Oracle Database Error ACFS-03918: Volume Snapshot Device Exists
Description
This Oracle ACFS error indicates that an attempt to create a volume snapshot failed because a device with the intended snapshot's name already exists in the system. This typically occurs when a previous operation left a residual device entry or a naming conflict arises.
Error Message

Known Causes
3 known causesResidual Device Entry
A previous snapshot creation or deletion operation might have failed or been interrupted, leaving behind a device entry that was not properly cleaned up.
