Storage Center Snapin Utility

The Storage Center Snapin Utility module provides a library of common functions. The utility module was developed using

PowerShell scripting.

NOTE: The Storage Center PowerShell Snapin must be added to the current PowerShell session to use the functions

provided by the utility.

Table 3. Snapin Utility Commands

Command Description

Get-CMLDiskSignature Retrieves the disk signatures of all disks or the disk specied in the index

parameter.

Get-CMLDuplicateDiskSignature Returns groups of disks with identical signatures. This duplication can occur

when a view volume for a clustered shared volume (CSV) is mounted to a server.

Windows will not update the signature for a CSV.

Set-CMLDiskSignature Sets the disk signature of the disk specied by the index parameter.

Set-CMLVolumeSignature Sets the disk signature for a specied volume by mapping the volume on the

computer identied by the ComputerName parameter, changing the signature

and removing the mapping. This feature is particularly useful for automating the

process of xing the disk collision issue when attempting to mount the view

volume of a CSV on a cluster node. To avoid a collision, the

ComputerName

parameter must refer to a computer that is not a node in the cluster. When this

function completes successfully, the view volume can then be mapped to a node

in the cluster without a disk signature collision.

Formatting and Exporting Command Output

Windows PowerShell provides commands that can either format the way information appears in the console or export information to

an xml, csv, or text le. These commands accept the output of other commands as input from the pipeline.

Format Command Output in the Console

By default, Dell Storage Center Command Set cmdlets print information to the console in a table format. The Format-List command

formats information as a list. For example, the following command displays a list of all properties for a Storage Center volume named

MyVolume:

Get-SCVolume -Name MyVolume|Format-List

For more information about displaying information on the console, type the following command:

Get-Help about_display

Export Command Output to a File

Command output can be stored in standard le formats. The following examples show how to save the information of a Storage

Center volume named MyVolume as an xml, csv, or txt le.

To save information in an xml le:

Get-SCVolume -Name MyVolume|Export-Clixml -path “C:\volumeInformation\MyVolume.xml”
