Domain Configurations Command Functional Outline
1.2 SPARC M12/M10 ldm create-vf Creates a virtual function (VF).
Hardware Resources
ldm destroy-vf Destroys a virtual function (VF).
1.3 What is a Physical
Partition? Note that I/O devices can be reconfigured dynamically depending on the version of Oracle VM Server for SPARC. For details, see
1.4 What is a Logical Table 1-2, the Product Notes of the server used, the Oracle VM Server for SPARC Release Notes of the version used, and the
Domain? Oracle VM Server for SPARC Administration Guide.
1.5 What is Physical
