Thanks for the information all. The intent of the folks that were designing this was to keep the 3 zone environment segregated. However as I learn more about this I tend to agree that we could get away with one switch in the case where multiple switches are using the same OSA using different OSA address triplets.

That is, LPAR1 and LPAR2 can share an OSA chpid. The device numbers used by each LPAR are not important - they can be the same or different - it depends on the IOCDS. Within a single z/VM LPAR, the same device address cannot be used, but as with LPARs, you can have multiple VSWITCHes share the OSA using different device addresses. But when that happens, I start to question why you need two VSWITCHes. Alan Altmark z/VM Development IBM Endicott
