Environment

2.1

2.2

Cause

The airgap server FQDN is missing from the TCA Control Plane node database.
This could happen after cluster certs are renewed using manual/automated workarounds provided.

Resolution

Update Airgap FQDN for management cluster in TCA-CP DB

1. SSH login to the TCA-CP where cluster is configured.
   
   
2. Connect to the mongo database using the following command:
   mongo hybridity
   
   
3. Verify the record exists:
   db.ApplianceConfig.find({"config.clusterName": "<CLUSTER_NAME>"}).pretty();
   
   
4. Check the entries for the cluster, confirm the Airgap entry is missing or incorrect.
   
   
5. Run the following command on the mongo shell to update the config.airgapFqdn for the cluster(s):
   db.ApplianceConfig.update({"config.clusterName": "<CLUSTER_NAME>"}, {$set: { "config.airgapFqdn": "<AIRGAP_FQDN>" }});

Note: In the above commands, update the <CLUSTER_NAME> and <AIRGAP_FQDN> values appropriately

 

Examples:

Before adding airgap FQDN:

{ "_id" : ObjectId("63ee0fced91947fc27f9b96d"), "config" : { "url" : "[https://10.0.0.1:6443|https://10.0.0.1:6443/]", "clusterName" : "<CLUSTER_NAME>", , "UUID" : "a7640b6b-f3b5-4a6d-98f3-b19e16c6dbe2", "version" : "1.22", "kubeSystemUUID" : "9f24e947-61bc-46c3-874f-2a430554befb", "clusterType" : "WORKLOAD" } , "section" : "kubernetes", "enterprise" : "HybridityAdmin", "organization" : "HybridityAdmin", "lastUpdated" : ISODate("2024-03-20T07:59:24.211Z"), "lastUpdateEnterprise" : "HybridityAdmin", "lastUpdateOrganization" : "HybridityAdmin", "lastUpdateUser" : "HybridityAdmin", "creationDate" : ISODate("2023-02-16T11:13:18.802Z"), "creationEnterprise" : "HybridityAdmin", "creationOrganization" : "HybridityAdmin", "creationUser" : "HybridityAdmin", "isDeleted" : false }

 After updating the changes in DB:
