Study Notes

Prerequisites

  • Ensure the workload domain is in a stable state, with no active VMs or services running.
  • Verify that resources (storage, networking) are not used by other infrastructure components.
  • Ensure the workload domain is not subject to planned or in-flight maintenance.
  • Identify the workload domain by name and location within the vCloud Director infrastructure.

Procedure for Removing a Workload Domain

  • Preparation:

    • Create a backup of configuration files (vCenter Server and vCloud Director objects) related to the workload domain.
    • Stop all VMs and services within the workload domain.
    • Verify the domain's dependencies (interconnectivity/shared resources with other domains).
    • Assess the potential impact on other domains/services consuming resources from the workload domain.

  • Removal Procedure:

    • Use the vCloud API or vCloud Director management interface for the removal process.
    • Carefully confirm and execute the removal command.
    • Follow prompts and confirmation steps presented by the system's GUI. Avoid removal errors.
    • Allow sufficient time for complete detachment; removal often involves multiple stages.

Important Considerations

  • Data Migration: Plan proper data migration if data needs to be salvaged before removing the domain.
  • Resource Dependencies: Address all dependencies before removal to prevent errors/service disruptions.
  • Testing: Thoroughly test the removal process in a non-production environment.
  • Documentation: Maintain detailed records of the removal process (dates, times, changes).
  • Rollback Plan: Create a clear rollback plan with an alternate storage location/replica, in case issues arise.

Post-Removal Validation Steps

  • Verify complete removal and inaccessibility via VCF tools.
  • Clean up unused VMs/orphaned infrastructure objects.
  • Re-evaluate network configurations (firewall rules/connectivity).

Important Considerations

  • Security: Be aware of security risks. Ensure access controls and procedures are followed. Verify the user has the necessary permissions. Reinforce security mechanisms based on industry best practices.
  • Potential Issues and Troubleshooting: Monitor for and promptly address error messages; review error logs for troubleshooting clues. Utilize vCenter Server health checks for diagnostics. Revert to backup if necessary.

Best Practices

  • Backup the workload domain configuration before removal.
  • Outline a detailed removal plan considering dependencies and potential issues.
  • Inform all involved parties about the process and implications.

Backup and Restore Strategy

  • Establish a robust backup strategy for workload domain data.
  • Confirm backup storage availability.
  • Create a comprehensive restore plan for potential failures/issues.
