Which sort-of was the answer. I made a mistake with Google. I should
have put the message in quotes. When I did that, I found three binaries
at the MIT (newfs, mkfs, mount_nfs) and one Japanese PDF for a Compaq
RAID. I was able to find an English PDF on

This says that for Solaris 2.5(.1) and 2.6, 64 heads is the maximum.
This seems to be unchanged for Solaris 7 and 8.

Fortunately, this RAID controller allows me to limit the number
of cylinders, heads, and sectors. This is what I found to work:
  <IFT-ER2000-0323 cyl 65533 alt 2 hd 64 sec 506>

A greater number of heads gives a different error message,
which I didn't save, sorry. Funnily, when you limit the geometry
down to something that cannot accomodate the capacity of the LUN,
format will correct this for you :-)

You can also specify the number of heads for newfs, once you
know this helps ;-)

           -t ntrack
                 The number of tracks per cylinder on  the  disk.
                 The default is taken from the disk label.

I preferred changing the array.

Summary^2: Nice RAID controller, shitty error handling in mkfs_ufs.

HTH other people,
