Hi Renar,
the tsctl problem is described in APAR IV93896
https://www-01.ibm.com/support/docview.wss?uid=isg1IV93896
You can easily find out if your system has the problem: Run "tsctl
shownodes up" and check if the hostnames are valid, if the hostnames are
wrong/mixed up then you are affected.
This APAR has been fixed with 5.0.2
Mit freundlichen Grüßen / Kind regards

HI Tomer,
send my work around wrapper to Renar.. I've seen to less data to be sure,
that's the same (tsctl shownodes ...) issue
but he'll try and let us know ..

Hi,
I remember there was some defect around tsctl and mixed domains - bot sure
if it was fixed and in what version.
A workaround in the past was to "wrap" tsctl with a script that would
strip those.
Olaf might be able to provide more info ( I believe he had some sample
script).

Hallo All,
in this relation to the Alert, i had some question about experiences to
establish remote cluster with different FQDN?s.
What we see here that the owning (5.0.1.1) and the local Cluster (5.0.2.1)
has different Domain-Names and both are connected to a firewall. Icmp,1191
and ephemeral Ports ports are open.
If we dump the tscomm component of both daemons, we see connections to
nodes that are named [hostname+ FGDN localCluster+
FGDN remote Cluster]. We analyzed nscd, DNS and make some tcp-dumps and so
on and come to the conclusion that tsctl generate this wrong nodename and
then if a Cluster Manager takeover are happening, because of a shutdown of
these daemon (at Owning Cluster side), the join protocol rejected these
connection.
Are there any comparable experiences in the field. And if yes what are the
solution of that?
Thanks Renar

This sounds like a different issue because the alert was only for clusters
with file audit logging enabled due to an incompatibility with the policy
rules that are used in file audit logging. I would suggest opening a
problem ticket.
Thanks,

Hallo All,
are there any news about these Alert in witch Version will it be fixed. We
had yesterday this problem but with a reziproke szenario.
The owning Cluster are on 5.0.1.1 an the mounting Cluster has 5.0.2.1. On
the Owning Cluster(3Node 3 Site Cluster) we do a shutdown of the deamon.
But the Remote mount was paniced because of: A node join was rejected.
This could be due to incompatible daemon versions, failure to find the
node in the configuration database, or no configuration manager found. We
had no FAL active, what the Alert says, and the owning Cluster are not on
the affected Version.
Any Hint, please.
