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 physical disks accessed through EMMs (Enclosure Management Modules) is

called a storage enclosure. A storage enclosure includes various hardware components, such as physical

disks, EMMs, fans, and power supply units (PSUs).

One or more host servers attached to the storage enclosure can access the data on the storage

enclosure. You can also establish multiple physical paths between the hosts and the storage enclosure so

that loss of any single path (for example, through failure of a host server port) does not result in loss of

access to data on the storage enclosure.

The storage enclosure is managed by the Server Hardware Management software running on a host

server. On the host server system, the management software and the storage enclosure communicate

management requests and event information by using in-band SAS connections.

Terminology

This document familiarizes you with the functions of the Server Hardware Management software. The

Server Hardware Management Software is comprised of two major components:

• Server Hardware Manager CLI (shmli) — This component provides a command-line interface (CLI)

used to obtain device and status information of storage and hardware components. In addition, you

can use the shmcli for firmware updates of Enclosure Management Modules (EMMs) and hard disk

drives (HDDs) and solid-state drives (SSDs) within the enclosure and system drives.

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

storage components, including enclosures, adapters, HBAs, EMMs, drives, and EMM components

(fans, power supplies, temperature sensors, and more.

The document is organized into two major sections. The first section of this document describes the CLI

commands required to perform certain common task . The second section is a reference to all CLI

commands ordered by type.
