Physical I/O Device (physio_device) Resource

A physio_device resource is always contained within a <Content> section. This resource can be modified by using the add-io, set-io, remove-io, create-vf, destroy-vf, and set-domain subcommands.

The following examples show how to perform actions on virtual functions, physical functions, and root complexes.

• The following XML example fragment shows how to use the ldm add-io command to add the /SYS/MB/NET0/IOVNET.PF0.VF0 virtual function to the ldg1 domain.

• The following XML example fragment shows how to use the ldm create-vf command to create the number of virtual functions specified by the iov_pf_repeat_count_str value (3) with the /SYS/MB/NET0/IOVNET.PF1 physical function. You cannot specify other property values when you create multiple virtual functions with the iov_pf_repeat_count_str property.
