Symptoms

Your DPA agent installs successfully but the agent is not showing in the DPA GUI. Checking the dpaagent.log file you see the following: ERR 27665.27665 20170829:153123 agent.config - registerAgentProcess(): Error in HTTP response: Unauthorized request FTL 27665.27665 20170829:153123 agent.config - initAgentConfig(): Registration was explicitly denied by the server - shutting down INFO 27665.27665 20170829:153123 agent.main - main(): Agent stopped

Cause

An optional enhancement to DPA , allows a password to be set for agent registration with the application server.If this is set on the application server then all agents must have this password set on them to register.This password is causing the agent registration to be rejected by the application. 

Resolution

To resolve this issue you will have to set the password on the agent to match the agent password set on the application server. If you do not know the agent password that is set on the DPA application, then you will have to do step 1 on the DPA Application and step 2 on all the agents.If you know the agent password that is set on the DPA application, then skip on to step 2 to set the agent password.Step 1Set an agent registration password on the application by running the following command, as administrator or as root, from dpa_install_directory/services/bin: dpa app agentpwdEnter the password when prompted and also confirm it when prompted.Restart the DPA application service.Continue to Step 2 to reset the password for all the agents.Step 2On the agent server, as administrator or as root, run the following command from dpa_install_directory/agent/bin: dpaagent --set-credentialsEnter the password set on the application server.Restart the agent services.Please contact Dell EMC Technical Support for further details or information.
