SNMP Name | ptSlotDatabaseClusterMalfunction |
Description | The database cluster is not functioning as expected. Either one or more cluster nodes are unreachable, or the cluster status does not match the configuration information that the user provides. |
Application | Slot Monitor |
Action | See the following Recommended Actions. |
If this alarm is raised because a cluster node is unreachable, see the following steps:
If all nodes do not successfully ping the other nodes on port 7000, reconfigure the cluster with IPv4 or IPv6 addresses (or matching hostnames) that belong to the network interface pkt0.
To add the IPv4 and IPv6 addresses, log in to the WebUI and click IP Networking > Routing IP Network.
If all nodes do not successfully telnet the other nodes on port 7000, log in to the WebUI and click IP Networking > Firewall to restart the firewall.
If this alarm is raised because the cluster status does not match the configuration information provided at initial configuration, contact Customer Support because the cluster may need to be reconfigured.
Cassandra restarts after the configuration completes.
