Making a WFA Command fail, when an error is detected when Command is run within a WFA Workflow

RickStratton — Wed, 04 Jun 2025 13:45:15 GMT

Looking for best/recommended way to get a WFA command to fail, when executed in a workflow, and some part of the PowerShell code within the command errors out. I am using PowerShell in my WFA commands, and I use try/throw/catch setup for issuing commands to a non-netapp storage device, and analyze the return from the storage system, and I have seen times when I get an error, but the WFA command reports back to the calling WFA Workflow, that the command completed succesfully.

I am a Powershell novice, so I suspect it's something I'm doing wrong within my PowerShell script.

Here is an example output from a WFA command when run within a WFA Workflow:

15:18:58.019 INFO [IBM Start or Stop vdisk RC Relationship] ### Command 'IBM Start or Stop vdisk RC Relationship' in 'POWER_SHELL' ###

-ErrorAction Stop is used frequently in WFA commands to stop the command execution in case of failure.

for e.g.

# Check if iGroup exists
Get-NaIgroup -Names $IgroupName -ErrorAction Stop
