Barry, I don't know if this will help or not. The DS6800 installation, troubleshooting and recovery guide goes through building out the storage on the array. Unfortunately it leaves a "bit" to be desired on how to tie this to z-boxes. GC26-7678 (I have -08 generation) is the manual and chapter 7 is where I found the info 4 years ago when I put ours in.
When you define the LCUs on the 6800 you need to give them LCU IDs as well as SSIDs. I BELIEVE the LCU ID corresponds to the CUADD field in the IOCDS CU definitions. As far as defining the actual addresses on the 6800 to addresses in your IOCDS, when you define the volumes on the 6800, you tell it which LCU you want the volumes put into, then when you either give it the base address and range (or allow it to default to the lowest number available) you are in essence giving it the address the Z will see. For example, on my 6800, I have LCUs 0-3. I have disk defined on each of the LCUs that have range 00-1E on LCU 0, 00-0D each on LCUs 1-3. On my Z, I have the 6800 defined as 4 CUs 1000, 1100, 1200, 1300. These correspond to CUADD 0-3. The Z has all 256 device addresses defined on each of the 4 CUs. I actually only have available on the Z, addresses 1000-101E, 1100-110D, 1200-120D, 1300-130D. Device 130D is 6800 address 0D on LCU 3. To use the addresses the customs driver offering gives, you would need to (in the IOCDS) define CU D00 on the CHPIDs plugged into the 6800 and make sure you have device addresses 40-5F defined on this CU; then, on the 6800, define addresses 40-5F on the correct LCU. HTH. Rex -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Schwarz, Barry A Sent: Tuesday, July 27, 2010 10:05 AM To: IBM-MAIN@bama.ua.edu Subject: Synchronizing the IOCDS and the DS6800 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.
