Verify

In this step you will:

• Run a series of verification checks to ensure the upgrade from TOS Classic to TOS Aurora was successful.

Verification Checks

Checks on Central (Main) Cluster Only

Perform these checks only if you have just installed a central cluster.

1. In your browser, go to URL https://<IP>, where <IP> is your primary VIP for on-prem or load-balancer IP/domain for cloud deployments.

   The TOS Aurora login page will appear. If not, check that you are using a supported browser.

2. Log into TOS Aurora with an admin user/password that you have been using until now for TOS Classic. If a warning message is shown regarding the site security certificate, 'accept the risk' and continue to the site.

Checks on Central and Remote Collector Clusters

Perform these checks in all cases.

1. Get root privileges.

   Either use your own password,

   [<ADMIN> ~]$ sudo su -

   sudo su -

   or use the root password (RHEL/Rocky Linux only),

   [<ADMIN> ~]$ su -

   su -

2. Check tos status.

   [<ADMIN> ~]# tos status

   tos status

   

   Everything should appear OK. If any errors are listed, check the logs of the pods / databases specified in the error.

3. Check for errors by running tos status history.

   [<ADMIN> ~]# tos status history

   tos status history

   Everything should appear OK. If any errors are listed, check the logs of the pods / databases specified in the error.

4. Check for errors by running tos report.

   [<ADMIN> ~]# tos report

   tos report

   Everything should appear OK. If any errors are listed, check the logs of the pods / databases specified in the error.

5. Check Kubernetes status.

   [<ADMIN> ~]# systemctl status k3s

   systemctl status k3s

   

   Check that two lines - loaded and active - appear.

6. Check Kubernetes pod status.

   [<ADMIN> ~]# kubectl get pods

   kubectl get pods

   All pods will be listed.

   If there are pods with a status other than running or completed, this indicates a problem

   Check that all pods have all their containers ready. Ready containers are displayed as m/n where m is the number of ready containers and m is the total number of containers in the pod. If m and n are the same value for a pod (e.g. 1/1, 2/2, 3/3) all of its containers are ready. If you see values like 1/2, 2/3, and a pod status of ready, this indicates a problem.

7. If problems were found with the pods in the previous check, get more information:

   [<ADMIN> ~]# kubectl logs -f <POD NAME>

   kubectl logs -f <POD NAME>

   [<ADMIN> ~]# kubectl describe pod <POD NAME>

   kubectl describe pod <POD NAME>

Congratulations, your TOS Aurora installation was successful. You can now continue with the configuration.
