Comparing Aggregate Options Across All Aggregates in a Cluster

The following script will collect all the aggregate options of all the aggregates in a cluster, and output into a CSV, so you can compare. Simply run in PowerShell as PS>

.\Compare-AggrOptions.ps1

An example of the CSV output is below:

The Script

Copy into a text editor and save as Compare-AggrOptions.ps1.

Param(

  [Parameter(Mandatory=$true)][String]$Cluster,

  [String]$ClusterUserName,

  [String]$ClusterPassword

)

## GENERIC: DISPLAY FUNCTION

Function Wr{Param([String]$Echo = "",[String]$Ink = "WHITE"); Write-Host $Echo -ForegroundColor $Ink}

## GENERIC: LOAD THE DATA ONTAP PSTK

If(Get-Module DataONTAP){ Wr "Loaded DataONTAP PSTK" GREEN }

else{ Wr "Failed to load DataONTAP PSTK!" RED; EXIT }

## GENERIC: CONNECT TO CLUSTER

If($ClusterUserName -and $ClusterPassword){

}

else{ Wr "Failed to connnect to $Cluster!" RED; EXIT }

## CREATE CSV OF AGGREGATES AND AGGREGATE OPTIONS

$AggrAttr = get-ncaggr -Template

[System.Array]$Aggrs = (Get-NcAggr -Attributes $AggrAttr).Name

$OptionNames = (Get-NcAggrOption $Aggrs[0]).Name

[System.Array]$CSV = @()

$Aggrs | Foreach {

  $aggrOpts = Get-NcAggrOption $_

  $O = New-Object PSObject

  Add-Member -InputObject $O -MemberType NoteProperty -Name "Aggregate" -Value $_

  Foreach ($Option in $OptionNames){

    [String]$Value = ($aggrOpts | Where{$_.Name -eq $Option}).Value

    Add-Member -InputObject $O -MemberType NoteProperty -Name $Option -Value $Value

  }

  $CSV += $O

}

$CSV | Where-Object {$_} | Export-CSV -Path "AggrOptions.CSV" -NoTypeInformation
