Subject: HP 4mm DAT drive for RS/6000
Summary: To what extent do they work?
Date: 12 Nov 92 08:44:28 GMT
Organization: Mathematics Department, Monash University, Australia

I'm considering purchasing a HP 35470A 2.0Gb 4mm DAT drive to be used on 
an RS/6000 and I was wondering whether anyone with experience with this
combination could tell me:

  * Are there any problems/disadvantages with this combination?

  * Can a bootable image (mksysb) be created on these drives?

  * Is the actual performance as good as quoted?  (e.g. average 30 sec
    access for any part of the tape, 183 Kb/sec transfer rate.)

  * Was it recognised by smit and were there any problems setting it 
    up with AIX 3.2?  (Not that I'm there yet, but I hope to be soon
    by the good grace of IBM Oz!)  

Any advice would be much appreciated.  If you mail me then I'll 
summarise any responses if there's interest.

Thanks in advance

If it makes you feel better, their thin-wire connectors are a pain to get
at too :-{  However, you can {buy|make} a 6-inch AUI cable with a couple
15-pin D connectors and some ribbon cable, and this will work just fine.
No need for a "real thickwire" (i.e. AUI) cable.

	I haven't tried it yet m'self, but according to the manual...
	The system call chown's the symbolic link, but the "chown" command
itself chown's what the link points to.  Ergo, use perl.  :-)

  A remote /usr client has only ROOT parts of lpps/ptfs on it.  Since
root parts are very small, and a lot of the 3.2.2 updates don't have
a root part, installing a remote /usr client will take considerably
less time than a standalone.

 Basically, the server's /usr filesystem is exported to the client which mounts
 it, and the clients get all the root parts by using installp.

  The root parts of the lpps/ ptfs get applied during the boot time. Supposing
  you apply a new ptf to the server, you can get install the root part on
  the client by taking the following path in SMIT:
  smit installp
    Remote /usr Client Management
      Install/ Update this Client from Remote /usr

I got it from tesla.ee.cornell.edu and it compiled fine on

This is what I used:

CAEN is a localism (it's the name of this place).

AIX does not like

so you'll be making some of those

depending on the version of mh you have.

This problem is caused by goofiness in the printer colon file used to create 
the virtual printer. The relevant entries are "ia" and "ic". These are the 
entries that handle passing the flags to "pioformat", which is the program that
actually preformats the data before it's sent to the printer.


:274:ia::%Ide/pioformat -@%Idd/%Imm -!%Idf/piofpcl -l%IwL -w%IwW %f[bgijpstuvxzIJLOQXZ]
:275:ic::%Ide/pioformat -@%Idd/%Imm -!%Idf/piofpcl -l%IwL -w%IwW -X '' %f[bgijpstuvxzIJLOQXZ]

If you change these two lines where the "%f" is to include a "Y" in the string,
it should work OK.

BTW, the command to use is "smit chvirprt"

Summary: perl script to get rmt talking to the non-ibm world
Organization: Ntl Center for Atmospheric Research, Atmospheric Chemistry
Date: Wed, 11 Nov 1992 21:16:47 GMT

As I posted earlier, the rmt command on the RS6000/AIX3.2 passes ioctl
requests directly to the local tape drive.  Since the ibm ioctl numbers
don't correspond to those usually used on other systems for the rmt
command, rmt fails from hosts not consciously making an exception for
the ibm ioctl call numbers.  The following perl script, if installed in
the place of the symbolic link /etc/rmt, will intercept and convert these
ioctl calls. (remember that /bin/perl must either be the perl executable
or must be a symbolic link to the executable).


#!/bin/perl
# Wrapper to convert input rmt requests to
# AIX 3.2 ioctl numbers.  We pass on all commands we don't understand

I saw this same problem (3.2.2). I used rrestore (not restore) to
restore the backup. Admittedly, this is a rather roundabout way of
doing things when you're invoking the restore on the host with the
tape drive. I don't think  restore is actually "restore" in the
rdump sense (it's a different format). I wasn't even able to use
restore when I ran backup-by-inode. I still had to use rrestore.

