For the AFF A250 storage system, you can perform maintenance procedures on the following components.
The boot media stores a primary and secondary set of boot image files that the system uses when it boots.
The chassis is the physical enclosure housing all the controller components such as the controller/CPU unit, power supply, and I/O.
A controller consists of a board, firmware, and software. It controls the drives and implements the ONTAP functions.
You must replace a DIMM (dual in-line memory module) when a memory mismatch is present, or you have a failed DIMM.
A drive is a device that provides the physical storage media for data.
The fan cools the controller.
A Mezzanine card is a printed circuit board that plugs directly into another plug-in card.
A battery is included with the controller and preserves cached data if the AC power fails.
A power supply provides a redundant power source in a controller shelf.
Real-time clock battery
A real time clock battery preserves system date and time information if the power is off.
