Rebooting a System

Normally, the system reboots at power-up or after a system crash. You can reboot a system by using either the init command or the reboot command. The init 6 command asks for stop methods (either SMF or rc.d). Whereas, the reboot command does not, thereby making the reboot command a more reliable way of rebooting a system. See init(1M) and reboot(1M) for details.

    The reboot performs the following actions:

  • Restarts the kernel

  • Performs a sync operation on the disks

  • Initiates a multi-user boot.

Although the reboot command can be used by the root user at any time, in certain cases, as with the reboot of a system with multiple users, the shutdown command is used first to warn all users who are logged in to the system of the impending loss of service.
