Base Command Manager installation, configuration, and HA verification: Quick Reference — Control Plane Installation and Configuration (NVIDIA-Certified Professional: AI Infrastructure)

Base Command Manager Installation, Configuration, and HA Verification — Quick Reference

This quick reference provides essential facts and steps for installing, configuring, and verifying High Availability (HA) of the NVIDIA Base Command Manager, a critical component in AI infrastructure control plane management.

1. Base Command Manager Installation

• Prerequisites: Ensure supported OS (e.g., RHEL/CentOS 8+), Docker installed, and network connectivity to cluster nodes.
• Installation Method: Use NVIDIA-provided installation scripts or RPM packages for Base Command Manager.
• Key Components Installed: Command Manager server, database backend, and API services.
• Post-installation: Verify service status with systemctl status base-command.

2. Configuration Essentials

• Configuration File Location: /etc/base-command/config.yaml or equivalent.
• Key Parameters:
  • Database connection strings
  • API endpoints and ports
  • Authentication and authorization settings
  • Logging levels and paths
• Networking: Configure firewall rules to allow inbound traffic on required ports (default 9443 for HTTPS API).
• Cluster Integration: Define cluster nodes and roles in configuration for orchestration.

3. High Availability (HA) Verification

• HA Architecture: Typically involves active-passive or active-active Command Manager instances with shared database backend.
• Verification Steps:
  1. Check status of all Command Manager instances using systemctl status base-command or equivalent.
  2. Test failover by simulating failure on active node and confirm standby takes over seamlessly.
  3. Verify database connectivity and replication status if applicable.
  4. Review logs for errors or warnings related to HA components.
• Monitoring: Use NVIDIA monitoring tools or standard system monitoring to track uptime and failover events.

4. Key Commands Summary

• systemctl start|stop|restart base-command — Manage Command Manager service
• journalctl -u base-command -f — Real-time log monitoring
• base-command-cli status — Check Command Manager health and HA status
• ping HA VIP or load balancer — Verify network accessibility of HA endpoint

5. Best Practices

• Always back up configuration files before changes.
• Test HA failover in a controlled environment before production deployment.
• Keep software versions consistent across HA nodes.
• Document all configuration changes and HA test results.
