Quota Management in NetApp PowerShell Toolkit broken?

w_ratzka

I'm trying to port an old NetApp PowerShell Toolkit script running on an old server that is managing our home directory quota to the current version of the NetApp PowerShell Toolkit (9.14.1.2401) on an up-to-date server.

First strange effect: Unless I specify -ZapiCall, the Get-NcQuota and Get-NcQuotaReport are useless for me, as the QuotaTarget fields come up blank. So -ZapiCall it must be, even if that interface is deprecated.

Next problem: I have a quota entry, that clearly exists:

> Get-NcQuota -Type User -Target AD\ratzka_t -Volume vol_HRZ_H -VserverContext vsrz001 -Qtree ""

QuotaType QuotaTarget Volume Qtree DiskLimit FileLimit Vserver
--------- ----------- ------ ----- --------- --------- -------
user AD\ratzka_t vol_HRZ_H 36909875 - vsrz001

But trying to remove it gives me a confusing error message:

> Remove-NcQuota -Type User -Target AD\ratzka_t -Volume vol_HRZ_H -VserverContext vsrz001 -Qtree ""
Remove-NcQuota : Group parameter neither specified nor set
At line:1 char:1
+ Remove-NcQuota -Type User -Target AD\ratzka_t -Volume vol_HRZ_H -Vser ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Remove-NcQuota], ArgumentException
+ FullyQualifiedErrorId : Group is empty,DataONTAP.C.PowerShell.SDK.Cmdlets.Quota.RemoveNcQuota

Incidentally, searching for this error message turns up a suggestion to just do REST directly.

So is there anybody out there who is successfully using the NcQuota-cmdlets?

Kind Regards,

Hi Wolfgang

There is also an "Invoke-NcCli" CmdLet that can be used as an alternative to SSH which uses the private REST CLI but I prefer to define my own functions. Anyway i did ping the PSTK developers to take a look into the issues with these CmdLet's so hopefully it gets fixed in a future release.

Hi Wolfgang,

I had a look into the issue (both using an older PSTK version which works) and the latest version (which doesn't work). I think this might be related to the REST API implementation (which the PSTK is leveraging):

I will reach out to the developers. As a workaround you can use functions in your code that leverage either REST API or the private REST CLI to invoke commands over HTTPS. Here are some examples

Create a quota using the private REST CLI:

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

I have continued looking for a solution myself and found it easier to use Invoke-NcSsh together with the volume quota policy rule commands, as this requires less "glue" and fits into the original script quite nicely. (Well, the quota in my first attempt where too generous by a factor of 1024...)

I will, however, look into your suggestions as I am not sure that we shouldn't move from PowerShell Toolkit to REST-API or REST-CLI.

Thanks a lot

Hi Wolfgang,

Note that you can also use the "Invoke-NcCli" CmdLet (which can be used as an alternative to SSH). Essentially this will invoke the private REST CLI (so if there's ever an issue using a CmdLet or a command that has no associated CmdLet then you can resort to this method). Here's an example of creating a Quota:

Connect-NcController -Name 192.168.100.2 -Credential $credential | Out-Null 
Invoke-NcCli -Command "volume quota policy rule create" -Body '{"type":  "user", "vserver":  "vserver1", "policy-name":  "default", "target":  "TESTLAB\\N2003905", "qtree":  "",  "disk-limit":  "5GB", "volume":  "cifs_data_001"}'

This might be an option for you if you prefer not to add custom functions to your code to invoke the REST API and just use native CmdLet's within the PSTK.

Hope that helps

In Rest QuotaTarget is No Rest Equivalent

quota-target

NO REST EQUIVALENT

The REST API uses one of the three separate fields instead of quota-target: users/group/qtree.

For Remove-NcQuota could you please share the debug logs with us on ng-ontap-pstk-rest DL it will help us to identify the issue more efficiently.

You can enable the debug logs using Set-NaToolkitConfiguration debug command.
