Im a new sys
admin. I started this job in July, just before the new N-Class came
to replace the 987 as a development/production shadow machine and we
upgraded the production 969 to 7.0. Now weve got this perfectly
good 987 on our hands, and my boss is wondering if we can move it to
our out-of-state site and use it for disaster recovery. But we would
need to upgrade it to 7.0 in order to shadow (Shareplex) our
production machine to it, right? Can we even shadow to two different
machines in the first place?
John Clogg, Ron
Horner and John Burke reply:
7.0 will not
boot on any 9x7 Series system. There is, however, no technical reason
for it not working. HP marketing simply decided to try to goose up
sales of new systems by forcing the obsolescence of the 9x7s. [As of
HP World 2002, HP is still insisting it will not change this policy.]
6.5 is as far as you can go on a 9x7.
As for Netbase/Shareplex
shadowing to multiple machines, absolutely it can do that. Of course
youd need the license for the extra machine. Note that the
shadow machine can be on 6.5 even while the master machine is on
I have a question
regarding the build command. Last night I had a job fail because the
build for the file failed. The command BUILD
-384,21,F,ASCII was failing, complaining of no disc space.
What puzzled me was that DISCFREE showed more than 40 million sectors
free. Then when I removed the ,1,1 from the DISC parameter, the build
worked. I am just curious as to why. I know the ,1,1 has to do with
extents, but I never learned the reasoning for them, or what they

Church and Tom Emerson reply:
trying to allocate all the space in one extent (thats what the
1,1 means); i.e. one contiguous block of storage.
Undoubtedly, your disk is fragmented sufficiently that this was
What is the file
size limit for a RIO file? My system (6.5) gives me the FSERR 106
message when trying to build the file. I tried specifying the number
of extents and got the same result.
EXCEEDS MAXIMUM (FSERR 106)
Michael Berkowitz notes:
RIO files are
one of the few file types that are not in native mode, which means
they are limited to a half-Gb.
John Burke replies:
this a somewhat of a misleading error message. You have fragmentation
issues. Try DISC=550000,32,32 (the maximum
number of extents is 32) and see if that does not work. If it does
not, then you really have fragmentation problems (assuming you have
adequate total disc space) that you need to address either through a
total reload (ugh) or one of several software utilities that will do
I now have the
newest supported version of Samba running. I changed my Samba startup
jobs to match the supplied jobs. The problem is, how do I stop the
jobs with resorting to abortjob? The relevant line from the new job
(for nmb) is:
nmbd207.samba.sys -D -p 137
Lars Appel replies:
Try using the
pid files /SAMBA/SMB207/var/locks/?mbd.pid for kill. Samba 2.x
creates those .pid files automatically during startup.
Why is my system
clock running slow? We have a 979-200 on MPE/iX 6.0 PP2. It loses
about one minute per day.
Bill Cadier replies:
system does not have MPEKXY0 installed you should consider installing
it. This patch has been superseded a few times so if you have
MPELX38, MPELXG5, MPELXK9 or MPEKXR0 installed then you would have
MPEKXY0 too. None of these patches was on 6.0 PowerPatch 2.
If you already have one of
these patches then the problem could be hardware related so it might
be worth contacting your hardware support people to check that
Bob J. adds:
possibility was addressed by a firmware update. The text from the
current CPU firmware (41.33) update PF_CMHK4133 mentions:
(software maintained) loses time. The time loss occurs randomly and
may result in large losses over a relatively short time period.
Occurrences of the above problem have only been reported against the
HP 3000 979KS/x00 (Mohawk) systems. Software applications that
perform frequent calling of a PDC routine, PDC_CHASSIS, affect the
amount of time lost by the system clock. Your hardware support
company should be happy to update for you.
Tongue firmly in
cheek, Wirt Atmar notes:
guess would be relativistic time dilation effects as viewed by an
observer at a distance due to the fact that youre now migrating
off of the HP 3000 at an ever accelerating rate. My second guess,
although its less likely, would be that your machine has found
out that its about ready to be abandoned and is so depressed
that it simply can no longer work at normal speed. Weve
certainly kept this information from our HP 3000s. Theres just
no reason that they need to know this kind of thing at the moment.
And, in the same vein,
Bernie Sherrard adds:
Look at the
bright side. At a loss of one minute per day, you wont get to
12/31/2006, until 2 AM on 1/2/2007. So, you will get 26 hours of
support beyond everyone else.
Some time ago, I
recall seeing a reference to commands that would remount a DDS
cartridge, without the operator having to physically take the tape
out and put it back into the drive. I searched the Archives, but did
not find what I was looking for. What is the correct command?
Paul Courry replies:
DEVCTRL.MPEXL.TELESUP. Just type in the name without any
parameters and it will squirt back the instructions for use.
Stan Sieler adds:
to DEVCTRL, you might want to check out our free ONLINE program at www.allegro.com/software/hp3000/allegro.html#ONLINE
We are trying to
access a database on our old system using QUERY and it is asking for
a password. I have done a LISTF ,-3 on the database, but there is no
lockword listed (which I assumed would be the password). Where do I
find the password assigned to a database?
John Burke replies:
do not have access to the original schema and you want to know what
the password is, not just access the database, then sign on as the
creator in the group with the database, run DBUTIL.PUB.SYS and issue
the command SHOW databasename PASSWORDS
Mike Church and
Joseph Dolliver add:
If you just
want to access the database, log on to the system as the database
creator and, when asked for password, put in a ;
semi-colon and hit return.
We have a new HP laser
printer that will need to be accessed via our network and the 3000.
We dont have any LDEVs available. What process do I need to
follow to set up a new one? Do I set it up in SYSGEN and NMMGR?
John Burke and
Gary Jackson reply:
You do not
need either SYSGEN or NMMGR. You can use IOCONFIG and dynamically add
network printers. Also, as far as an LDEV, you will be able to choose
any number not currently used. This was all first documented in the

Autoinst, number 3 for FOS, SUBSYS, and PP3. It seemed to restore the
FOS correctly, SUBSYS went well (about 34 jobs), but when it got to
the part where it backs up the SL, XL, NL, it aborted because it
could not find the file AUTOGEN.INSTALL. It does not exist. Any
suggestions, besides call an expert?
