1 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 supplies. 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 Storage Enclosure 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 using in-band SAS connections. Terminology This document familiarizes you with the functions of the Storage Enclosure Management Software. The Storage Enclosure Management Software is comprised of two major components: • Storage Enclosure CLI (secli) - This component provides a command-line interface (CLI) used to obtain device and status information of storage enclosure components. In addition, the secli is used for firmware update of Enclosure Management Modules (EMMs) as well as hard drives and solid-state drives within the enclosure. • Storage Enclosure Monitor - This component runs continuously, monitoring and logging the status of enclosure components, including EMMs, drives, power supplies and fan modules. The document is organized into two major sections. The first section of this document describes the CLI commands required to perform certain common task within the storage enclosure. The second section is a reference to all CLI commands ordered by type. Other information you may need WARNING: See the safety and regulatory information that shipped with your system. Warranty information may be included within this document or as a separate document. NOTE: All the documents, unless specified otherwise, are available at dell.com/support/manuals. • The rack documentation included with your rack solution describes the process of installing your system into a rack. 6

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 supplies.
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 Storage Enclosure 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 using in-band SAS connections.
Terminology
This document familiarizes you with the functions of the Storage Enclosure Management Software. The
Storage Enclosure Management Software is comprised of two major components:
•
Storage Enclosure CLI (
secli
) — This component provides a command-line interface (CLI) used to
obtain device and status information of storage enclosure components. In addition, the secli is used
for firmware update of Enclosure Management Modules (EMMs) as well as hard drives and solid-state
drives within the enclosure.
•
Storage Enclosure Monitor — This component runs continuously, monitoring and logging the status
of enclosure components, including EMMs, drives, power supplies and fan modules.
The document is organized into two major sections. The first section of this document describes the CLI
commands required to perform certain common task within the storage enclosure. The second section is
a reference to all CLI commands ordered by type.

information may be included within this document or as a separate document.
