The maximum realizable 3390 mod number with an EAV is 241,182. You had best allow for six digits. This number is the result of dividing 16 to the 7th power (the maximum possible number of cylinders) by 1,113 (the number of cylinders in a 3390-1).
The DCE, which is findable from one of the may UCB segments and/or UCBxxxx system services, contains the number of cylinders. This number is also in the data returned with the Read Device Characteristics CCW. The DCE can also be dumped with the DEVSERV QDASD operator command.
