You can boot the current release or the backup release of Data ONTAP when you are at the boot environment prompt of a node.
- 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.
- At the boot environment prompt, enter one of the following commands:
The current release of Data ONTAP
The Data ONTAP primary image from the boot device
The Data ONTAP backup image from the boot device
If you are unsure about which image to use, you should use boot_ontap in the first instance.
