perform a SVM failover using powershell

tchuise92 — Wed, 04 Jun 2025 15:08:32 GMT

Good Morning everyone,

I am looking forward to configure a failover to an SVM-DR using powershell, I would like to know if somebody did it in the past even with python.

Thank you

Generally speaking, doing SVM failover is just like breaking any other SnapMirror relationship...

Abort any active SnapMirrors (Invoke-NcSnapmirrorAbort)
Break the relationship (Invoke-NcSnapmirrorBreak)
Activate the DR site (Start-NcVserver)

You'll want to add some checks and validations, but more or less, just follow the PSTK equivalent of the commands in the documentation.

Thank you for you insight, I end up using WFA but it seems like the pack needs some adjustment to fit in my environment.

We are finally getting around to doing this and would like to do with in powershell / WFA, but I have a question..

It seems when I try to break the svm-dr relationship for example from powershell

get-ncsnapmirror -vserver testvserver | ? {$_.destinationlocation -eq "testvserver:"} | invoke-ncsnapmirrorbreak it comes back with the following errors

Invoke-NcSnapmirrorBreak : Cannot bind argument to parameter 'DestinationVolume' because it is null.

with SVM you have to break the top relationship only so it's testverserver: (notice with 🙂

I'm sure it's something simple, If anyone can assist that would be great.

And andy what i'm noticing is if you have SVM-DR the pipeline command doens't work

so for example

get-ncsnapmirror -vserver testvserver | invoke-ncsnapmirrorupdate or any pipeline.

Perhaps this is a bug

Sorry to latch onto an old thread.
