GDPS xDR and Takeover Prompt due to TCPIP restart

[Tobias Doerkes]

Hi again,
 
next question regarding xDR raised: When performing a restart of TCPIP on the 
controlling lpar due to network reconfiguration, GDPS throws a takeover prompt 
due to missing heartbeat for the xDR proxy server. 
 
So we wonder how other installations solved this problem. Do you perform a 
xdrstopcluster before restarting TCPIP?
 
Any help would be appreciated.

We have got a one K system configuration. But i think there should be a 

smarter solution than xdrstopcluster before restarting TCPIP.

We run 2 so don't run into this issue since the other then takes over as master 
if the master K goes down (including TCP/IP).
We have seen as we fire up the tests that K(s) need to be up when proxies come 
up or they just don't connect.  In production, 2 Ks for HA so no problem.
I'd discuss your situation with your GDPS team.
