Good question Billy, I'm waiting to see what the responses are ! In my environment, the SAD screen will show all 4 FICON channels to the DASD with activity. What I don't know is it VM balancing the load or the SAP engine doing the I/O. Inquiring minds want to know ! LOL Bubba
... snip If VM is doing I/O to one DASD volume only, say a DDR DUMP or RESTORE, and everything else is equal, will VM use multiple channels to get to the one volume, or will it do all it's I/O on whatever channel it gets first and only that one channel? Thanks, Billy
