Here's a command you could throw in a workflow...
It's identical to the one in the Day-0 example workflow I posted here:
https://communities.netapp.com/docs/DOC-20088
but it avoids vol0 as your customer is looking for.
(
Using
Get-NaVol | Where-Object { $_.Name -ne "vol0" } | Set-NaVolOption -key "$OptionName" -value "$OptionValue"
instead of just
Get-NaVol | Set-NaVolOption -key "$OptionName" -value "$OptionValue"
)
Hope this helps,
Dave
