The NetApp E-Series 60-Drive Tray is a storage system designed for high-capacity data storage, featuring a modular architecture that allows for the replacement of individual drive drawers. This document outlines the procedure for replacing a failed drive drawer, emphasizing the importance of data protection and proper handling to prevent hardware damage.

Function Description:

The E-Series 60-Drive Tray serves as a storage enclosure for various NetApp controller-drive trays and expansion drive trays, including the E2660, E2760, E5460, E5560, E5660, and DE6600 models. Each 60-drive tray is equipped with five drive drawers, and each drawer can accommodate up to 12 drives. The system is designed to provide robust data storage, with features like Drawer Loss Protection to safeguard data during maintenance operations.

Important Technical Specifications:

Drive Capacity: Each 60-drive tray contains five drive drawers, with each drawer capable of holding up to 12 drives, totaling 60 drives per tray.
Drawer Loss Protection: The system supports Drawer Loss Protection, which allows for online replacement of drive drawers if all volumes within the drawer are protected. If not, host I/O activity must be stopped, and the tray powered off before replacement.
Service Action Allowed LED: A blue Service Action Allowed LED indicates when a drive drawer can be safely serviced, particularly when Drawer Loss Protection is active.
Cable Chains: Each drive drawer utilizes left and right cable chains that allow the drawers to slide in and out. These chains connect to vertical brackets (midplane) and horizontal brackets (drive drawer).
Lock-out Tumbler: A safety feature that prevents more than one drive drawer from being opened at a time.
Fan Canisters: The system uses fan canisters for cooling, with a requirement that at least one fan remains operational if the tray is powered on during maintenance to prevent overheating.

Usage Features:

Modular Design: The system's modular design, with individual drive drawers, facilitates easier maintenance and replacement of failed components without necessarily disrupting the entire storage system.
Online Replacement (with Drawer Loss Protection): If Drawer Loss Protection is enabled and all volumes are protected, a drive drawer can be replaced online, minimizing downtime. This is initiated by the Set Drawer Service Action Allowed Indicator CLI command.
Offline Replacement (without Drawer Loss Protection): If Drawer Loss Protection is not active for all volumes, host I/O activity must be stopped, and the tray powered off to prevent data loss during drawer replacement.
CLI Command Interface: The system utilizes a Command Line Interface (CLI) for managing service actions, such as enabling the Service Action Allowed Indicator.
Visual Indicators: The blue Service Action Allowed LED and green LEDs on the fan canisters provide visual cues for system status and safe operation.

Maintenance Features:

Required Tools: Maintenance requires antistatic protection, a replacement drive drawer, replacement left and right cable chains, an orange cable chain removal tool, a flashlight, and a permanent marker. The cable chain removal tool is specifically designed to simplify unplugging cable chain connectors in tight spaces.
Antistatic Protection: Emphasized as crucial to prevent electrostatic discharge damage to drive tray components.
Step-by-Step Procedure: The manual provides a detailed, sequential procedure for preparing, removing, installing, and attaching components, ensuring proper execution of maintenance tasks.
Data Preservation: Instructions include marking drive locations with a permanent marker before removal to ensure drives are reinstalled in their original slots, which is critical to prevent data loss.
Overheating Prevention: Strict warnings are given against removing both fan canisters simultaneously while the tray is powered on, to prevent overheating and potential equipment damage.
Cable Chain Management: Specific instructions are provided for disconnecting and reconnecting cable chains, including proper alignment and ensuring connectors are latched to prevent them from coming loose during operation.
Drive Handling: Drives must be placed on a flat, static-free surface and kept away from magnetic devices to prevent data loss and damage to drive circuitry.
Drawer Installation Guidance: The lock-out tumbler and drawer guides are highlighted to ensure correct insertion of the drive drawer, preventing damage during installation.
Post-Maintenance Verification: After replacement, steps include verifying fan operation (green LED illuminated, air flow) and confirming that the system powers on correctly.
