Highlights CV SRA agent failures, which are system problems that prevent the CV SRA agent from starting, installing, or operating properly, and often require troubleshooting to restore normal function.

CV SRA agent failures are system problems that prevent the CV SRA agent from starting, installing, or operating properly, and often require targeted troubleshooting to restore normal function.

  • Can result from hardware faults, configuration errors, or connectivity issues.

  • Disrupt essential operations and typically trigger error messages or log alerts.

  • Often require targeted troubleshooting to restore normal function.

CV SRA agent failure causes and impact

CV SRA agent failures can occur due to a variety of underlying issues and typically require troubleshooting to resolve.

Examples of CV SRA agent failures

  • The CV SRA agent goes down after a power outage and fails to restart.

  • The CV SRA agent cannot be installed because IOx status cannot be verified.

  • “Failed to install CV SRA agent. Device is unreachable” error appears during installation.

Causes and consequences of CV SRA agent SD card failures

A power outage can cause the SD card used by the CV SRA agent to become faulty or switch automatically to “read-only mode.”

When this happens:

  • The SD card develops a fault that prevents normal device operations.

  • The SD card’s file system changes to read-only, blocking necessary writes and agent activities.

If either issue occurs, manual intervention is required to repair or replace the SD card. Automatic recovery is not possible.

Diagnose and fix CV SRA agent installation failures due to IOx issues

Diagnose and resolve CV SRA agent installation failures related to IOx configuration or service status.

Installation errors such as “Installation of the CV SRA agent failed due to inability to verify IOx status” often occur when IOx services are down, application management is not enabled, or the device appears “down” in IoTOD.

Before you begin

Gather device details and ensure you have access to Application Manager and device event logs.

Procedure

  1. Verify event logs and confirm that “application management is enabled.”

  2. Check IOx status.

    • For externally managed devices:

      • Go to Application Manager > Devices > Device > Summary.

      • If IOx is down, review “View Details” and event logs.

      • Use “Refresh IOx” and retry installation.

      • Or, run 
        show IOx
        from Application Manager > Devices > Troubleshooting > IOS Show Commands.

  3. If the device appears “down” in IoTOD, perform the following checks.

    • Confirm IOx is enabled.

    • Ensure the IOx interface is active ( 
      no shut
      ):

      • Check the g2 interface for IR809

      • Check the g5 interface for IR829

    • Validate NAT configuration with 
      show run | sec IOx
      .
    • Run 
      show IOx
      to confirm IOx services are running.

    • Download the tech support bundle (if available) and analyze CAF logs.

  4. For externally managed IE3000 devices, verify configuration.

    • Verify that the CLI configuration matches the CV SRA workflow configuration.

    • Ensure all management VLAN settings (VLAN ID, IP address, subnet, DNS, and gateway) are correct.

The CV SRA agent installs successfully once IOx services and configurations are corrected.

What to do next

Monitor event logs to confirm the installation and health of the agent.
