In case anybody cares but doesn't know, the authoritative reference on this subject is the following IBM publication: IBM 3880 Storage Control Models 1, 2, 3, and 4 Reference Manual (Publication Number GA26-1661) I happen to have a (hard) copy of this manual, the -6 version dated April, 1983. IBM didn't publish soft-copy documentation back then, only hard copy. Nevertheless, I was able to find a soft-copy version on the internet. Someone took his hard-copy version, ran it page-by-page through a scanner, and converted the results to a PDF file. This copy is a newer revision, the -9 version, dated September, 1987. See http://www.bitsavers.org/pdf/ibm/dasd look for the link titled GA26-1661-9_3880_StorageCtrlDescr_Sep87.pdf single right click on it and select "Save Target as" from the pop-up menu to download it. Open it with whatever you normally use to open a PDF file. Of course, you can't search it for text, since the whole manual is a collection of images, due to the way it was created. You won't get very far into the document before you will find a list of devices supported by the control unit. A 3390 is not one of them. But a 3380 is. The only other device supported by the Linux kernel that the 3880 Storage Control unit supports is a 3370, which is an FBA device. It is (correctly) listed in the device table in drivers/s390/block/dasd_fba.c. -- .''`.
