  • ONTAP 9
  • Powershell Toolkit

Issue

  • After an ONTAP upgrade, the size returned by the powershell toolkit when running Get-NcVolSize is 1024 times bigger than the actual volume size:
  • Powershell command with debug shows that, while ONTAP returns the correct value, the toolkit multiplies that value to 1024
