Event ID 157 - disks do not exist RRS feed

  • Question

  • I've seen a lot of posts reporting Event 157, most seem to be related to when backups are running.

    My experience is a little different, I have 2 CAS servers, both virtual, both running Server 2012 R2. Both servers report Disk 2 and Disk 3 were surprise removed at the same time every day (around the time snapshots are taken). However, neither server has, or ever had, disk 2 or disk 3. Seeing it report these being removed was a surprise to me for sure!

    Both machines are virtual (VMWare), backups and snapshots are SnapDrive

    Anyone have any idea what is casing this and how I stop it? My boss has spotted it and wants it fixed even though it is not actually causing any issues.
