This project is read-only.
this project has been depreciated, please get the official toolkit availiable:


PoshOnTap brings Manage OnTap to PowerShell in the form of a PowerShell Module containing over 220 Cmdlets. This project aims to bridge the management gap, and bring the power and flexibility of PowerShell to the storage administrator.


  • You must have PowerShell V2 installed in order to use this module.
  • Download PoshOnTap and run the PoshOnTap.msi, or download the for xcopy deploy.
  • Run Import-Module PoshOnTap from within powershell.

Quick Hints

  • To get a list of cmdlet in the module type: Get-Command -module PoshOnTap
  • Once your ready to look around connect to destination NetApp Filer with the Connect-NaServer cmdlet.
Connect-NaServer -Server NetApp3
The above command will attempt to connect via RPC to NetApp3 using the credssp credentials of the current Shell. You can also connect via HTTP, and HTTPS. vFiler tunneling is also supported, although that functionality hasn't been fully tested.
  • Help, Every cmdlet has Full V2 Comment based help.
  • ShouldProcess, For those of you who don't know ShouldProcess enables the administrator to explore what may happen if they were to execute a command. PoshOnTap takes ShouldProcess to a step further. When you add -whatif or -Confirm to any supported cmdlet you will get a meaningful message. For instance if you wanted to delete all snapshots on a volume named vol1, you could preview the outcome by adding whatif.
PS> Get-NaVol Vol1 | Get-NaSnapshot | Remove-NaSnapshot -Whatif
What if: Performing operation "Deleting snapshot test6 from vol0" on Target "netapp1".
What if: Performing operation "Deleting snapshot test5 from vol0" on Target "netapp1".
What if: Performing operation "Deleting snapshot test4 from vol0" on Target "netapp1".
What if: Performing operation "Deleting snapshot test3 from vol0" on Target "netapp1".

As you can see we didn't simply echo that we where deleting a snapshot. Instead we tell you what snapshot we would have deleted on what filer... a meaningful message. While this proved to be difficult at times we couldn't be happier with the outcome.
  • Has-a binding! Every cmdlet in the project makes some use of the PowerShell pipeline, and 99% of that binding is done by property name. We did this for one simple reason, we know you're not going to live in our little sandbox. By property name binding enables you to glue our functionality into anything!

What's missing

Currently we haven't implemented any cmdlets to handle:
  • NFS
  • CIFS
  • SnapVault
  • FCP
  • User/Role Management
Alas hope is not lost, the NaServer object returned by New-NaServer can be used to execute raw ZAPI calls. AKA roll your own!
$Server = New-NaServer NetApp3 -NoSSL -Credentials (Get-Credentials root)

We hope to close in on these glaring holes, but in the meantime see for more information on PowerShell and the OnTap API.


real basic present an ISCSI Lun from scratch.
Connect-NaServer Netapp1 -NoSSL
# create a new aggragate 
New-NaAggr aggr1 -DiskCount 10
# create a new Volume in our aggregate
New-NaVol vol1 -Aggregate aggr1 -size 1gb
# Create a new Lun in our new volume
New-NaLun /vol/vol1/lun1 -Size 500mb
# Create a new IGroup to map our lun
New-NaIGroup igrp0 -Type iscsi -OSType windows
# Add initiators to our IGroup
Get-NaIGroup igrp0 | Add-NaInitiator
# Map our Lun
Add-NaLunMap /vol/vol1/lun1 -IGroup igrp0 -LunID 0

Add a new RaidGroup to Aggr0 with 10 disks

Configure SnapMirror
# Connect to Snapmirror Source and Destination

$DestFiler = new-NaServer NetApp2 -NoSSL
# License Snapmirror
Add-NaLicense DFVXFJJ -server $DestFiler
