Using Fast Reboot (Task Map)

Task
Description
For Instructions
Initiate a fast reboot of a SPARC based system.
Use the reboot command with the -f option to initiate a fast reboot of the system.
Initiate a fast reboot of an x86 based system.
Because Fast Reboot is the default boot mode in this release, you can use either the reboot or the init 6 command to initiate a fast reboot of the system.
Initiate a fast reboot of an x86 based system to a boot entry other than the default.
To reboot to a specific GRUB boot entry, use the reboot n command, where n is the number of the BE that you want to boot.
Initiate a fast reboot of an x86 based system by specifying an alternate BE.
You can fast reboot an x86 based system to an alternate BE by specifying the BE with the reboot command.
Perform a slow reboot of a system.
Use the reboot command with -p option to perform a slow reboot of the system.
Configure the default behavior for the Fast Reboot feature on the SPARC or x86 platform, and the Panic Fast Reboot feature on the x86 platform.
On the SPARC platform, Fast Reboot behavior is disabled by default. You can configure the boot-config service to perform a fast reboot of a SPARC based system by default.

On the x86 platform, Fast Reboot and Panic Fast Reboot features are enabled on your system by default and are managed by the boot-config service. You can optionally disable either or both of these features.

Debug an early panic that might occur on an x86 based system.
Because the boot-config service has dependencies on the multiuser milestone, early panics on a system can occur. To debug possible early panics on the x86 platform, you can patch the global fastreboot_onpanic variable in the /etc/system file.
Troubleshoot conditions that might prevent the Fast Reboot feature from working.
Under certain conditions, the fast reboot capability on the x86 platform does not work as expected. In some situations, a workaround is available.
