Hey Adai,
You're right, It looks like it doesn't officially support it! Snapshot information is available in the UI, and the database view to return snapshots is there (but empty), but it would seem it wasn't officially supported in 6.0.
I've checked the 6.1 Beta and it looks like Volume Snapshot monitoring enhancements are listed in 6.1 to close this gap. I'm trying to get my hands on the beta at the moment to confirm this. We'll need WFA/OCUM and SnapProtect versions that all work with each other, so I may need to create a WFA powershell-based collector for other missing information anyway.
If you can help me get a hold of the beta so we can trial our options that would be greatly appreciated!
I'm also interested in if the CIFS ACL's are supported, which it appears they were in 7-mode but are not in OCUM 6.0 yet either.
Thanks,
- Michael.
