Booting ONTAP at the boot environment prompt

You can boot the current release or the backup release of ONTAP when you are at the boot environment prompt of a node.

1. Access the boot environment prompt from the storage system prompt by using the system node halt command.
   The storage system console displays the boot environment prompt.
2. At the boot environment prompt, enter one of the following commands:

   To boot...	Enter...
   The current release of ONTAP	boot_ontap
   The ONTAP primary image from the boot device	boot_primary
   The ONTAP backup image from the boot device	boot_backup

   If you are unsure about which image to use, you should use boot_ontap in the first instance.
