You can start your storage system in several ways. You can boot the storage system from the storage system prompt or boot environment prompt. You can also start the storage system remotely. You can restart your system by halting and booting it.
How to boot the storage system
The storage system automatically boots Data ONTAP from a boot device, such as a PC CompactFlash Card. The system's boot device, shipped with the current Data ONTAP release and a diagnostic kernel, contains sufficient space for an upgrade kernel.
About rebooting the storage system
Rebooting the storage system is equivalent to halting and booting the storage system. During a reboot, the contents of the storage system's NVRAM are flushed to disk, and the storage system sends a warning message to CIFS clients.
Halting the storage system
The halt command performs an orderly shutdown that flushes file system updates to disk and clears the NVRAM
Managing the storage system by using the boot menu You can use the boot menu to correct configuration problems, reset the root password, initialize disks, reset system configuration, and restore system configuration information back to the boot device.
