Maintain the hardware of your AFF C30 or AFF C60 storage system to ensure long-term reliability and optimal performance. Perform regular maintenance tasks such as replacing faulty components, as this helps prevent downtime and data loss.
The procedures in this section assume that the AFF C30 or AFF C60 storage system has already been deployed as a storage node in the ONTAP environment.
System components
For the AFF C30 and AFF C60 storage systems, you can perform maintenance procedures on the following components.
The boot media stores a primary and secondary set of ONTAP image files that the storage system uses to boot. During automated recovery, the system retrieves the boot image from the partner node and automatically runs the appropriate boot menu option to install the image on your replacement boot media. The automated boot media recovery process is supported only in ONTAP 9.17.1 and later. If your storage system is running an earlier version of ONTAP, use the manual boot recovery procedure. |

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 runs the ONTAP operating system software. |
|
A dual in-line memory module (DIMM) is a type of computer memory. They are installed to add system memory to a controller motherboard. |
|
A drive is a device that provides the physical storage needed for data. |
|
A fan cools the controller and drives. |
|
The I/O module (Input/Output module) is a hardware component that acts as an intermediary between the controller and various devices or systems that need to exchange data with the controller. |
|
The non-volatile memory (NV) battery is responsible for providing power to the NVMEM components while data in-flight is being destaged to flash memory after a power loss. |
|
A power supply provides a redundant power source in a controller. |
|
A real-time clock battery preserves system date and time information if the power is off. |
