Can an lpp_source and SPOT created from AIX media be used to install the VIO server?
No. The AIX media and the VIOS media are not interchangeable. All of the device drivers and the other software needed to install the VIO server are located on the VIOS media. The AIX media does not contain all of the same device drivers or software necessary to install the VIO server, so AIX resources cannot be used to install a VIO server.
