[Attach the host](https://cloud.ibm.com/docs/satellite?topic=satellite-attach-hosts) back to your Satellite location, but do not assign it. Later, after you complete these troubleshooting steps, you can [re-assign the host](https://cloud.ibm.com/docs/satellite?topic=satellite-assigning-hostshost-assign-manual) back to your Satellite location control plane or cluster.
4. SSH into the host machine.





2. Look up each location subdomain that you found in step 1. Check whether the IP address that resolves matches the host IP addresses that you found in step 1. If the host's DNS resolver does not resolve the subdomains to the expected IP addresses, ensure that your hosts have the [required minimum outbound connectivity](https://cloud.ibm.com/docs/satellite?topic=satellite-reqs-host-network-outbound).

nslookup <subdomain>
3. Use netcat on each location subdomain on port 30000 to test host connectivity. If any subdomain's netcat operation times out, ensure that your hosts meet the [host network requirements](https://cloud.ibm.com/docs/satellite?topic=satellite-reqs-host-network).

nc -zv <subdomain> 30000

Successful output:

Ncat: Version 7.50 ( https://nmap.org/ncat )

With a simpleselect, you can specify the following characteristics of a result set:



* The list of result columns from relations or lateral views that are part of the final result set. The result column list can be further redefined by using the following modifier keywords:



* DISTINCT: Eliminates all but one of each set of duplicate rows of the final result set.
* ALL: Retains all rows of the final result set, and does not eliminate redundant duplicates. It is the default.



* The FROM clause defines the list of relations or lateral views that are combined to derive a result set.
* The WHERE clause defines the way how relations and lateral views are filtered and joined to derive a result set.
* In its simplest form, the GROUP BY clause defines how rows that qualify for the final result set are grouped based on grouping expressions. Each group is represented by a single row in the final result set.
* The HAVING clause is used with the group by clause to filter out groups from the final result set.







 resultColumn 

A result column can be any expression that can optionally be associated with an identifier, which is a new name. By providing custom identifiers, you can control the column names that are used in the result data set written to Cloud Object Storage. See the following examples for such expressions:



* A column name from one of the relations.
* An expression that uses column names from one or multiple relations.
* Arithmetic expressions that perform calculations.







 Group by clause 



 groupByClause 





 groupingSet 

More complex group by clauses use so called grouping sets to provide more insights into the set of rows grouped by a grouping expression.

Grouping sets are best explained by using examples. The following set examples use values clauses to define result sets for group by operations. For more information about the values clause, see [valuesClause](https://cloud.ibm.com/docs/sql-query?topic=sql-query-sql-referencevaluesClause).

In the following example SQL query, sales data is grouped per year and quarter.

Debugging app deployments 

Virtual Private Cloud

Classic infrastructure

Review the options that you have to debug your app deployments and find the root causes for failures.

Before you begin, ensure you have the [Writer or Manager IBM Cloud IAM service access role](https://cloud.ibm.com/docs/openshift?topic=openshift-userschecking-perms) for the namespace where your app is deployed.



1. Make sure that you review the [common scenarios where you might need to modify your apps](https://cloud.ibm.com/docs/openshift?topic=openshift-plan_deployopenshift_move_apps_scenarios) so that you can deploy them on Red Hat OpenShift clusters.
2. Look for abnormalities in the service or deployment resources by running the describe command.

oc describe service <service_name>
3. [Check whether the containers are stuck in the ContainerCreating state](https://cloud.ibm.com/docs/openshift?topic=openshift-readonly_nodes).
4. Check whether the cluster is in the Critical state. If the cluster is in a Critical state, check the firewall rules and verify that the master can communicate with the worker nodes.
5. Verify that the service is listening on the correct port.



