That's right, M23*7*2, not M23*8*2 (Swallow 5).

I am given to understand that these beasts are running fine on
somebody's Symmetry somewhere (Sequent doesn't support them).
Unfortunately, the helpful, nice people who gave me to understand this
were *not* the people whose bid was lowest (praise be to University
Purchasing, who saved us money and cost us decent support).  When you
don't buy from people they tend to be less helpful and nice, so now we
have two M2372 disks but no formatting info.  [ No flames, please,
that's not the whole story. ]

As far as the /etc/disktab entry goes, I can figure out everything
except "ns".  Following the wonderful instructions in the Fujitsu
manual I get ns#80.  That's fine with me, but the Swallow 5 entry is
ns#81, and

	ns * nt * nc+3 * 512 = 81 * 27 * 748 * 512 = 838MB

which is not the size of a Swallow 5.  So the Sequent folks did
something funny -- they aren't using all of the disk.  On the other
had, the M2351 entry is what you would expect, so now I don't know
what to believe.

Anyone out there have a working disktab entry (plus any random driver
hacks, if any) for a M2372 on a ZD controller?
