1.1   Alarm Description

This alarm is raised when the distribution of masters has been frozen and the automatic master re-election procedure has been blocked. This can only happen when Ericsson personnel is running advanced recovery and troubleshooting actions on a CUDB system.

The possible alarm causes and the corresponding fault reasons, fault locations and impacts are described in Table 1.
