It means that one of the snapshots in that collection was deleted.  Most likely because you didn't have enough snapshot reserve allocated to that volume.  If you look in the events you should see a message telling you that it was deleted.   Regards,  -don
Good morning, I was wondering if someone can please help me resolve an error I receive.  When I create a Volume Collection for snapshots, every so often some of them are in red font.  Why is it that at one point, say yesterday, it was fine (black font), but today it's in red font?  The error say something along the lines of "missing one snapshot".  If a snapshot was successfully created, shouldn't it be okay for the existence of that particular snapshot?   Thank you!