1. Get the name of a pod.

oc get pods
2. Log in to a container.

oc exec -it <pod_name> -- /bin/bash
3. Curl the app from within the container. If the port is not accessible, the service might not be listening on the correct port or the app might have issues. Update the configuration file for the service with the correct port and redeploy or investigate potential issues with the app.

curl localhost: <port>



6. Verify that the service is linked correctly to the pods.



1. Get the name of a pod.

oc get pods
2. Log in to a container.
Ensure that you are using the latest version of MotionPro. For more information, see [Prerequisities](https://cloud.ibm.com/docs/iaas-vpn?topic=iaas-vpn-standalone-vpn-clientsstandalone-prereqs).
4. Toggle your SSL VPN access from on to off, then off to on.
5. Try three different VPN endpoints in different regions. For more information, click [Available VPN endpoints](https://cloud.ibm.com/docs/iaas-vpn?topic=iaas-vpn-available-vpn-endpoints).
6. If you have exhausted these steps and are still running into the issue, create an [IBM Support case](https://cloud.ibm.com/unifiedsupport/cases/form).

Both the project and bucket must be in the same region. In addition, be sure that the resiliency is set to regional.
3. If the error message shows NotFound : Sink not found, then your destination app or job is not available. Run the [ibmcloud ce app list](https://cloud.ibm.com/docs/codeengine?topic=codeengine-clicli-application-list) command or the [ibmcloud ce job list](https://cloud.ibm.com/docs/codeengine?topic=codeengine-clicli-job-list) command to make sure that your destination app or job exists. If the app or job doesn't exist, create the application with the [ibmcloud ce app create](https://cloud.ibm.com/docs/codeengine?topic=codeengine-clicli-application-create) command or create the job with the [ibmcloud ce job create](https://cloud.ibm.com/docs/codeengine?topic=codeengine-clicli-job-create) command.



If these solutions do not solve your issue, retrieve the logs of the Object Storage subscription for further debugging by using [IBM Log Analysis](https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-mm-cos-integration) for log management capabilities.

If these solutions do not solve your issue, try one of the resources in [getting support](https://cloud.ibm.com/docs/codeengine?topic=codeengine-get-support).
In the spec.selector section of the LoadBalancer service, ensure that the <selector_key> and <selector_value> is the same as the key/value pair that you used in the spec.template.metadata.labels section of your deployment YAML. If labels don't match, the Endpoints section in your LoadBalancer service displays none and your app is not accessible from the internet.
3. Check that you used the port that your app listens on.





4. Check your NLB service and review the Events section to find potential errors.

oc describe service <myservice>

Look for the following error messages.

Clusters with one node must use services of type NodePort
: To use the NLB service, you must have a standard cluster with at least two worker nodes.

No cloud provider IPs are available to fulfill the NLB service request. Add a portable subnet to the cluster and try again.
: This error message indicates that no portable public IP addresses remaining to be allocated to your NLB service. Refer to [Adding subnets to clusters](https://cloud.ibm.com/docs/openshift?topic=openshift-subnetssubnets) to find information about how to request portable public IP addresses for your cluster. After portable public IP addresses are available to the cluster, the NLB service is automatically created.

Requested cloud provider IP <cloud-provider-ip> is not available. The following cloud provider IPs are available: <available-cloud-provider-ips>
: You defined a portable public IP address for your load balancer YAML by using the loadBalancerIP section, but this portable public IP address is not available in your portable public subnet. In the loadBalancerIP section your configuration script, remove the existing IP address and add one of the available portable public IP addresses. You can also remove the loadBalancerIP section from your script so that an available portable public IP address can be allocated automatically.

No available nodes for NLB services
: You don't have enough worker nodes to deploy an NLB service. One reason might be that you deployed a standard cluster with more than one worker node, but the provisioning of the worker nodes failed.



1.
1. Verify that all hosts in your Satellite control plane show a State of assigned and a Status of Ready by running ibmcloud sat host ls --location <location_ID_or_name>.
2. If all hosts show the correct state and status, the DNS record for your location is not yet created. This process can take up to 30 minutes to complete after all hosts are successfully assigned to your location.
3. If one or more hosts do not show the correct state or status, see [Debugging host health](https://cloud.ibm.com/docs/satellite?topic=satellite-ts-hosts-debug).







