Hey Jeff, all @ 3000-l,
I am guessing that if you have ODIMXE9B installed that this is a system
running MPE/iX 7.0.
I don't know what Tivoli does internally when it talks to the 3000 - PING or
SNMP or other ?
You did not mention which patches are installed... I would suggest the 2
that might have the most impact on the MPE network code and this probelm
are:
NSTHD01 for C.70.00
SNMGDT5 for C.70.00
... and that you possible are seeing:
SR: 8606-206689
FROM: SNMGDD4
SNMP VolumeTable lookup ties up CPU
... If Tivoli uses SNMP.
Regards,
James Hofmeister

Hello all -
I'm having a problem with one of our hp3000's and I'm a little stumped.
Our company uses Tivoli to check to see if a system is 'up' (which I think
to Tivoli that means it responds to a ping or a series of pings). I have
an hp3000 that occasionally does not respond. When this happens, our
trouble ticket and paging mechanism is triggered, and the support folks are
in a state of nervousness until someone actually logs onto the system and
sees it's still humming along.
I initially thought it must be a network problem, but I've found something
that has me questioning that. We use the Lund product to gather
performance data, and it takes its performance 'snap shot' every 5
minutes. It's pretty good about being on time...sometimes the timestamp on
one collection cycle is 6 minutes after the last one, but most of the time
it's every 5 minutes. Well, during the time we're having the problem, it
skips its collection cycle completely, so there's 10 minutes between
cycles. This leads me to believe that there's something going on on the
system that may be causing the problem.
Does anyone have any ideas as to what to look at?
Here's some more info:
The problem has happened 4 times in the month of January, and 3 times in
the month of December. The first occurrence was 12/8. I'm guessing the
problem lasts for maybe 3 minutes (based on console history). The console
does not show any messages during this time. The messages right before the
problem starts are 'normal'. Same with the messages after the problem is
cleared up. It looks like normal processing picks right back up.
We put one patch on on 12/6 which looks unrelated to this problem.
ODIMXE9B Online Diagnostics version A.75.03 - xt and fwu disk enclosure
support
This is a test system and the problem has only occurred during the evening
hours or early morning hours. During the evening we run a Veritas network
backup, and I can tell one was running during each occurrence of the
problem when it happened in the evening. However, it's processes are
always in the cs queue. I'm assuming that the Lund collection process
fires off in the linear queue (need to verify that with Lund however), so
it should get cpu time over the backup. Also, we've been running the
Veritas backup for years without these problems occurring.
For the morning problems, the one constant that I see in the performance
data (the '10 minute snapshot performance data') is the NFT process. It's
in the linear queue (bs), but it never shows up as a 'hog process'. In the
mornings we do a lot of dscopying to this system, and also a lesser amount
from this system to another hp3000. But again, we've been running these
processes for a long time without problems.
I've looked through the network logs and the system logs, and I don't see
anything unusual compared to when the system was not having a problem.
I've also noticed that on occasion it takes longer than normal to get to
the initial Logon Prompt for this system.
Any ideas would be greatly appreciated! Thanks- Jeff
