Get-NaCifsSession : Unable to find API: cifs-session-list-iter-start

[CHAPLIC123]

I've been using the powershell commandlets against netapps filers to great effect; however one machine it doesn't work. I can connect happilly but if I run a command I get the above error, in detail below.

Any idea what it could be? I have permissions and every other filer I have it runs fine. Version on ontap issue?

Yes, your Data ONTAP version is the issue.  The API in question was present in 7.2, but it wasn't supported by vfilers until 7.3.
