I am new to WFA and having trouble to setup workflow to create export rule

sp_1008 — Wed, 04 Jun 2025 12:08:28 GMT

I am setting up a WFA workflow to create NFS share and export it. I am trying to use Netapp certified WF "create export rule" but I don't see the parameter "-DisableDev" in the powershell script. I want to add this pramnter in the create export rule. Having trouble to set the parameter "-DisableDev" which will not allow to creation of devices on NFS server.

I am not sure what is the exact syntex to add this paramter in the WFA powershell script.

Any assistance on this will be a great help!

I ran into this with some other certified commands, specifially 'Create CIFS Share', that didn't support all the options.

You'll basically want to copy that command to a new one, put on your Powershell hat, add the paramter at the top, then check if that parameter exists, then keep adding onto the command variable that it's building.

Here's the code block for the Create CIFS Share' I hacked at .. parameters for 'Share Properties' and 'vscan profile' were what I added.

param (
  [parameter(Mandatory=$true, HelpMessage="Name or IP address of the cluster hosting the Storage Virtual Machine.")]
  [string]$Cluster,

  [parameter(Mandatory=$true, HelpMessage="Name of the Storage Virtual Machine in which the CIFS share will be created.")]
  [string]$Vserver,

  [parameter(Mandatory=$true, HelpMessage="File system path that is shared through this CIFS share.")]
  [string]$Path,

  [parameter(Mandatory=$true, HelpMessage="Name of the CIFS share to be created.")]
  [string]$ShareName,
 
  [parameter(Mandatory=$false, HelpMessage="A comment that gives a description of the CIFS share. CIFS clients see this description when browsing the Storage Virtual Machine's CIFS shares.")]
  [string]$Comment,

  [parameter(Mandatory=$false, HelpMessage="Share Prperties.")]
  [string]$share_properties,

  [parameter(Mandatory=$false, HelpMessage="Set Vscan Profile for Share")]
  [string]$vscanProfile
)

Get-WFALogger -Info -message $("Creating CIFS share: " + $ShareName + "at path: "+ $Path)

$command = "Add-NcCifsShare -Name " +  $ShareName + " -Path " + $Path 

if ($Comment)
{
    $command += " -Comment " + "'" + $Comment + "'"
}

if ($share_properties)
{
    $command += " -ShareProperties " + $share_properties

}

if ($vscanProfile) {
    $command +=  " -VscanProfile " + "'" + $vscanProfile + "'"
}

$command += " -VserverContext " + $Vserver

# connect to cluster
Connect-WfaCluster $Cluster

Try
{
    $result = Invoke-Expression -ErrorAction stop $command
}
Catch
{
    $ErrorMessage = $_.Exception.Message
    throw "Create CIFS share failed. Reason : " + $ErrorMessage 
}
if ($result.Status -eq "failed")
 {
    throw "Create CIFS share failed. Reason : " + $result.ErrorMessage
 }

Hi,

The certified content that comes with WFA may not enable all parameters that can be set via the PSTK\ZAPI. You can use it as an example to develop your own commands if you require additional parameters to be set. Here is an example for you:

Param(
   [Parameter(Mandatory=$True, HelpMessage="The Cluster name or IP address")]

Hi,

Also as an example for you (related to creating an export rule), if your cluster is running ONTAP 9.6 or greater, you can invoke the REST API rather than use the PSTK however not all parameters that are currently available in the PSTK\ZAPI are currently available using the REST API however it's likely they will be supported in a future release. Hope this is a useful example:

   [Parameter(Mandatory=$True, HelpMessage="The Cluster name or IP Address")]

Re: I am new to WFA and having trouble to setup workflow to create export rule

mbeattie — Tue, 19 Nov 2019 00:37:52 GMT

Hi,

Another option might be to use an alternative to WFA such as Ansible:

https://www.ansible.com/

However regardless of which orchestration application you choose for your enviroment, inevitably you may encounter a similar issue in that it may not support each and every parameter that is available via the CLI\ZAPI (EG for export rules "DisableDev") as you've discovered with the certified content in WFA.

https://docs.ansible.com/ansible/latest/modules/na_ontap_export_policy_rule_module.html

In that instance can resort to using a CLI command if you wanted to include a parameter not available within the ansible module:

https://docs.ansible.com/ansible/latest/modules/na_ontap_command_module.html

In WFA you can use either "Invoke-NcSsh" within your command or preferably "Invoke-NcSystemApi" or write your own code based on the PowerShell CmdLet. See "Get-Help New-NcExportPolicy -Full"

Please let me know if you have any questions?

Thank you so much for your quick response yesterday! I really appreciate it.

I pasted script as below. The export rule powershell script is working fine except the -DisableDev parameter which is highlghted in RED in below script.

when I tested the scirpt I got below error. I tried with null vlaue too instead "true" but same error message.

Can you pelase look into this and advise?

}

The issue is resolved now. No need to give "true" or "false" after -DisableDev

If($DisableDev){

[String]$command += "-DisableDev "

Re: I am new to WFA and having trouble to setup workflow to create export rule

mbeattie — Tue, 19 Nov 2019 22:22:24 GMT

Hi,

Good to hear you got it working, that's correct the "-DisableDev" parameter does not require a boolean value. Whilst the input parameter in the command is a boolean:

   [Parameter(Mandatory=$False, HelpMessage="If specified, the NFS server will not allow creation of devices")]
   [Bool]$DisableDev,

The command expression that is set adds the parameter as a flag without a value:

If($DisableDev){
   [String]$command += "-DisableDev "
}

Glad you got it working, hope the example code was useful
