Shutting Down and Booting a System for Recovery Purposes

    In the following instances, you must first shut down a system to analyze or troubleshoot booting and other system problems.

  • Troubleshoot error messages when the system boots.

  • Stop the system to attempt recovery.

  • Boot a system for recovery purposes.

  • Force a crash dump and reboot of the system.

  • Boot the system with the kernel debugger.

You might need to boot the system for recovery purposes.

    The following are some of the more common error and recovery scenarios:

  • Boot from the installation media or from an AI server on the network to recover from a problem that is preventing the system from booting or to recover from a lost root password. This method requires you to mount the boot environment after importing the root pool.

  • x86 only: Resolve a boot configuration problem by importing the root pool. If a problem with the file exists, you do not have to mount the boot environment, just import the root pool, which automatically mounts the rpool file system that contains the boot-related components.
