We are installing a new z10 with a minimal DS6800 in a very small data center (to replace our venerable MP2003). Using the SMC, we have configured the DS6800 with RAID 5 to give us 250GB of usable storage set up as eleven 3390-3s and the rest as 3390-9s. (We wanted to use RAID 10 but the system insisted on keeping two of the DDMs in reserve so we ended up with only 125GB which is not sufficient.)
I am using the Stand Alone IOCP on the z10 HMC to build the IOCDS. I have looked at every DS6800, HMC, IOCP, and HCD manual I could find but I cannot find any description of how the ADDRESS operand on the IODEVICE statement relates to the logical volumes on the DS6800. I have the same problem relating the CUNUMBER and CUADD operands on the CTLUNIT statement to the physical and logical control units on the DS6800. The Customs Offering Driver manual (GI11-2843-04) shows 3390 devices at addresses D40-D5F. Obviously I'm missing something but I see no method of assigning those addresses on the DS6800. A pointer to the relevant section of a manual would be greatly appreciated. Suggestions on how to use RAID 10 would also be welcome.
