2 PowerShell Extension

The OME CLI infrastructure is an extension to the PowerShell command shell. Windows PowerShell is an

interactive prompt and scripting environment that can be used independently, or in combination, and is used

by a system administrator. Unlike most shells, which accept and return text, Windows PowerShell is built on

top of the .NET Framework Common Language Runtime (CLR) and the .NET Framework and accepts and

returns .NET Framework objects. Many system administrators are familiar with PowerShell commands and

feel very comfortable using PowerShell’s infrastructure; common practices and WRT-defining commands

make CLI functionality of the OME much easier to adopt.

2.1 Authentication

CLI authentication uses the same methodology as the OME console. A single sign-on is used to access the

OME console and the CLI commands can only be run by a user who is a member of the OMEAdministrators

group. Note that the CLI infrastructure is available on the management station only. The CLI capability is not

available remotely.

2.2 Discovery or inventory task control through CLI syntax

From the PowerShell CLI, you can use three commands:

• Add <command>

• Remove <command>

• Set <command>

These three are the approved PowerShell command verbs that must prefix any new commands. The

following conventions are used in the following paragraphs:

• […]: an optional value - <…>: user provided input - ‘|’ logical „or‟.

o –Range <name> | -RangeList <rangeList.xml>: you can only provide the -Range or

-RangeList switch on the command line but not both.

2.3 Discovery configuration profile template

Several discovery configuration range or discovery configuration group commands require a template that

defines the various parameters and the associated protocol values. This template can be individually modified

and submitted as part of the CLI argument input parameter. The input parameter is consistent for all the

commands that create discovery configuration ranges or groups, and it is Profile <profile.xml file>. The

template is given here:

</ICMPConfig>
