Then why are they paging you? Haven't
they seen the problem before? :-)
Seriously Ray, I'm as confused as I
can be about this. This is 7.1.4, right? My only suggestion is that
you get an nvserverd trace and call Support.
Create a /usr/OV/bin/netnmrc.pre file
which contains the line,
export
NVSERVERD_TRACE_TEC_EVENTS=TRUE
and then restart everything. You'll
need to go all the way down, with "ovstop nvsecd" and come up
with "/etc/netnmrc"
I don't know whether this log will be
helpful or not, quite frankly, but I have no idea where else to look for
an answer at this time.
I don't see how nvserverd can have the
address wrong on shutdown, if he's had it right all the time before. Once
the address and name of the NetView box have been determined for the first
time, nvserverd sets a flag to mark that and keeps them in storage. He
shouldn't try to find a new address once the flag is set. So I am mystified
as to what is going on here.

It was not an isolated event.
That was the 3rd weekend (3rd NetView shutdown) since the interface has
been added and the 3rd occurrence of the problem.

So this is not an isolated event? Or is that what you are waiting
to determine?

James,
I found some inconsistencies in the NetView server host file. I also found
a misspelling for the NetView server hostname in the TMR's host file (although
that should not affect the source).
I was reading the message from the 3.9 TEC Console (java GUI). This is
what our operations folks monitor. Here is the message from wtdumprl:
Nvserverd_Event;source=nvserverd;origin=0.0.0.0;hostname=UNKNOWN;adapter_host=UNKNOWN;date="05/30/04
01:03:47";status=OPEN;severity=
FATAL;msg="nvserverd is ending";END
DNS is not shutdown. However - the host files are read by the server first.
The message is received by the TMR very quickly. Other events appear correctly.
Let's see what happens this Sunday.
Thanks.
