Guided Maintenance Overview

As a feature of Oracle FS System Manager (GUI), Guided Maintenance presents you with a sequence of dialogs that guides you through the process of replacing field replaceable units (FRUs) and customer replaceable units (CRUs). Prompt replacement of failed FRUs and CRUs helps maintain system reliability.

Guided Maintenance supports the identification and replacement of FRUs and CRUs for Controllers and Drive Enclosures. Guided Maintenance performs the following functions to help you replace FRUs and CRUs:

Determines the status of the hardware based on events and diagnostics to accurately reflect the sate of the system.
Identifies the affected Controller or Drive Enclosure. During the identify process, Guided Maintenance issues a command to light the LEDs on the affected chassis.

If you are replacing a component on a Drive Enclosure, the following LEDs flash:
Drive

Flashes the Locate LED on the Drive Enclosure chassis and the Fault LED on the selected drive.

Power cooling module

Flashes the Locate LED on the Drive Enclosure chassis and the Fan Fail LED on the selected power cooling module.

I/O module

Flashes the Locate LED on the Drive Enclosure chassis and the Fault/Locate LED on the selected I/O module.

If you are replacing a component on the Controller, the following LEDs flash:
Energy Storage Module (ESM)

Flashes the Locate LED on the front of the Controller chassis, the Status LED on the back of the Controller chassis, and the Ready to Remove LED on the ESM.

All of the remaining Controller components

Flashes the Locate LED on the Controller chassis and the Status LED on the back of the Controller chassis.

During reverse identify, Guided Maintenance issues a command to light the LEDs on all of the chassis except for the affected chassis.
Prepares the Oracle FS System for component replacement. For FRUs and CRUs that require you to bring the chassis offline, Guided Maintenance issues commands to redirect activity from a failed component to a redundant component and then brings the chassis offline.
Displays replacement procedures for the failed FRU or CRU. For hot-serviceable FRUs and CRUs, Guided Maintenance presents a sequence of dialogs with the replacement steps. For FRUs or CRUs that require you to bring the chassis offline, Guided Maintenance provides a link to documentation containing the replacement steps.

Note: Only administrator accounts set up with support role privileges can access Guided Maintenance to replace FRUs.

Providing accurate system status and replacing FRUs and CRUs are complex operations that involve many lower level components within the system. The Oracle FS System is designed to be maintained without requiring support from Oracle Customer Support.

Each FRU and CRU has its own diagnostics, which are called by the Pilot to verify that a FRU or CRU is accessible and functioning properly. The diagnostics are primarily used to verify FRUs and CRUs that have been added or replaced. The system also tracks parts that have failed and have been removed to prevent re-insertion of failed components. Diagnostics run automatically when you replace a FRU or CRU.
