Stop-NcSis : This operation is not permitted on a Vserver that is configured as the destination for identity discard Vserver DR.

I am trying to run Stop-NcSis but getting the above error. 

Please refer to the screenshot attached.

Also tried below cmd:

Invoke-NcSsh -Command 'set -privilege diag; vserver config override -command "vol efficiency stop -vserver test_DR -vol source"'

Error: unexpected argument "efficiency"  - please refer to screenshot.

I'm not sure about the second one, but for the first one, have you tried this KB? This operation is not permitted on a Vserver that is configured as the destination - NetApp Knowledge Base

Hi @ChanceBingen Thank you for your reply. 

I am actually trying to write a script for disabling Sis on SVM-DR volumes.

Problem: Whenever the SVM DR relationship is broken and resynced, SIS will be re-enabled on all the DP Volumes on the DR Cluster. 

There are several DP volumes, which Sis needs to be disabled.

Tagging in @tansley for his input.

Can you help us understand why you want a DP volume to not be deduplicated? 

[Mohammed_Salman]

SIS job triggers automatically after each SnapMirror operation (15 mins as per config) and cause Disk Utilization Overhead and Performance Spikes.

Also, already Sis operation is enabled in the volumes of prod cluster which then snapmirrors to the DR Cluster.

I see. That's good info. Unfortunately, I'm not sure you can actually do what you want to do. Normally, a SnapMirror destination inherits most of the attributes of the source.

What I would really recommend is to open a support case and get to the root of the problem of why the scans are hitting your disks so hard.

I am not sure...I can execute the override command on the CLI directly, so the string of the command "vol efficiency stop -vserver xxxx" should work fine. I am not familiar with our powershell tools, so not sure if this would be an issue in the PS script/command.

[Mohammed_Salman]

Since vserver config override cmd is a Diag mode cmd, PS cmdlt Stop-NcSis doesn't work on diag level. I am looking for a PS cmdlt to work on Diag mode to stop Sis operation.

[Mohammed_Salman]

I require a equivalent diag mode cmdlet of Stop-NcSis. Any NetApp PowerShell tool kits expertise?
