[comp.sys.hp] Would you believe...

jsadler@bcstec.UUCP (Jim Sadler) (09/06/89)

I recently ran into a problem.  When we wanted to use NFS to make usenet 
available to some of the local machines, I found out that HP version of NFS
will only export whole file systems only and not sub-directories.  Not wanting
to publish the root partition we decided to re-partition the /users drive.
(By the way this is a 825CHX running HP-UX 3.1 with a 7963B that has all 3 
305 Megbyte drives in it.)  The /users drive is a single drive of 305 Meg.
2 partitions of 150 Meg each sounded good.
So after 2 days of reading manuals to make sure things were done correctly,
backing up the users files, etc.  First we looked in the /etc/ disktab file
and found the following:

# @(#) $Revision: 62.2.1.1 $
hp7959|hp7959B|hp7963|hp7963B|hp9263B:\

	:s15#16384:

If you will notice the closest you can come to 150 Meg partition is s5 at 
197Mb and then you might be able to combine 3 or 4 other sections for the 
remaining 108 meg.
No problem we think we will just change the disktab table to include 2
partitions of the size that we need.

We went to it and ended up with a "Write error at block xxxxx"
Scratch our heads for a couple of more days to make sure we didn't miss 
anything, give up and call the HP response center.  The first answer I was 
given I didn't believe, after verifing the the answer I had to scrape my chin 
off of the floor.  HP hardcoded the disktab table into the kernal !!!!!!

FLAMES

HOW could you believe that the selection of partitions sizes that you chose
would fit what yours customers need !?  First you have a lousy choices of 
sizes, either very big or very small.  Then the manuals read that you change 
the disktab entry to have different size partitions, but then that doesn't 
work because you put the "allowable" sizes in the kernal.  I really don't 
believe it!!  I can't figure out if it was stupidity or lots of gall.  

You know I keep telling my co-workers that HP builds nice machines, after
they hear about these types of gaffes they just say "sure jim" and snicker.

FLAME OFF

Other than hacking the kernal anyone have any ideas ?
 
 By the way the response center said that they would submit an "enhancement 
 request".  Jim's translation "HP might fix this in the next decade".

I notice two parts to your complaint about disk sections -- that they are
not configurable, and that a manual says they are.  Please note, I'm NOT
arguing with you about the value of hard-coded disk sections, but I'd like
to know of any reference where an HP manual says to change an /etc/disktab
entry.

While it is true that you must export an entire file system, it 
is possible to mount sub-directories. It is also possible to 
specify read-only as needed.

For example, I have X11 NFS-mounted as four parts out of the
"/usr" file system which is exported from the host machine. 

Good Luck,

Pity the poor jerks like us with 9000/3xx machines that do not, and will
not, have disk partitions at all.

Do you think if we went on and on and on at HP about their 
stupid disk philosophy and their pathetic 1/4" tape cartridge
philosophy, do you think that they would eventually do something
about it. 

I'm the first to look at an idea that may not be 'standard' but
is 'better'. An idea that is 'non-standard' and 'worse', you can invent
your own fate for. 

Please HP, WAKE UP TO THESE COMPLAINTS.

This issues are.

1). I shouldn't have to export my root file system whenever I export
    any directory. I suppose this is my fault for buying large hp discs
    at outrageous prices :-)

2). I don't like the idea that any bozo user can fill up my entire
    file system by writing garbage in an otherwise innocuous directory.

comp.sys.hp is not an HP sponsored news group;
far from it: any response you see here from
HP personel is an unofficial response.  the
bottom line is that you can't expect a single
thing from this news group.  (fortunately,
though, HP employees respond with advice just
like any other net reader can.)

if you have a problem, you should contact your
HP representative.  i believe they are called
"field engineers."  that is the official channel.
you CAN expect response from your FE; you should
even DEMAND response if you have problems.

Not wanting you to think that your concerns are falling on deaf ears:
HP is aware of your needs and has been for some time.  We are currently
looking at solutions to the issues you bring up here, but I'm not in a
position to promise you anything at this point.  Neither is this a hint
that anything is in the works.

I can tell you that complaining to HP *DOES* help your cause.  This
discussion group gets pretty wide readership in the lab at HP, though we
are reserved about responding because we really can't make commitments
to customers.

If you want to give input and get commitments about specific features,
your best bet is to dog your HP sales rep.  She will be able to speak
the magic language of "XYZ feature is worth this many $M in sales
revenue" to our marketing folks in division headquarters.  This in turn
results in an "Add XYZ to HP-UX in the N.M release" order to the lab.
We in the lab love it when the customer base gives this kind of input,
because it usually aligns well with our own needs internally!

I hope this insight gives you some idea of how your input can influence
HP's products.

