Type Max IQD chpids Max CUs/chpid Max Devs Max Interfaces z800/z900 4 16 3072 1024 z890/z990 16 64 12K 4096 If you need more that 256 devices on a chpid, you have to define additional CUs in IOCP. Every address shared across 'n' LPARs counts as 'n' devices against the maximum device limit. Device the device count by 3 to get the maximum number of stacks or interfaces. The IOCP User's Guide for your machine has these numbers (except Max interfaces) documented in the Machine Limits appendix.
