In this Document   APPLIES TO: Oracle Database - Enterprise Edition - Version 11.2.0.3 and later Oracle Net Services - Version 11.2.0.4 to 11.2.0.4 [Release 11.2] Oracle Database Cloud Schema Service - Version N/A and later Oracle Database Exadata Cloud Machine - Version N/A and later Oracle Cloud Infrastructure - Database Service - Version N/A and later Linux x86-64 SYMPTOMS Dynamically added new disks to storage using udev rules(as per the docs note 414897.1, 1528148.1, 371814.1 etc). During start_udev, udev has deleted the public network interface and this caused the listener to crash, and clusterware moved all services, scan listeners and the VIP on node 1 to node 2. CHANGES  Trying to add disk to storage using udev CAUSE  udev has deleted the public network interface. SOLUTION As per RHEL you are advised to set HOTPLUG="no" for the network configuration scripts. Add HOTPLUG="no" to the ifcfg-eth0 (public), ifcfg-eth1 (private) and ifcfg-eth2 (backup) network config files in /etc/sysconfig/network-scripts directory.
