PowerProtect Data Manager 19.11 File System User Guide

Installation and operation

You might encounter the following issues while installing or operating the File System agent.

Agent registration

On Windows, if the agent fails to establish a connection with the PowerProtect Data Manager server, agent registration might fail with the following error message:

During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping. 

1.	If the ping command is blocked in the environment, the agent registration can still complete successfully. 
Review the agent service logs at INSTALL_DIR\DPSAPPS\AgentService\logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.
2.	If the ping command is not blocked in the environment, the agent registration might not complete successfully because a network connection cannot be started. If this occurs, complete the following steps to troubleshoot the issue:

On Linux or AIX, if the agent fails to establish a connection with the PowerProtect Data Manager server, agent registration might fail with the following error message:

During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping and curl. 

1.	If the ping command is blocked in the environment and curl is not installed, the agent registration can still complete successfully. 
Review the agent service logs at /opt/dpsapps/agentsvc/logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.
2.	If the ping command is not blocked in the environment, the agent registration might not complete successfully because a network connection cannot be started. If this occurs, complete the following steps to troubleshoot the issue:

If agent registration fails with these error messages, complete the following operation:

  1. Use any network packet tracing tool to trace the packets from the agent system to PowerProtect Data Manager.
  2. Start the packet tracing between the source IP of the agent system and the destination IP of PowerProtect Data Manager.
  3. Start the network traffic between the agent system and PowerProtect Data Manager.

    Wait 10 to 15 seconds.

  4. Analyze the captured packets.
  5. Look for SYN and SYN_ACK packets to see if a 3-way handshake is being performed.

    Determine whether the source agent or the destination PowerProtect Data Manager is blocking the connection.

    If network traffic is blocked, contact your network security team to resolve the port communication issue.

PowerProtect agent service operations

To troubleshoot PowerProtect agent service operations, you can check the PowerProtect agent service log file OpAgentSvc-<timestamp>.log, which is created in <agent_service_installation_location>\logs on Windows and <agent_service_installation_location>/logs on AIX or Linux. To modify the log level and retention of temporary files, you can modify specific parameter settings in the config.yml file.

To modify the log level and retention of temporary files, you can perform the following steps:

  1. Stop the agent service.
  2. Open the config.yml file in an editor.
  3. Modify the log-level settings in the following parameters, as required:
    • DEBUG
    • INFO
    • WARNING
    • ERROR
    • CRITICAL
    NOTE These parameters are listed in order of decreasing number of messages in the debug information output. The default log-level is INFO.
  4. To retain the temporary files, set the keepTempFiles parameter to True in the config.yml file.
    NOTE The agent service and application agent communicate through the temporary files, which are typically deleted after use but can be useful for troubleshooting purposes. Do not leave the keepTempFiles parameter set to True permanently, or the temporary files can use excessive space on the file system.
  5. Start the agent service.

PowerProtect Data Manager UI display of localhost.localdomain hostname

In the PowerProtect Data Manager UI, the Application Agents, Asset Sources, and Protection Jobs windows might list the asset primary hostname as localhost.localdomain instead of the expected FQDN.

The display of localhost.localdomain as the hostname in the PowerProtect Data Manager UI windows might occur when you specify the host's actual FQDN setting for the loopback address in the /etc/hosts file. For example, when you add the following settings in the /etc/hosts file, the first setting value, localhost.localdomain, appears as the hostname in the PowerProtect Data Manager UI windows, instead of the actual FQDN:

127.0.0.1 localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 blrv027d233.blr.lab.emc.com blrv027d233

Ensure that the host's actual FQDN is not specified for the loopback address and do not specify hostnames that start with "local" in the /etc/hosts file.
