Abstract

Drivers in different functional paths can use different types of identifiers for the same hardware device, such that the drivers may not be able to natively coordinate their actions related to the hardware device due to incompatible identifier types. However, a driver at a file system layer of one functional path can obtain a volume Physical Device Object (PDO) identifier at a volume layer and find a disk PDO identifier at a disk layer that is associated with the same device number. The driver can also find a parent device instance identifier from the disk PDO identifier, and use the parent device instance identifier as a plug-and-play (PnP) identifier for the hardware device during communications with a second driver in a PnP functional path.
