Which two Hitachi Dynamic Link Manager documents provide detailed information of supported Fibre Channel HBA drivers? (Choose two.)

Question

Options

• AHitachi Engineering Change Notice (ECN)
• BHitachi Dynamic Link Manager Release Notes
• CHitachi Dynamic Link Manager Concepts and Planning Guide
• DHitachi Dynamic Link Manager for Operating Systems User's Guide

Explanation

B and D are the correct answers. The Hitachi Dynamic Link Manager Release Notes documents newly supported and deprecated Fibre Channel HBA drivers for each software version, making it essential for up-to-date compatibility information. The Hitachi Dynamic Link Manager for Operating Systems User's Guide provides comprehensive technical details including supported HBA models, driver versions, and OS-specific configuration requirements.

Why the distractors are wrong: Option A (Engineering Change Notice) is a hardware-focused document used to communicate product modifications or corrections - it is not a reference for driver support lists. Option C (Concepts and Planning Guide) covers architectural concepts, design considerations, and capacity planning, not granular driver compatibility details.

Memory tip: Think "Release + Reference" - the Release Notes tell you what's new or changed, and the User's Guide is your detailed reference for what's supported. Both together give you the full HBA driver picture; the other two documents serve planning and change-management purposes instead.
