HP-UX model command

[Simon Waters_2]

Silly question to ask after years doing HP-UX Admin.

Is there a document that explains the logic behind the output of the model
command?

I've heard a few cynical comments from HP people over the years about product
naming, but no matter how tortured the logic I'm sure there is some, or at
least a look up table.

It use to be 9000/715/50, meaning a 9000 series, 715 workstations at 50Hz, and
you can look up in sched.model the appropriate PA-RISC details.

But the 9000/898/K370 seems to work a different way.

It is just I spend too long checking out dmesg, sam, and the like, when HP
support can say - oh a K Series with three 8200 processors...

Sadly the "logic" disappeared once we started running out of the 800 numbers.
Way back in 1986, when the first box rolled out, it was the 9000/840.
This progressed to the next systm, the 9000/825, then upgrades made it the 835
and 845. Around this time, along came the 850/855/860/865/870 and the
progression continued until about 5 years ago, when the numbers ran out while
the Nova series were current (8x7 systems, which became F,G,H,I systems).
The decision was then to go for the Alpha characters, and build on those, so
unfortunately there is no REAL logic anymore.
Old-timers like myself can quote this verbatim, but with ever newer systems
rolling out, it gets harder every year.
The one thing I can suggest is to look at /usr/lib/sched.modles on a 10.20
system, else on 11.x look at /usr/sam/lib/mo/sched.models

Another good place to look for models on 11.0 is the /etc/.supported_bits
file.
