Introduction 5

Introduction

The Dell PowerVault Modular Disk (MD) storage arrays provide an industry

standard application programming interface (API) called the Storage

Management Initiative Specification (SMI-S). This interface enables third

party SMI-S client applications to manage MD storage arrays in a multi-

vendor Storage Area Network (SAN) environment.

SMI-enabled management applications are known as CIM clients. To allow

clients to manage a storage device, an SMI-S Provider (also referred as SMI-S

Agent or CIM Agent) is required. SMI-S Providers can be implemented as:

• A proxy interface that translates the existing API of a device to an SMI-S

compliant interface.

• A native feature of the storage device API. This implementation is

sometimes referred to as an

embedded agent

Dell MD SMI-S Provider is implemented as a proxy interface.

This

implementation is the quickest path to SMI-S compliance, but it requires that

the proxy provider and a Common Information Model Object Manager

(CIMOM) are installed on a server. A CIMOM is a CIM/WBEM infrastructure

that receives, validates, and authenticates CIM requests from the client

application. The CIMOM directs the requests to the appropriate device

provider.

The Dell SMI-S Provider, referred to as SMI-S Provider, must run on a server

on the storage network. OpenPegasus CIMOM is installed during the

installation of this SMI-S Provider.

The SMI-S Provider provides the SMI-S interface to the Dell PowerVault

Modular Disk storage array family. The provider uses the proxy CIM Agent

model and is supported on Windows and Linux platforms only. For the actual

versions of the platforms, see the support matrix for the MD storage arrays at

support.dell.com/manuals.

Installing and Uninstalling the SMI-S Provider 7

Installing and Uninstalling the SMI-S

Provider

System Requirements

The system requirements to install and run the SMI-S Provider include:

• Memory requirements—1 GB minimum (2 GB preferred).

• Connectivity requirements—Ethernet with 100BASE-T minimum

(Gigabit Ethernet preferred), TCP/IP.

• Port requirements—TCP port 5988 or TCP port 5989, or any other

available port if these ports are not available.

• Storage array password—The device credentials profile requires the storage

array password (SharedSecret) to modify operations. The SMI-S Provider

persistently tracks an instance of the SharedSecret per storage array.

Installing SMI-S Provider

For Windows

The SMI-S Provider is packaged as an installation executable file. To install

the SMI-S Provider:

Move the SMI-S Provider installation executable file on the server where

you want to install the SMI-S Provider and double-click the installation

executable icon and follow the instructions on the screen.

During installation,

ArrayHosts.txt

file opens.

Enter the

HostName

(s)

IP Address

(s)

of the MD storage array(s) to be

managed by the host in ArrayHosts.txt, save and close the file.

CAUTION: Enter only one of the two management ports' IP addresses of each

array in this file. Do not enter the IP addresses of both management ports.

Click

Finish

The SMI-S Provider is installed on your system. After installation, you can

delete the installation executable file.

8Installing and Uninstalling the SMI-S Provider

For Linux

The SMI-S Provider is packaged as an archive file.

To install the SMI-S Provider:

Move the SMI-S Provider RPM package file into the file system on the

server where you want to install SMI-S Provider.

Run the following command:

rpm -ivh <rpm package name>.rpm

NOTE: On SUSE Linux Enterprise Server platform, ensure that you set the

environment variables PEGASUS_HOME and LD_LIBRARY_PATH before

running any CLI from pegasus/bin directory (like cimcli or cimserver). Set the

environment variables to the following (assuming the /opt/dell as the default

install path)

export PEGASUS_HOME /opt/dell/pegasus

export LD_LIBRARY_PATH /opt/dell/pegasus/lib

To change the OpenPegasus CIMOM configuration, see "Configuring CIM

Server" on page 8.

Configuring CIM Server

Use the following commands to perform basic CIM server configuration

operations.

NOTE: You must restart the OpenPegasus server after executing any of the

following commands.

• To set an http port:

# cimconfig -s httpPort=<port> -p

• To set an https port:

# cimconfig -s httpsPort=<port> -p

• To enable or disable the http connection:

# cimconfig -s enableHttpConnection={true | false}

-p

• To enable or disable the https connection:

# cimconfig -s enableHttpsConnection={true |

false} -p

Installing and Uninstalling the SMI-S Provider 9

• To enable or disable authentication:

# cimconfig -s enableAuthentication={false | true}

–p

• To add a user for defining the credentials for CIM client to authenticate

with the CIM server:

# cimuser -a -u username -w password

• To remove a user:

# cimuser -r -u username -w password

• To enable or disable service location protocol (SLP):

# cimconfig -s slp={true | false} -p

If SLP is enabled, see Table 2-1 for additional settings information.

Commands are of the format

cimconfig -s <propertyName>={true|false} -p

where <propertyName> is a column heading in Table 2-1.
