Faulty AutoClient System

The following command is equivalent to using Host Manager to modify the Ethernet address for an AutoClient system.

% admhostmod -e ethernet_address host_name

The following command is equivalent to using Host Manager to modify the disk configuration for an AutoClient system.

% admhostmod -x diskconf=disk_config host_name

For more information on disk configuration options, see Table 6-3.
