You can boot the storage system from the storage system prompt, the CLI prompt for the remote management device, or the boot environment prompt.
You can boot the storage system from the storage system prompt, for example, toaster>.
You can also boot Data ONTAP remotely from the CLI prompt of the remote management device, for example, SP> or RLM>.
You can also boot the storage system with the following boot options from the boot environment prompt:
Boots the current Data ONTAP software release stored on the boot device (such as a PC CompactFlash card). By default, the storage system automatically boots this release if you do not select another option from the basic menu.
Boots the Data ONTAP release stored on the boot device as the primary kernel. This option overrides the firmware AUTOBOOT_FROM environment variable if it is set to a value other than PRIMARY. By default, the boot_ontap and boot_primary commands load the same kernel.
Boots the backup Data ONTAP release from the boot device. The backup release is created during the first software upgrade to preserve the kernel that shipped with the storage system. It provides a "known good" release from which you can boot the storage system if it fails to automatically boot the primary image.
Boots a Data ONTAP diagnostic kernel.
Other boot options should be used only under the direction of technical staff.
