The reason there is no cluster information was that there was an identification rule on u_cmdb_ci_ibm_cluster with identification attribute cluster_id.
On the discovered cluster this field was not populated.
To seethe identification rules:
- Navigate to CI Identifiers
- Look for records that applies to u_cmdb_ci_ibm_cluster
- Change the identification rule to rely on the name attribute
- Check to see if the information is shown correctly on the right pane
If name is not sufficiently unique for this kind of cluster, cluster_id may be brought back, but then the probe/sensor must populate this field.
