Hello Raymond,
Physically, yes it would but (I keep asking to ensure that I get
the question right),
Would the below generate one Control Block in VM that would
become a bottle neck,
Where if you have 4 control units defined, would the system know
that one is being used
And then use the other to pass the I/O (commands and the like)?
I am sure that this may not be problem until we hit something
like 3000 i/o (per the manuals)
But it would seem that having a control block busy (enqueued for any
reason) would case other code to
Be activated.
Some DASD manufactures will tell you that placement of files do
not matter, it does
still matter if you want the best response time you can get.
We are pushing the 6 ESCON channels at 5-10% most of the time,
but I have seen them jump to 30%.
I intend to keep the FICON channels at under 5%.

Kevin, Edward,
Would not -
CU0130 CNTLUNIT CUNUMBR=0130,PATH=(30,31,40,41),CUADD=01,
X
UNITADD=((00,256)),UNIT=2105
DV800 IODEVICE ADDRESS=(0800,256),CUNUMBR=(0130),
X
UNIT=3390
give you the same results??

Thanks that is what I was looking for.
I have this right now.

You definitely want and should take advantage of all four channels.
Your CHPIDs look okay to me, but consider something like the following
for your CNTLUNITs and IODEVICEs
CU130 CNTLUNIT CUNUMBR=130,PATH=(30), X
UNITADD=((00,256)),CUADD=0,UNIT=2105
CU140 CNTLUNIT CUNUMBR=140,PATH=(40), X
UNITADD=((00,256)),CUADD=0,UNIT=2105
CU131 CNTLUNIT CUNUMBR=131,PATH=(31), X
UNITADD=((00,256)),CUADD=0,UNIT=2105
CU141 CNTLUNIT CUNUMBR=141,PATH=(41), X
UNITADD=((00,256)),CUADD=0,UNIT=2105
CUA30 CNTLUNIT CUNUMBR=130,PATH=(30), X
UNITADD=((00,256)),CUADD=1,UNIT=2105
CUA40 CNTLUNIT CUNUMBR=140,PATH=(40), X
UNITADD=((00,256)),CUADD=1,UNIT=2105
CUA31 CNTLUNIT CUNUMBR=131,PATH=(31), X
UNITADD=((00,256)),CUADD=1,UNIT=2105
CUA41 CNTLUNIT CUNUMBR=141,PATH=(41), X
UNITADD=((00,256)),CUADD=1,UNIT=2105
DV800 IODEVICE ADDRESS=(0800,256),CUNUMBR=(130,140,131,141), X
UNIT=3390,UNITADD=00
DV900 IODEVICE ADDRESS=(0900,256),CUNUMBR=(A30,A40,A31,A41), X
UNIT=3390,UNITADD=00

Subject: REquest for IOCP for DS6800 FICON Z890
Hello Everyone,
I am just getting the IOCP ready for a ds6800 connected to four
ports on the Z890.
I would like to some help with the IOCP.
Even though we have to have LPAR, there is only one called
PROD.
The FICON cards are the 2320 FICON Express SX. Two 1 gig ports
per card.
I would like to have all four ports able to access all dasd.
I am figuring to have the DS6800 formated for 30 3390 mod 3, 306 3390
mod 9, and 30 3390 mod 27. (366 devices)
I know that am missing some RESOURCE PARTITION and various CSS
commands.
I am reading about them now. And I still have lots of
questions.
I would appreciate any insight and idea's. Than
CHPID PCHID=130,PATH=30,TYPE=FC,SHARED .FICON DS6800
