WFA - Rename Node - NonInteractive mode


Hey All,


Mainly documenting this here in case anyone else runs into this. 


I was testing out a WFA command to rename a node and was getting errors about NonInteractive mode when testing the command.


Output from the command test:



20:29:20.316 INFO  [Rename Node] ### Command 'Rename Node' in 'POWER_SHELL' ###
20:29:22.863 INFO  [Rename Node] Get-WfaCredentials -Host primary_cluster
20:29:22.894 INFO  [Rename Node] Credentials successfully provided for 'primary_cluster'
20:29:22.941 INFO  [Rename Node] Connect-Controller -Type CLUSTER -Name primary_cluster -Credential System.Management.Automation.PSCredential -Vserver 
20:29:23.222 INFO  [Rename Node] Connect-NcController (with credentials) -Name primary_cluster -Timeout 60000 -ErrorAction Stop -Port 443 -SSLVersion TLSv1.2
20:29:25.097 INFO  [Rename Node] Connected to cluster node
20:29:25.113 INFO  [Rename Node] Renaming node 'test' with new name of 'test2' on Cluster 'primary_cluster'
20:29:25.191 ERROR  [Rename Node] Windows PowerShell is in NonInteractive mode. Read and Prompt functionality is not available.
20:29:25.300 ERROR  [Rename Node] Failed executing command. Exception: Windows PowerShell is in NonInteractive mode. Read and Prompt functionality is not available.



I ran the code from the Windows server itself and the error was apparent - it's trying to confirm the action:



PS C:\Program Files\netapp\wfa\posh> rename-ncnode -name primary_controller-01 -NewName test

Rename node
Are you sure you want to rename node primary_controller-01 to test?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): PS C:\Program Files\netapp\wfa\p
PS C:\Program Files\netapp\wfa\posh>



So I ended up adding '-Confirm:$false' to the command code and things work properly now.


Here's the PoSH code for the node rename if anyone needs it.  Super simple but might save someone a few minutes of work.



param (
  [parameter(Mandatory=$true, HelpMessage="Cluster IP Address")]

  [parameter(Mandatory=$true, HelpMessage="Old Node name")]

  [parameter(Mandatory=$true, HelpMessage="New Node name")]

# connect to controller
Connect-WfaCluster $Cluster

# rename the aggregate
Get-WFALogger -Info -message $("Renaming node '" + $OldNodeName + "' with new name of '" + $NewNodeName + "' on Cluster '" + $Cluster + "'")
Rename-NcNode -Name $OldNodeName -NewName $NewNodeName -Confirm:$false -ErrorAction Stop
