Symptoms:

• Once the inventory sync is complete, when trying to upgrade a managed product from vRSLCM, the PROCEED button cannot be selected.

• Opening developer tools in your client browser with F12 and under the Network tab Gateway Time-out errors are found for POST requests to .../lcm/lcops/api/environments
• The log /var/log/nginx/error.log will contain errors similar to the below

  [error] 839#0: *169 connect() failed (111: Connection refused) while connecting to upstream, client: VC_IP, server: VC_FQDN, request: "GET /lcm/lcops/api/v2/datacenters HTTP/1.1", upstream: "http://127.0.0.1:8080/lcm/lcops/api/v2/datacenters", host: "FQDN of VC", referrer: "https://VC FQDN/lcm/lcops/environments"

• The vmware_vrlcm.log contains messages similar to

Environment

VMware vRealize Suite Lifecycle Manager 8.x

Cause

• When managing a large number of environments, vRSLCM checks if vCenter details is present.
  • If they are missing, it will populate them with the correct values.
• The default API time out is 60 seconds for this API call.

Resolution

This issue is resolved in vRealize Suite LifeCycle Manager versions 8.10.0

Workaround:

Prerequisites

• Please take simultaneous non-memory snapshots of the virtual appliance(s).
• You have access to root user and password
• You have SSH or console access to each virtual appliance.

Procedure

1. SSH / PuTTy into the vRSLCM virtual appliance.
2. Run the following command

   vim /etc/nginx/nginx.conf

3. Add the following code block ahead of the block that starts with location /lcm/lcops/api/

    location /lcm/lcops/api/environments {
     limit_req zone=mylimit burst=20 nodelay;
     proxy_pass http://vrlcm-server;
     proxy_read_timeout 10m;
     proxy_send_timeout 10m;
    }

4. Verify nginx conf with the command

   nginx -t

5. Reload the nginx service with the command

   systemctl reload nginx

6. Wait between 5-10 minutes then retry the upgrade.

Note: Increment the proxy_read_timeout and proxy_send_timeout values higher based upon the environment size and if the Time-out errors continue.
