| The Product is called OpenM by Intersystems. It's basically a database used
by the VA hospitials for their patient records.

| Try stopping the CFMD and Cluster failover manager before you install the application. I have seen instances
where installing or upgrading and application after cluster software is installed causes some
of the service .exe files get deleted.

I don't think the problem is due a deleted *.EXE file, because (1) I see the
same behavior after re-installing Clusters and (2) everything seems to works
after restarting the "Cluster Failover Manager" (which stops by itself).
Like I stated initially, it looks like a timing problem.
I don't think it's an interaction with any other software on the system because
we've installed the same configuration at several sites. At some sites, we see
this problem, at others, we don't. What is different is the Domain evironment.
I suspect that it has something to do with Domain and/or Server Browsing taking
a long time. We also have a product called UltraBac that checks for Clients to
backup when the application starts. Typically, this takes 10-15 seconds. At
the sites having the problem, this takes ~4 minutes. Also, I noticed that
User Manager for Domains takes longer than usual. The sites that see this
behavior have several trusted and trusting domains, across the country, as well
as a rather large distributed WINS database. Other sistes, not seeing this
behavior, are using an isolated domain.

| 707.5 | More of the Same... | CIVPR1::WHITEDA | | Wed Apr 09 1997 19:36 | 31 |
| Donna (and others),
It seems that this problem is hard to reporduce has well. We have
installed about 10 sites thus far and 5 of these sites have this
problem. we try to reporduce the problem in our lab (where we have
identical equipment) with no success.
Also, we have found that this problem starts has soon has clusters is
installed. The problem is the same, that if a server comes On-Line
and it's partner server is powered off then it Goes into the loop Mike
Mentioned in the first note.
Even if the only thing in the failover group is the disks, the server
will not pick them up. On a working Cluster, it gives the waiting Message,
but then continues with the system loadup.
Also, at our Muskgogee, OK site we found logging into NT as soon as
the prompt appeared, the first server up to pick the disk and services.
If the systems were booted and just let set for a few minutes, neither
system would pick up the disks (and services).
Could this possiblly be due to bad terminators on the Scsi cables ?
this is about the only thing I can guess, but still we can't produce
it. Is there a way to keep clusters from searching for the other server
and start the loadup automatically ?
TIA

| 707.6 | Isolating private network prevents problem | CIVPR1::SIMMONS | Mike Simmons (301) 918-5597 | Tue May 06 1997 12:06 | 19 |
| We've installed about 30 sites so far, and we've seen this problem at about half
of them so far. All the sites' installations are the same. What is different
is the existing domain and network configuration. On a fairly recent install,
we had seen the problem with the BDC & PDC on the existing network. We moved
the BDC to the same hub as the Cluster servers and put in the same subnet and
removed it from the rest of the network. When we did this, the problem went
away. We finally were able to reproduce the problem in our lab. We have the
WINS client on both network cards running TCP/IP on the same subnet, both
connected to the public network. We started to see the problem when I noticed
the WINS binding order under Server was opposite as that for Workstation. (One
was 1,2, the other was 2,1) When I made the order 1,2 for both, I started
seeing the problem. After consistently seeing the problem, I could avoid the
problem by preventing the two network cards from seeing each other, in other
words, by isolating the private network. I could do this by physically
disconnecting thhe 2nd hub from the public network, or by puuting the 2nd cards
on a separate subnet and not providing a gateway. We are now in the process of
putting NetBEUI only on the 2nd (private) cards and TCP/IP + LAT on the 1st
cards. We need to make this change on the next wave of sites to verify that
this universally fix this problem.
