Virtual input/output for IBM Power Systems hosts

The system provides both single and dual Virtual input/output (VIO) server configurations on IBM Power Systems hosts that support VIO.

You can present the system volumes to the VIO server host bus adapters (HBAs) by using the same method as a standard AIX installation. For single VIO server configurations, volumes can be split up into logical volumes by the VIO server and mapped to the VIO clients. For dual VIO server configurations, volumes cannot be split into logical volumes, and must instead be mapped intact through both servers to the VIO clients.

The following website provides the most current information about multipath requirements and restrictions for the supported VIO configurations:
