Connect to your FAS / N-Series

Spin up your PowerShell. do the import-module DataONTAP and then do this:

$FilerName = "Name"

$narootpasswd = "p@ssword"

################################

$password = ConvertTo-SecureString "p@ssword" -AsPlainText -Force

$Cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "root",$password

$Filer = Connect-NaController $FilerName -Credential $Cred

There are a bunch of ways but this is easiest for me.
