NetApp DataONTAP PowerShell Service Processor Reboot Command

I am trying to reboot the service processor on our netapp filers with the below command as part of a powershell script


$controller | ForEach-Object {

Invoke-NaSsh -Controller $_ -Command "sp reboot" -Credential $credential }


When running this command I get prompted for the following;


NOTE : If your console connection is through the SP,it will be disconnected
Do you want to reboot the SP now? (y/n) :?


Does anyone have an idea how I can confirm within the powershell script
