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.

The Server Hardware Manager Command Line Interface (SHM CLI) 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 hard disk drives (HDDs) within the enclosure. You can also use SHM CLI to update firmware on the MD1400/MD1420/ME484 enclosure EMMs.
