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.
