Viewing and handling alarms is the most critical daily maintenance task for a storage administrator. Alarms are the primary mechanism for the storage system to report faults, potential risks, and performance degradation. Daily monitoring and prompt handling of these alarms are essential for maintaining system stability, ensuring data integrity, and preventing service disruptions. This proactive and reactive process allows administrators to address issues before they escalate into major outages, making it a fundamental part of daily operations.

B. Inspection storage equipment: A thorough physical inspection of hardware components like indicators, fans, and cables is typically scheduled on a weekly or monthly basis, not daily.

C. Check the computer room environment: While crucial, monitoring the data center's temperature and humidity is usually the daily responsibility of the facilities team, with storage systems generating alarms if thresholds are breached.

D. Check the internal environment of the rack: This is a subset of a physical hardware inspection and is generally performed weekly, not as a standalone daily task unless an alarm indicates a specific rack-level issue.

1. Huawei Enterprise Support Documentation: The OceanStor 5300 V3 Storage System V300R006 Routine Maintenance Guide

in Chapter 2

"Routine Maintenance"

Table 2-1 "Routine maintenance items and period"

explicitly lists "Checking alarms" as a Daily task. It lists "Checking the running status of hardware" and "Checking the storage system environment" as Weekly tasks. This directly supports that alarm management is the designated daily activity over physical or environmental inspections.

2. Huawei HCIA-Storage Courseware: The official HCIA-Storage curriculum materials consistently emphasize the importance of routine maintenance. In the modules covering storage system operations and maintenance (O&M)

daily tasks are defined to include checking the alarm list on the management interface (e.g.

DeviceManager) as the first and most important step to assess system health. (Reference: HCIA-Storage V5.0 Training Material
