Cluster Services fail on boot because of Firewall (HEARTBEAT, OPENAIS)

This document (7007820) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 10
SUSE Linux Enterprise Server 11


Configured and tested network based cluster services fail on boot. The Firewall settings are checked and verified. Still the services fail.


Reason for this is that the Firewall starts in two stages, Number one
which closes every port and and Number two

which opens defined ports again. And the cluster service starts in between these two stages.

The solution is to disable Stage one if security permits
