panic[cpu0]/thread=40037e60: Failfast: Aborting because "ucmmd" died 30 seconds agoDescription:
A component that the UCMM controls returned an error to the UCMM during a reconfiguration.Cause:
The most common causes of this problem are as follows:
The license for Veritas Volume Manager (VxVM) is missing or has expired.
The ORCLudlm package that contains the Oracle UDLM is not installed.
The version of the Oracle UDLM is incompatible with the version of Sun Cluster Support for Oracle RAC.
The amount of shared memory is insufficient to enable the Oracle UDLM to start.
A node might also panic during the initialization of Sun Cluster Support for Oracle RAC because a reconfiguration step has timed out. For more information, see Node Panic Caused by a Timeout.Solution:
For instructions to correct the problem, see How to Recover From a Failure of the UCMM or a Related Component.
When the node is a global-cluster voting node of the global cluster, the node panic brings down the entire machine. When the node is a zone-cluster node, the node panic brings down only that specific zone and other zones remain unaffected.
