Ted, 3380-3 is HDS terminology for a standard size 3380 when you format the Parity Group. It the value elected on the drop down box and creates 3339 cyl volumes unless you choose to carve it up into custom sizes.
I've seen 3390-3 used by customers to describe the same emulation on EMC. However, it may be that they were using the HDS term when communicating with us. I've seen it frequently enough to feel that it is a common term across those customers that still use 3380 format. If your experience is limited to IBM TCM, or it has been a long time since you used 3380 format volumes than I agree you may not have come across this expression.
