Get-NcQosPolicy in PoSH Tools V4 (3.3) NOT working - Depreciated for Get-NcQosPolicyGroup or Broken?

[ Edited ]

All,

      Get-NcQosPolicy does not work in this version against 8.3.1 GA. I am in need of this for a WFA script urgently. Any help would be greatly appreciated. CDoT OnTap Dev Team - Where is this API? How did it get removed from 8.3.1 GA?!?

 

PS C:\temp\POSH> Get-NcQosPolicy
Get-NcQosPolicy : Unable to find API: qos-policy-get-iter

In CDoT:

14 entries were displayed.

 

It seems this API really does NOT exist? Is there another API to use in it's place? If so, is it possible to manually redirect to another API from powershell commands that I am unaware of? That's a little shocking the entire API is not there.

 

In the PowerShell Modules Source Code for the DLL, I do see where to change it, however, I dont think the API even exists in CDoT. Senior Dev's??

Hi Noel,

 

Looking at the CmdLet help it does state it is unavailable from ONTAP 8.2...

 

PS C\> Get-Help Get-NcQosPolicy

DESCRIPTION
    Get a list of policies.

    This cmdlet is not available for Data ONTAP 8.2 and up.

 

Have you considered using the "Invoke-NcSsh" or "Invoke-NcSystemApi" CmdLet's as a workaround? In the intermin I'll have a look in the SDK and see if i can come up with a solution for you.

Ref not being supported after 8.2, not sure how i missed that... it would seem that we now need to use *-Get-NcQosPolicyGroup.

 

PS C:\POSH> New-NcQosPolicyGroup -Name Test -Vserver SVM01 -MaxThroughput 47Mbs

PolicyGroup MaxThroughput PolicyGroupClass Vserver
----------- ------------- ---------------- -------
Test 47MB/s user_defined SVM01

 

The Help file should perhaps state what to use in it's place post 8.2 if the API is depreciated.

 

I would also be interested to see your other solutions as well. Feel free to email me internally as well  (noela) or add me to jabber.

Hi Noel,

 

The command is "qos policy-group create" EG:

 

cluster1> qos policy-group create -policy-group policy1 -vserver vserver1 -max-throughput 10GB

 

The cmdlet is "Get-NcQosPolicyGroup" EG:


PS C:\> Get-NcQosPolicyGroup -Vserver vserver

PolicyGroup                                          MaxThroughput PolicyGroupClass     Vserver
-----------                                          ------------- ----------------     -------
policy1                                              10GB/s        user_defined         vserver1

 

Assume you need WFA command to select a policy policy group to apply to a vserver?

Hi Noel,

 

Yes the help file should probably be updated...just FYI there is an easy method to determine which cmdlets are available (or unavailable) by using the Get-NcCommand CmdLet. EG from an 8.3 simulator:

 

PS C\> get-nccommand -ListUnavailable -Category qos

Update-NcQosPolicyReadAhead         qos             {cluster}            {qos-policy-read-ahead-modify-iter, qos-settings-read-ahead-modify-iter}


PS C:\> get-nccommand -ListAvailable -Category qos

New-NcQosPolicyGroup                qos             {cluster}            {qos-policy-group-create}

Update-NcQosWorkload                qos             {cluster}            {qos-workload-modify-iter}

 

This is useful to quick show which API the cmdlet's are associated with and what has been depreciated.
