Re: Synchronizing the IOCDS and the DS6800

IIRC, the relationship is implicit. The first ADDRESS refers to the first logical volume, the second ADDRESS is the second logical volume, and so on.

This can get tricky if you delete a logical volume.

HTH and good luck

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.

Thank you
