Resolving node detection and cluster creation issues
If you encounter issues during initial cluster creation, read the following sections for possible resolutions.
- Multicast is enabled on the network switch that the cluster nodes are connected to.
- All of the following components are reachable from the network switch:
- Default gateway
- DNS server
- NTP server

- The cable connecting the laptop to the node has an issue.
- The node's management NICs are not enabled in the BIOS.
- Replace the cable.
- Verify that the node's management NICs are enabled in the BIOS. Checking the BIOS requires a VGA terminal to access the console.
No Node is Detected
Possible cause
The network switch configuration prevented mDNS from being received/transmitted.
Resolution
Attempt to connect the laptop to another Node's management port to narrow down which network cable, switch port, or Node network port has an issue so you can resolve it.
Some Nodes are Not Displayed
Possible cause
The Node’s network connection has an issue.
Resolution
Check the Node’s cable connection, network switch port or the Node’s network interface. Check the indicator lights that may help you identify the issue.
Cluster Creation Process is Stuck
If the Cluster creation is stuck, investigate the listed connectivity issues.
- A connectivity issue with the default gateway that was entered.
- A connectivity issue with the NTP server.
Resolution
Once the connectivity issue is resolved, setup should proceed.
Cluster Creation Succeeds with Warnings
Cluster creation can succeed but still issue warnings.
- Ping to gateway failure - If this failure is unexpected, contact IBM Support to update the Cluster bond0 gateway.
- Ping to DNS failure - If this failure is unexpected, edit the Cluster DNS on the Cluster Settings page in the UI.
