I need to port a SCSI target driver from Solaris to HP-UX,
but I'm starting _completely_ from scratch as far as familiarity
with HP-UX internals and writing device drivers are concerned.
(On the other hand, how different can it be from Solaris and AIX?)

Is there documentation for this available from HP (like Sun's Solaris DDK
and "Writing Device Drivers" documentation), or a HP web site devoted to
device drivers similar to what Sun provides? Trying to search on
HP's web site gives me lots of pointers to Win95 device drivers for
their ink-jet printers, but little else.

Any clues/pointers would be much appreciated!

I am also writing a SCSI target device driver. There are two docs you
need, the DDG (Driver Development Guide) and the DDR (Device Driver
Reference). These can be downloaded via anonymous ftp from ftp.cup.hp.com
under the /dist/networking/drivers directory. The documentation is decent,
except that they leave out some important details and examples sometimes. I
am also trying to locate an example scsi device driver for HP/UX 10.20 so if
you run into one let me know. Please feel free to contact me direct via
email and maybe we can help each other out...

Oooohhh, having done that transition, all I can say is: it's like
stepping back in time to the mid-80's... LOL. DDI/DKI? We don't
need no stinkin' DDI/DKI... Real programmers do "nm" on the kernel to
find what functions they need...

The HPUX driver development guide (DDG) and Driver Development
Reference (DDR) are available via anonymous ftp from: ftp.cup.hp.com
under dist/networking/drivers.
