Duplicate Host ID

UI Column

Duplicate Host Id

Logged As

NODE_ALARM_DUPLICATE_HOSTID

Meaning

Two or more nodes in the cluster have the same host ID.

Resolution

Multiple nodes with the same host ID are prevented from joining the cluster, in order to prevent addressing problems that can lead to data loss. To correct the problem and clear the alarm, make sure all host IDs are unique and use the maprcli node allow-into-cluster command to un-ban the affected host IDs.
