perform a SVM failover using powershell

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

Re: perform a SVM failover using powershell

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

 

  1. Abort any active SnapMirrors (Invoke-NcSnapmirrorAbort)
  2. Break the relationship (Invoke-NcSnapmirrorBreak)
  3. 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. 

Re: perform a SVM failover using powershell

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 Smiley Happy

 

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

Re: perform a SVM failover using powershell

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.
