Here are the parameters that we used to format our CDC Wren VII. Those
info come from the format.dat file of SunOS 4.1 beta:

disk_type = "CDC Wren VII 94601-12G" \
	: ctlr = MD21 : fmt_time = 4 \
	: cache = 0x11 : trks_zone = 15 : asect = 5 : atrks = 30 \
	: ncyl = 1703 : acyl = 2 : pcyl = 1931 : nhead = 15 : nsect = 80 \
	: rpm = 3600 : bpt = 31410

we got some timeout problems when we tried to format the drive at first.
We dis installed some patches coming from SUN to support the hexabyte on
the SS-1. Those patches are named CONSULT. You can ask your SUN rep about
it.  (It appears that those patches are correcting other problems
associated with the MD21 controller.)
