CLOUD_NETCONFIG_MANAGE in a HA Cluster
This document (7023633) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Linux Enterprise High Availability Extension 12
Situation
If the version is 1.3 or higher, it is no longer necessary to suppress the management of network interfaces by the cloud network plugin. If the version is lower than 1.3, we suggest to update package cloud-netconfig-azure to the latest available version.

For cloud-netconfig-azure package version lower than 1.3:
In a HA Cluster in a Cloud Enviroment a configured IP Address sometimes disappears resulting in a restart or sometimes even a resource migration - see Resolution section.
Resolution
/etc/sysconfig/network/ifcfg-eth0
CLOUD_NETCONFIG_MANAGE="yes"
is set. This has to be set to
CLOUD_NETCONFIG_MANAGE="no"
Cause
In a HA Cluster normally the only way for a client to connect to the Cluster is via an IP from the cluster that is dynamically set by the Cluster and not in the configuration file.
As such the two concepts conflict with each other.
In a HA Cluster Setup it is recommended to set the parameter to
NO
to ensure that the IP wont be touched.
