Hello. 1) You are using KAIO feature (Kernel Aio), that means yours kio virtual processor doesn´t have a VP number. It´s totally normal in kio output (note that it is just showing your statistics, it´s not a real VP class). Eg: do an onstat -g glo command, and you will see there´s no kio vp class present there). 2) the link below: http://publib.boulder.ibm.com/infocenter/idshelp/v115/topic/com.ibm.admin.doc/id s_admin_1286.htm?resultof=%22%66%69%66%6f%22%20%22%66%69%66%22%20%22%76%70%22%20 will provide you more information about fifo vpclass.