For those on software support, you can send an SPR over the HP

re: "Do you think if we went on and on and on at HP about their stupid disk
     philosophy and their pathetic 1/4" tape cartridge philosophy, do you
     think that they would eventually do something about it."

Quite possibly.

HP's "pathetic 1/4" tape cartridge philosophy" consisted of getting into the
cartridge tape game about 5 years before QIC, back when there were no
obvious standards other than the one HP chose, the 3M "HCD" format.  HCD has
some unique advantages (random access, update-in-place, ECC) that are too
widely used to abandon.

HCD and QIC are different enough that no one has ever built a drive that
handles both, nor do I think it possible to build one economically.  HCD
and QIC drives can also mis-rewind (or even unspool) each other's tapes.
QIC drives can destroy HCD factory pre-formatting.  Until the Apollo
acquistion, HP tried to keep as much distance as possible between HP and
QIC, lest HP customer risk media accidents.

However, "Standard is better than better" and "the customers have all the
votes".  It is likely that for at least write/read, HP will support both a
built-in and external SCSI QIC drive in a future release (they can be made
to work today).  There is also some chance of supporting boot from QIC.

Paul Breslaw responds to a note from Jim Sadler (Hi Jim!) with:

I think it's worth pointing out that, for example, Hewlett-Packard
was very involved with the initial development of the R-DAT data
storage mechanism, especially as related to computer usage, as well
as with WORM and other optical media too.

It would not be surprising to find that HP is poised and ready to
ship many interesting and exciting new media for their computers,
including CD-ROM, for the 9000 series (300 and 800), DAT backup 
units (that, I believe, have been floating around Bristol Peripherals
Division in England for at least a year now), WORM systems, and 
so on.  Further, with the current migration from slow HP-IB to the
much faster SCSI interface, I also expect that HP will allow you
much more freedom to configure your disk/etc in any way you'd like.
Further, you'll be able to buy ANY SCSI disk and plug it in (I hope!!)

[besides, you can get most of these, including WORM units and 8mm
 backup systems, from third parties TODAY]

As far as 800 disk partitioning, I too would have to place my vote
with Jim that hard coded partitioning tables is a pretty poor solution
to the problem -- I mean, even MS-DOS has a better solution than that!
The whole idea of partitioning is to allow the end user site MORE
ability to slice their disk up into 'virtual disks' with hard byte
limits after all...

300 disk partitioning is something that I can see would also be of
possible value, but I am not aware that there are any plans afoot
within the company to work on that particular problem.  (err, 
enhancement request)

Now, for my own two cents worth, what I would like to see is for
HP to offer a 'binary compatability mode' feature similar to the 
one that allows MPE-V programs to be run under MPE-XL.  In the
9000 universe it would mean that I could take a binary that was
generated on a 300 machine, say, and run it in "300 compatability
mode" on the 800 machine.  It would probably have a 5-10% performance
hit, but that's cool.  Think of the massively improved migration
path (especially when the 800 is so much more expensive!).  Of
course, 800 compatability on the 300 series would be required too.

Anyone else think that'd be a useful feature?  (we've not even 
started talking about a PORT/BSD type application either, which
would aid in the porting of sofware from a 4.3 BSD environment
into the HP-UX environment, partially due to the muddying of the
waters that OSF/1 is going to have...!)

Here's one I yap at my sales rep all the time:  I have found from
talking to our local AI group and people at the University of Maryland
that the inability to put local user files on a "discless" node leads
to the reaction "Oh.  What a shame, SUN can do it" right before they
walk away.  Any leads on when HP "discless" nodes may become a cluster
with user disks and printers on every node?

While on the subject of discless nodes, who was the genious who restricted
the 834 to 2 users?  I don't know about you all, but if the 834 comes up
as a discless node it inherits the licenses from the parent.  Doesn't this
bypass the 2 user restriction?  Just curious, I'd NEVER do this you see :-)

We've been using 600 MB WREN-V's on HPUX series 300 machines w/ the
SCSI adapter for about 4 months now; a very nice combination.  We did
have some trouble initially with the unusual connector[1] HP uses on
its SCSI board, but once that was overcome everything's spun along
just fine.  I haven't tried any other 3rd party stuff yet.
-----
[1] Just unusual for our environment.  HP uses a centronics-style
cable, & in our Sun-oriented environment we were used to Sun's DB-50
style SCSI connectors. [I hope you can figure out what I mean, that's
not the correct terminology for these connectors.]  But I think both
connector styles are kosher for the SCSI bus.  Compatible centronics
connectors were a bother to find, however.

Doesn't / didn't Apollo have some feature like that, you could
manufacture a mixed-architecture executable?  I don't think this
is based on emulation, but rather had different instruction set-
based executables rolled up together.

