SPARC: How to Reset the System

Run the reset command from the ok prompt. 

ok reset

This self-test program, which runs diagnostic tests on the hardware, is executed and the system is rebooted.

SPARC: Booting a System

If a system is turned off, turning it on starts the multiuser boot sequence. The following procedures show how to boot to different run levels from the ok PROM prompt. These procedures assume that the system has been cleanly shut down, unless stated otherwise.

Use the who -r command to verify that the system is brought to the specified run level. For a description of run levels, see Chapter 11, Run Levels and Boot Files (Tasks).

SPARC: How to Boot a System to Run Level 3 (Multiuser Level)

Use this procedure to boot a system (that is currently at run level 0) to run level 3.

  1. Boot the system to run level 3. 

    ok boot

    The automatic boot procedure displays a series of startup messages, and brings the system to run level 3.

    For more information, see boot(1M).

  2. Verify that the system has booted to run level 3.

    The login prompt is displayed when the boot process has finished successfully.

    hostname console login:

SPARC: How to Boot a System to Run Level S (Single-User Level)

Use this procedure to boot a system (that is currently at run level 0) to run level S.

  1. Boot the system to run level S. 

    ok boot -s

  2. Type the superuser password when the following message is displayed.

    INIT: SINGLE USER MODE
Type Ctrl-d to proceed with normal startup,
 
(or give root password for system maintenance):  xxx

  3. Verify that the system is at run level S.

    # who -r
.       run-level S  Jun 10 15:27     3      0

  4. To bring the system up to multiuser state after you completed the system maintenance task, press Control-D.

SPARC: How to Boot a System Interactively

Use this procedure to boot a system and you need to specify an alternate kernel or /etc/system file.

  1. Boot the system interactively. 

    ok boot -a

  2. Answer the system prompts as described in the following table.

    System Prompt

    Action

    Enter filename [kernel/[sparcv9]/unix]:

    Provide the name of kernel to use for booting. Or, press Return to use the default kernel.

    Enter default directory for modules [/platform/`uname -i`/kernel /platform/`uname -m/kernel /kernel /usr/kernel]:

    Provide an alternate path for the modules directory. Or, press Return to use the default kernel modules directory.

    Name of system file [etc/system]:

    Provide the name of an alternate system file and press Return. Type /dev/null if your /etc/system file has been damaged. Or, press Return to use the default etc/system file.

    root filesystem type [ufs]:

    Press Return to use the default root (/) file system. Type UFS for local disk booting, or NFS for network booting.

    Enter physical name of root device

    [physical_device_name]:

    Provide an alternate device name and press Return. Or, press Return to use the default physical name of the root device.

  3. If you are not prompted to answer the questions in the preceding table, verify that you typed the boot -a command correctly.
