I posted a 7-mode Set ONTAP Options command as part of the Day-0 workflow example that takes a PowerShell array of option->value pairs as a parameter so you can set more than 1 option per row. The text fields in WFA 2.0 are limited to 256 characters, though. So, without any tricks, with the command I posted you could set options up to 256 characters per row.
The 2.0 version of the Day-0 workflow has some examples of using that command, and how to specify the array of options, too.
Hope this helps,
I am a developer in the WFA team and I have been trying to reproduce this issue.
I have run a workflow with a loop of a 100 commands and it worked pretty fast and without any problems.
Can you please provide me details regarding the workflow, command, WFA version...
Also a backup will be appreciated