Sure it does. You just need to think about it a little bit beforehand. 

First and foremost, to avoid the problems with locking, permissions, etc. etc.,
make sure any given user's mail is only *delivered* to one system - preferably 
the one serving /var/spool/mail, since that's the most efficient and totally
avoids any delivery locking problems.

This can easily be accomplished using a global alias table which is propagated
nightly (or whatever) by a cron job. This has been in use here for years, and
it's wonderful.

Ah, AIX is doing it differently from the rest of the world. Well, if you can't
make AIX do it "right", you can make the Suns adapt to it. Or you can avoid all
the conflicts by having the mail server do the delivery.

>   Ok you say.. change the permissions to 660, owner=user and group=mail..
>   WAIT... there is NO group mail on a SUN!

So create one - what's the big deal? On AIX mail is group 6; on Suns group 6
is news. If you don't run news on your Suns, this doesn't matter. If you do, 
news really doesn't care which group number it uses, just change it.

I was going to address all your points one by one, but the message was too
long (I'll email it if you want, though). They're all easily worked around, 
and when I got to the end I realized that you're 90% of the way to having a 
central mail spool work nicely anyway, with your combination of NIS aliases 
and hiding originating addresses. The only remaining step is to have every-
one's mail delivered on the existing mail hub and then mount its spool area 
everywhere through NFS.

Keywords: X, xrdb, xterm
Organization: Department of the Geophysical Sciences, University of Chicago
Date: Tue, 10 Nov 1992 18:50:15 GMT

Hello all,

I've been configuring X11R4 (the version that came with AIX 3.2.0), but
have encountered some minor problems.  I wrote a script to start the X
server and a few default clients (ala startx), but while the X server
always comes up fine, occasionally some of the clients (in particular,
xrdb) never do.  For example, consider the following which is taken
from a script which starts the default X clients:

...

#
# Load default resources
#

if [ -f $HOME/.Xdefaults ]; then
    xrdb -load $HOME/.Xdefaults
else
    xrdb -load $XHOME/lib/Xdefaults  # XHOME == /usr/lpp/X11, which as already
fi                                   #   been defined elsewhere

#
# Start default clients
#

aixterm &
xclock -geometry 100x100-5+5 &

# Start up window manager last

mwm


The problem I've been having with this is that xrdb runs, buts doesn't
load the resources from the appropriate file.  Aixterm, xclock and mwm
all start properly, however.  If I run xrdb manually from the aixterm
that starts up, though, xrdb works fine.  The problem occurs
regardless of when xrdb is run; if I start aixterm and xclock before
xrdb, aixterm and xclock start, but xrdb still fails to run properly.

Another problem I've encountered is with xterm (not aixterm).  If I start
an xterm in the script above, the xterm will start up, but the <ENTER>
key on the HFT does not function properly.  I have to type 'reset ^J'
(I have to use ^J, control-J, to enter the command) in order for the
<ENTER> key to function properly.  The same problem occurs if the xterm
is started from mwm's root menu.  If I start the xterm on a command
line from within another [ai]xterm, the xterm functions properly.

Anyone have a similar experience, and more importantly, anyone know
how to fix it?  The system is running AIX 3.2.0, X11rte 1.2 with
updates U402023, U402376, U402470, U402659, U402819 applied.  I'm
using the xterm and xrdb executables that came with the OS (that is,
not executables compiled from source in /usr/lpp/X11/Xamples).

Thanks for any assistance.

I'm just getting started using SLIP, and am also having some problems
(many of which are probably due to my inexperience).

Every time I bring up SLIP, I re-establish the route; it doesn't seem
to work otherwise.  Again probably need to investigate, but instead just issue:

route -n -f
chdev -l inet0 -a route=default,9.5.22.5

(substitute your own default route)
(don't ask me why I use "route" one time, and "chdev" the other when "route"
 would do both... it's working!)

Now, anyone know how to write a long and involved chat script, where the
other end (at one point) issues three separate messages, and the RISC 6000
only responds to the last of them?
