Incorrect credentials after making connection multiple controllers

Daniel_Maryuma

Hi guys,

Just trying to use Get-NcSnapmirror on multiple controllers. i tried

$nc1 = connect-NcController -name xxx ...

$nc2 = connect-NcController -name yyy ...

 

When i try "Get-NcSnapmirror -Controller $nc2" i get incorrect credentials. and without -Controllers it works but i must use it  because i script resync svm-dr so i need to connect to both controllers in the same script.

 

Thanks

What version of PowerShell and the PSTK are you using? I'm not able to replicate the issue on the couple of different machines I tried it on, running PSTK 9.8.0 and PowerShell 5.1.

Hi Daniel_Maryuma,

 

I was able to replicate the issue, which indeed is due to the stored credentials only being active in memory for a single controller at a time. The solution for this would be to set a credential variable for each controller and specify the credential variable in the connect variable.

 

See the example below that I tested in our lab system using PSTK 9.8:

 

PS LAB> $creds_nc1 = Get-Credential -message 'Please provide password for nc1'
PS LAB> $creds_nc2 = Get-Credential -message 'Please provide password for nc2'
PS LAB> $nc1 = Connect-NcController lab-cluster1 -Credential $creds_nc1
PS LAB> $nc2 = Connect-NcController lab-cluster2 -Credential $creds_nc2
PS LAB> get-ncsnapmirror -controller $nc1