 R0015, R0016: Host issues 

Location message
: R0015: Could not assign hosts because no hosts are available. Attach more hosts to the location and try again. For more information, see the docs: '[http://ibm.biz/sat-loc](http://ibm.biz/sat-loc)'
: R0016: Unexpected error occurred after assigning host. To debug the host, see '[http://ibm.biz/sat-host-debug](http://ibm.biz/sat-host-debug)'. If you still have issues, contact IBM Cloud Support and include your Satellite location ID.

: [Attach more hosts](https://cloud.ibm.com/docs/satellite?topic=satellite-attach-hosts) to the location. If you attached hosts that are not showing up as available, see [Debugging host health](https://cloud.ibm.com/docs/satellite?topic=satellite-ts-hosts-debug).





 R0023, R0101: Wait for location to be ready 

Location message
: R0023: Wait while Satellite sets up the location control plane.
: R0101: The Satellite location has clusters in the middle of an operation. Wait for them to finish and check back later.

Steps to resolve
: Wait for the location control plane to finish setting up and check back later.
Get the name of a pod.

kubectl get pods
2. Log in to a container.

kubectl exec -it <pod_name> -- /bin/bash
3. Curl the cluster IP address and port of the service.

curl <cluster_IP>:<port>
4. If the IP address and port are not accessible, look at the endpoints for the service.



* If no endpoints are listed, then the selector for the service does not match the pods. For example, your app deployment might have the label app=foo, but the service might have the selector run=foo.
* If endpoints are listed, then look at the target port field on the service and make sure that the target port is the same as what is being used for the pods. For example, your app might listen on port 9080, but the service might listen on port 80.





6. For Ingress services, verify that the service is accessible from within the cluster.



1. Get the name of a pod.

kubectl get pods
2. Log in to a container.

kubectl exec -it <pod_name> -- /bin/bash
3. Curl the URL specified for the Ingress service. If the URL is not accessible, check for a firewall issue between the cluster and the external endpoint.

curl <host_name>.<domain>
Why does the location subdomain not route traffic to control plane hosts? 

 What’s happening 

After you assign hosts to your Satellite location control plane, you see a message similar to the following.

R0036 The location subdomains are not correctly routing traffic to your control plane hosts. Verify that the location subdomains are registered with the correct IP addresses for your control plane hosts with the 'ibmcloud sat location dns' commands.

 Why it’s happening 

The Satellite location control plane is inaccessible through the location subdomains due to one of the following reasons:



* The hosts are behind a firewall that blocks traffic within the location.
* The DNS resolver for one or more hosts is not properly resolving the registered DNS endpoints.



 How to fix it 

Follow these steps to resolve your issue



1. Review the location subdomains and check the Records for the IP addresses of the hosts that are registered in the DNS for the subdomain.

ibmcloud sat location dns ls --location <location_name_or_ID>
2. For every host in your location, complete the following steps to log in to the host and check the DNS resolution.



1. Log in to the host machine.



* If the host is not assigned to the Satellite location control plane or a cluster, you can SSH into the host machine.
* If the host is assigned to the Satellite location control plane or a cluster:



1. [Remove the host from your Satellite location](https://cloud.ibm.com/docs/satellite?topic=satellite-host-remove).
2. Reload the operating system of the host or reboot the instance.
3. [Attach the host](https://cloud.ibm.com/docs/satellite?topic=satellite-attach-hosts) back to your Satellite location, but do not assign it. Later, after you complete these troubleshooting steps, you can [re-assign the host](https://cloud.ibm.com/docs/satellite?topic=satellite-assigning-hostshost-assign-manual) back to your Satellite location control plane or cluster.
4.
Debugging storage 

Complete the following steps to debug your Satellite storage configurations.



 Log in to your cluster 



1. Log in to the IBM Cloud CLI.
