"Screenshots in EMC and Windows GUIs"

Server 2012 R2 cluster. Storage for cluster is EMC VNXe 3200 (SMB3 shares, not ISCSI). Veeam used for backups.

There are VSS snapshots on the EMC that were created by Veeam, using the 'VNX2e VSS Provider'.

There are five of these snapshots, going back several months.

I've opened a case with Veeam and EMC. Neither have come up with an answer.

Daily backups continue to work, creating snapshots, using them, then destroying them as expected. When the backups run, the snapshots are exposed to "vssadmin" or "diskshadow" commands on the Hyper-V hosts.

These orphaned snapshots do not show in "vssadmin" or "diskshadow".

I'm hoping there is a command that can be run from the HyperV host that can access and delete the orphaned snaphots (shadows).

Here are commands run on one of the HyperV hosts. Results are similar on the other host.

C:\vssadmin list shadows
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool

    NOTE: The attached pic of screenshots shows one valid snapshot (recent date). That snapshot was created by Veeam during a back. That snapshot was deleted automatically when the backup completed. The other snapshots are what I need to delete.

    EMC Support has resolved this. It took a couple of weeks of them working on it, along with Veeam support working on it. In the end, EMC Support had to connect as "root" and run commands. I am including some of the (sanitized) commands below. There isn't a case where I would run these without EMC support, but I want to add the notes to this question, as someone might find this and bypass weeks of collecting logs for vendors.

This is resolved. See my comments above for the answer.

It did require an EMC support call, and even then took many sessions with the tech. Once he had the correct direction/commands, the problem was resolved using the commands below (with a different "oid" for each snapshot that needed to be manually deleted).

MluCli.exe destroysnap -srvc_cmd -oid 0x9000007e7 -system -fast
