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:
