In some cases, restore of a database via VESQL may fail with the following error message:
This issue may occur if the VM disk on which the SQL database files are located is attached to a SCSI controller with pciSlotNumber larger than 1024.
pciSlotNumber of a SCSI controller can be found in the .vmx file of the VM.
Note: This issue is corrected in version 184.108.40.2068+ as part of Update 2 https://www.veeam.com/kb2024
To resolve the issue, move the disk to a SCSI controller with a smaller pciSlotNumber and re-run the backup.
