SMSQL Verification - Unable to Mount Database clone

Good morning,

We have a SQL 2014 database server, we run SMSQL 7.2.1. The SMSQL backup runs successfully however the verification, which runs on a dedicated verification server fails. Here is the error I am getting just for one of the database.

Please check with your storage admin if your snap autodelete is enabled on the volume hosting the DB or LUN.

If it is enabled check if there is enough space and in any case disable the feature as it is not supported with snapmanager because: who tells the snapdrive app that the snapshot was autodeleted if the host does not initiate the task?

Snapdrive would still think the Snapshot exists even if i twould be deleted.

Other possible issues could be virus checks for example.

Running the config wizard for a check is a good option too.

If the Config wizard shows any issues or warnings there might be a hint that helps in resolving this issue.
