After the root disk is configured for DMP control, the device is visible as the root volume group (rootvg) to the operating system. DMP controls the paths to the device. For certain maintenance tasks, the operating system needs to access the underlying paths. DMP provides a method to release the paths to the OS during those operations, and resume control of the paths after the operations complete.
The following sections give the procedures for common administrative tasks.
