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 Dell Storage PowerTools Server Hardware Manager (SHM)
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 SHM software. The 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. Also, the secli is used for
firmware update of Enclosure Management Modules (EMMs) and hard drives and solid-state drives
(SSDs) within the enclosure.
•
Server Hardware Manager Monitor — This component runs continuously, monitoring and logging the
status of enclosure components, including EMMs, drives, PSUs, 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.
