Introduction

CAUTION: See the Safety, Environmental, and Regulatory Information document for important safety information

before following any procedures listed in this document.

An enclosure containing hard drives accessed through Enclosure Management Modules (EMMs) is called a storage enclosure. A storage

enclosure includes various hardware components, such as hard drives, EMMs, fans, and power supply units (PSUs).

One or more host servers that are attached to the storage enclosure can access the data on the storage enclosure. Multiple physical

paths can be established between the hosts and storage enclosure. The multiple paths prevent the loss of any single path from resulting in

loss of access to data on the storage enclosure.

The Server Hardware Manager software on a host server manages the storage enclosure that is attached to the host. On the host server,

the management software and the storage enclosure communicate management requests and event information by using in-band SAS

connections.

Terminology

This document describes the functions of the Server Hardware Management software. The Server Hardware Management Software

consists of two major components:

• Server Hardware Manager Command Line Interface (SHM CLI)—This component provides a CLI used to obtain device and status

information of storage and hardware components. You can use the SHM CLI for firmware updates of Enclosure Management Modules

(EMMs), hard disk drives (HDDs), and solid-state drives (SSDs) within the enclosure. You can also use the SHM CLI to update the

firmware of drives located in the host system.

• Server Hardware Monitor—This component runs continuously, monitoring and logging the status of storage components. The

monitored storage components include enclosures, adapters, HBAs, EMMs, drives, and EMM components (such a fans, PSUs, and

temperature sensors).

The document is organized into two major sections. The first section describes the CLI commands that are required to perform certain

common tasks . The second section is a reference to all CLI commands ordered by command type.