I wonder if you could get as little as 5-10% performance hit 
from an emulator.  (5-10% less than what?  Probably not a 370!)
Is the "Precision Architecture" really fast enuf to do this?

Incredibly unlikely.  This would require an entire virtual machine to be
written to emulate the 68K on the HP-PA, which was not designed with this
purpose in mind (it was designed with the 3000 in mind, hence the easier
migration path on the MPE side).

Such an effort would be almost guaranteed to have significantly greater than
a 5-10% performance hit, and in any case, would be a gigantic design and
development effort (unlike disk partitioning, would seems to me to be just
a relatively quick hack).

Not at the HP-UX 7.0 Release, which was just announced.  Sorry.  Local
disks and printers are supported in raw (vs. character) mode, though.

I don't believe that this is the case.  The "uname" structure is
initialized at boot time, and even if the 834 is running as a diskless
node, it will have its own kernel, which will correctly identify the
hardware as an 834, thus filling in the uname structure correctly.  This
will preserve the 2-user restriction.  Also, please note that the 2-user
restriction applies to logins via login(1), rlogin(1), and telnet(1)
only.  Access via remsh(1) is unrestricted.

Marc Sabatella (marc@hpfcso.HP.COM) responds to my note about the 
possibility of a 300 binary emulation mode for the 800 and vice 
versa with the following comment:

While I don't for a minute believe it would be easy to accomplish
what I'm talking about, the fact is that HP has a fragmented 
hardware line with two very different architectures, and the reality 
that many customers in the field are extremely anxious about this
and its effect on migration paths, etc.  

As Don Souza, a highly placed DEC marketing manager, has indicated in
an interview a few months ago, DEC recognizes this as a weakness of 
HP; he showed me slides that demonstrate that their particular product
line (DEC) has a much better hardware growth path, for example.

The significance isn't that DEC is right or not, but rather that
they think it's an important enough issue to put quite a bit of time
and money into pushing with industry analysts/journalists.  Why?
Because, bluntly, customers don't want to have obsoleted hardware
and don't want to buy new computers every year or two.  Further,
they want to be able to gracefully upgrade -- the 950 -> 955 -> 960
upgrade is EXACTLY THE RIGHT SOLUTION to the problem, from a 
customers point of view; everything is the same, you get a trade in
value on the old CPU board, and lo! things are just lots faster.

When we look at the fragmentation within the HP/Apollo market, however,
we can see a rather shocking jumble, with machines all the way from 
the now HP-endorsed "SCO Xenix" on Vectras to the 300/800 schism to
the dual Apollo lines too.  FIVE DIFFERENT UNIX PLATFORMS!  That's a
lot of confusion for the customer, isn't it?

Or look at the problems of dealing with RAM cards when migrating up
in the 9000/300 line itself.  There are at least three different
types of cards required, each incompatible.  Not a good way to 
protect MY investment in hardware...

The point I'm trying to make is that I don't see it really as a question
of whether it's a hard implementation or not, but rather a point of
possible differentation in the marketplace; lots of vendors currently
are confusing their customers with RISC and CISC hardware lines, and
HP could be first under the wire with complete binary migration 
capabilities across the line...

Remember; if Unix is to continue to be successful, it's going to have
to move from being an engineer's operating system to being a commercial
viable product environment, and that means that difficulties in the
implementation of desired features (like a fast and compact COBOL for
the 9000 series that accepts MPE-V and MPE-XL programs untouched) will
become more and more irrelevant.  If HP doesn't do it, someone else 
will, and that'll just be another mark against the 9000 series and
another hit against them in competitive sales situations...

Besides, if it's true that the HP-Precision Architecture line wasn't
designed for 68K compatability, well, add that functionality in the
new PA-PLUS that is being designed as we speak at IAG and with the
help of the new Japanese partners...

Solutions, not excuses.

Or isn't there "a better way" ?

One other quickie:

> ... unlike disk partitioning, would seems to me to be just a 
> relatively quick hack.

Yup, and maybe that's why customers in this group and elsewhere are 
complaining that it isn't a very good partitioning scheme and that 
it, again, isn't available across the entire HP 9000 series?  Hacks 
are the last thing that a commercial customer is going to be 
interested in.  And with HP, at least in the "good old days", hacks 
were the last thing that you'd expect...

Oh, thanks!  I can't even get my sales rep to call me back with prices
on shipping products I know I want to buy!  OF course, the other problem
is that she doesn't know anything about the products.

Sheesh,

You are missing the point.  I don't want to rely on the person doing
the mounting (the nfs client machine) to decide which directory from
my machine (the nfs host) he wishes to mount.  I want the control to
determine what the client has access to.

While it is indeed possible to mount directories read-only, it
is NOT possible to export read only. This is almost pointless.
