Need some help with a WFA workflow that creates a CIFS volume with snapmirror XDP replication.

[bruce_breidall]

running WFA 4.0, and looking at the release notes of 4.1, it appears it is not possibe to create a type XDP i.e. snapmirror extended_data_protection. I have managed to create a copy of the existing snapmirror command and am able to generate the type XDP. However, it fails on the invoke-expression of the modified powershell command. The errors shown below (note that I logged the contents of the $expression). Can anyone put me on what I have missed in creating the modified snapmirror command to include the extended_data_protection type? Be forewarned, I am not a powershell expert, but I think this has something to do with how Invoke-Expression is passinig parameters to the netapp powershell cmdlets. I also installed the latest (4.4) PSTK, running PS 4.. Thanks in advance.

Bruce,

I am running WFA 4.2.0.0.1, 18 Feb2018 and it does not support snapmirror -type xdp either.  The Dictionary Entry for "Snapmirror Type" is of type 'Enum' in the cm_storage schema.  The Enum values need to be update to include "extended_data_protection".  There also needs to be a few lines of Power Shell added to the "Create Snapmirror" WFA Command.  I'm hoping Netapp will provide this in a Patch update for WFA 4.2.

The issue is how netapp has confused the terminology through their evolution of software releases.

XDP (Extended data protection) is the same as vault, so try specifying "vault" as the snapmirror type...

in my WFA version which is same as yours vault is not an option. any ideas?
