Accelerating the Reboot Process

The Fast Reboot feature of Oracle Solaris is supported on both SPARC and x86 platforms. The Fast Reboot feature behaves differently on SPARC based systems than it does on an x86 based systems. On x86 based systems, Fast Reboot is the default. On SPARC based systems, the behavior is supported, but to initiate a fast reboot of a system, you must specify the -f option with the reboot command.

On a SPARC based system, using the -f option with the reboot command accelerates the boot process and skips certain POST tests. On an x86 based system, the feature is enabled by default, which means you do not have to use the -f option with the reboot command to initiate a fast reboot of the system.


Note - Fast reboot on SPARC is applicable only to certain system types. On sun4v systems, fast reboot is unnecessary because the reboot is actually a hypervisor restart that does not involve POST.


The Fast Reboot feature is implemented through the boot configuration SMF service, svc:/system/boot-config. This service provides a means for setting or changing default boot configuration properties. When the config/fastreboot_default property is set to true, the system automatically performs a fast reboot, without the need to use the reboot -f command. By default, this property is set to false on SPARC platforms. For instructions on making a fast reboot the default behavior on a SPARC based system, see Changing the Default Behavior of the Fast Reboot Feature.


Note - On SPARC based systems the boot-config service also requires the solaris.system.shutdown authorization as the action_authorization and value_authorization.


How to Initiate a Fast Reboot of a SPARC Based System

Use the following procedure to initiate a fast reboot of a SPARC based system when the config/fastreboot_default property of the boot-config service is set to false, which is the default behavior. To change the default behavior of the Fast Reboot feature so that a fast reboot is automatically initiated when the system reboots, see Changing the Default Behavior of the Fast Reboot Feature.

  1. Become the root role.
  2. Initiate a fast reboot of the system by typing the following command:
    # reboot -f

How to Initiate a Fast Reboot of an x86 Based System


Note - In this Oracle Solaris release, Fast Reboot is the default operating mode on x86 based systems. Previously, to initiate a fast reboot of an x86 based system, you needed to specify the -f option with the reboot command to initiate a fast reboot of the system. You no longer need to specify this option.


  1. Become the root role.
  2. To initiate a fast reboot of the system, type either of the following commands:
    # reboot
    # init 6

Changing the Default Behavior of the Fast Reboot Feature

The config/fastreboot_default property of the boot-config service enables an automatic fast reboot of the system when either the reboot or the init 6 command is used. When the config/fastreboot_default property is set to true, the system automatically performs a fast reboot, without the need to use the reboot -f command. By default, this property's value is set to false on a SPARC based system and true on an x86 based system.

To configure the properties that are part of the boot-config service use the svccfg and svcadm commands.

For example, to set the property's value to true (enabled) on a SPARC based system, type the following commands:

# svccfg -s "system/boot-config:default" setprop config/fastreboot_default=true
# svcadm refresh svc:/system/boot-config:default

Setting the property's value to true enables the fast reboot process, which bypasses certain POST tests. When this property is set to true, you do not have to use the -f option with the reboot command to initiate a fast reboot of the system.

For information about managing the boot configuration service through SMF, see the svcadm(1M) and svccfg(1M) man pages.

Initiating a Standard Reboot of a System That Has Fast Reboot Enabled

To reboot a system that has the Fast Reboot feature enabled, without having to reconfigure the properties of the boot-config service, use the -p option with the reboot command, as follows:

# reboot -p
