Not supported for REST call

reuvygroovy — Wed, 04 Jun 2025 09:48:11 GMT

We have upgraded from ONTAP 9.9.1P10 to 9.11.1P9.

We have extensively used the PowerShell Toolkit for automation. After the upgrade many command stopped working, where we received errors that the switch isn't support. We even tried downgrading the toolkit to the previous version but that didn't help against 9.11.

Here is one example, where the switch isn't supported:

New-NcVol -ExcludedFromAutobalance

An example of a switch within command which is no longer working:

Get-NcEmsMessage -StartTime

We get this error:

There was an error Get NcEmsMessage System.ArgumentException: StartTime parameter specified, which is not supported for REST call at System.Management.Automation.MshCommandRuntime.ThrowTerminatingError(ErrorRecord errorRecord) At line:526 char:19 For: $Events = Get-NcEmsMessage -StartTime $startdate | Where-Object { $_.MessageName -notin $Ignore } Reason: ArgumentException, Activity: Get-NcEmsMessage, Category: InvalidArgument

We see on the site (https://docs.netapp.com/us-en/ontap-restmap-9111/volume.html#volume-encryption-conversion-start) that some of the commands say: No REST Equivalent

But we know 100% these commands worked before the upgrade.

Has the Toolkit/REST API been limited?

Hey @reuvygroovy. If you find that you're not getting the answer in a timely manner over here in the Community, you might find some success over in the Powershell Toolkit channel in our Discord. If you'd like, you can join us here: https://netappdiscord.com

Hi,

Did you try using the -Ontapi parameter when connecting to the cluster using Connect-NcController then test the command you are having problems with? By default the latest version of the PSTK will do an ONTAP version check and if running >= ONTAP 9.6 it will attempt to use REST API's unless you explicitly tell it not to by using the -Ontapi parameter which tells the PSTK to revert to using ZAPI for CmdLet's with the context of the cluster connection. That might be a temporary solution for you but longer term ZAPI is being removed in ONTAP 9.13 so you would need to use REST API CLI pass through.

Hope that helps explain it

Hi, We need support ongoing. ZAPI is being phased out. Also, before the upgrade to 9.11, we were on 9.9.1P10 and we were able to run the command without the -Ontapi switch.
