Article Applicability
The hotfix patch on this article is only intended for use with Veeam Disaster Recovery Orchestrator 5.0.0.2768.

Challenge

When executing a Replica plan, Veeam Disaster Recovery Orchestrator may hang as it processes each VM in the plan. This hang will occur if two vCenters are used (one Production and one DR), and the source vCenter is down or otherwise unreachable.

This issue only affects Replica plans.

 

The following Orchestration plans are not affected:

As this issue only affects Replica plans, the patch on this article is optional for Veeam Disaster Recovery Orchestrator deployments not using Replica plans.

Cause
