ECS: OBS: Symptom ID 12024 - Geo test connection failed

This alert is sent in the following cases:

Case 1: Single VDC switch to HTTPS case

• Upgraded the system to 4.3
• User tries to test the connection to see if it can switch Geo connection to HTTPS, but encounters an error.

Case 2: Multiple VDCs switch to HTTPS case

• Upgraded the system to 4.3
• User has uploaded Geo TLS CA and Certificates for all the VDCs following the admin guide.
• User tries to test the connection to see if it can switch Geo connection to HTTPS, but encounters an error.

Case 3: Single or multiple VDC's fallback to HTTP case

• Upgraded the system to 4.3 and has successfully switch the Geo connections to HTTPS.
• For some emergency case, the user wants to fallback Geo connection to HTTP.
• Customer uses provided API to start Geo receiver HTTP server.
• User tries to test HTTP connection to see if it can fallback Geo connection to HTTP, but encounters an error.

For case 1 and 2, switch to the HTTPS case. Use the below API to check again if the test connection is good or not.

// SSH to one node of the cluster
cluster_ip=localhost

// Get authentication token of management API
auth_token=$(curl -s -k -I -u root:ChangeMe https://${cluster_ip}:4443/login | grep X-SDS-AUTH-TOKEN | awk '{print $NF}')

// For switch to HTTPS case, use testConnection API. 
curl -kv -X 'GET'   'https://localhost:4443/rest/v1/geoConnection/testConnection'   -H 'accept: application/json'   -H 'X-SDS-AUTH-TOKEN: '${auth_token}

If it returns 200, the test connection is good. Otherwise, it returns an error message like the following (the error message might be different):

For case 3, fall back to the HTTPS case. Use the below API to check if the test HTTP connection is good or not.

// SSH to one node of the cluster
cluster_ip=localhost

// Get authentication token of management API
auth_token=$(curl -s -k -I -u root:ChangeMe https://${cluster_ip}:4443/login | grep X-SDS-AUTH-TOKEN | awk '{print $NF}')

// For fallback to HTTP case, use testHttpConnection API. 
curl -kv -X 'GET' 'https://localhost:4443/rest/v1/geoConnection/testHttpConnection' -H 'accept: application/json' -H 'X-SDS-AUTH-TOKEN: '${auth_token}
