Rusty,
I am attaching the Debug code I used for the RAW_DISK stuff
would you run it.

Well, this is an Ultra 5 running Solaris 2.5.1.
I modified orcallator.se to tell me what the short names were as it added
them,
and it got this list:
adding raw disk. short name: dad0
adding raw disk. short name: atapicd2
adding raw disk. short name: fd0
(this is on SunOS msfree 5.5.1 Generic_103640-32 sun4u sparc
SUNW,Ultra-5_10)
Over in the other building I found one machine that gave me this:
adding raw disk. short name: sd0
adding raw disk. short name: sd1
adding raw disk. short name: sd2
(and that was on SunOS cass 5.5.1 Generic_103640-24 sun4u sparc
SUNW,Ultra-1)

Well, like I say, I did this (more comments follow the code stuff):

I've got Version 1.28b4: Mar 27, 2001, with the above patches at this point.
The trick was here:
if (short_name[0] != 'm' &&
short_name[0] != 'n' &&
+ short_name[0] != 'f' && // fd fails on my sun ultra5 - rcarruth
+ short_name[1] != 'd' && // ditto - rcarruth
And it seems to work fine on all the machines I've tried it on (27 machines)
So, like everyone is saying - now what? ;-)
