Am I missing something? Is there a better way >to configure this? You are ATTACHing/DEDICATEing one address to your guest. You can have multiple address on one Ficon chpid. Eg in my system: CHPID PCHID=151,TYPE=FCP,PATH=(CSS(0),35),SHARED, * PARTITION=(CSS(0),(BWVML),(=)) CNTLUNIT CUNUMBR=3500,PATH=(CSS(0),35),UNIT=FCP IODEVICE ADDRESS=(4000,032),CUNUMBR=(3500),UNIT=FCP, * PARTITION=(CSS(0),BWVML) Which means that I have addresses 4000-401F to attach to guests. In theory that could mean 32 different guests, but you have to consider aggregate bandwidth as well. Hope this helps.
