Replacing a boot device in a system running Data ONTAP
7-Mode
Replacing a boot device in a 7-Mode system involves shutting down the node,
removing the old boot device, and transferring the system files to the new boot
device.
Shutting down a node
When replacing the boot device in a system running Data ONTAP 7-Mode, you

then remove the power cords from the power supplies.
If you are replacing a device in a single-enclosure HA pair, do not remove
power from the enclosure.
