Description: This message occurs when a Distributed Block Store (DBS) event related to the database ensemble occurs, such as the inability to reach the database in a node.
Corrective Action: (None).
Syslog Message: A DBS ensemble event %s of type %s occurred for Service ID %u on node %u/%s. Drive ID = %u/%s. Event ID = %u.
Parameters: evtMessage (STRING): Description of the DBS event, including context details.
evtType (STRING): Type of the original DBS event.
serviceID (INT): Service ID that identifies the associated DBS service. It is 0 if there is no associated service.
nodeID (INT): Node ID number of the associated node. It is 0 if there is no associated node.
nodeUuid (STRING): Generated Universal Unique Identifier (UUID) of the associated node. It displays zeroes if there is no associated node.
driveID (INT): Drive ID number of the associated drive. It is 0 if there is no associated drive.
driveUuid (STRING): Generated UUID of the associated drive. It displays zeroes if there is no associated drive.
evtID (INT): DBS event ID number.
evtDetails (STRING): Specific details of the DBS event. It displays as a string, in JSON format, or is empty.

Severity: ALERT
Description: This message occurs when the Distributed Block Store (DBS) detects the database connection to less than half of the ensemble nodes (of 3 or 5 total) is not available. The database still has quorum and is operational.
Corrective Action: Verify power for all nodes and their network connectivity. Wait 10 minutes and check that the fault status has changed to Resolved. If the condition persists, contact NetApp technical support.
Syslog Message: DBS has lost network connectivity or power an ensemble node. Cluster fault type %s, fault ID %u, status %u. %s
Parameters: cfType (STRING): DBS cluster fault type of the associated object.
cfID (INT): DBS cluster fault ID number associated with the fault.
cfStatus (INT): Current status of the cluster fault. 1 = New (just reported), 2 = Existing (updated), 3 = Resolved (closed).
cfDetails (STRING): Description of the degraded ensemble.
cfExtSrc (STRING): DBS cluster fault externalSource label created by the CreateClusterFault API command and attached to the fault for testing purposes.
