Issue/Introduction

Failback plan fails from recovery SDDC to protected side with one or more VM failing to successfully restore.

 

Environment

VMware Live Cyber Recovery 7.27.x

VMware Live Cyber Recovery 7.26.x

Cause

This may happen if a snapshot task is running at the same time the failover is initiated. A new snapshot ID is updated and conflicts with the failover task. This is a race between failover and Protection Group snapshot creation. The VM snapshot are discarded because the Protection Group snapshot could not be created (due to schedule disabled during failover) and the latest VM snapshot is discarded.

 

Resolution

This issue is expected to be fixed in VLCR version 7.28.x. 

Starting with version 7.27.x, the following enhancements are available for more visibility into the restore tasks.

a. If a VM falls back to a full restore, there will be an event raised for it in the event tab in the UI. It will also have some information about why the VM fell back to full restore.

b. The percentage progress bar in the restore task will help keep a check on the progress. 

Workaround:

As a workaround, please disable the schedules of PGs manually before starting a DR operation.
