Issue/Introduction

During a Reprotect operation in VMware Site Recovery Manager (SRM), the workflow fails during the "Synchronize Storage" phase.

Symptoms:

  • SRM UI displays error: Failed to sync data on replica consistency group '<CG_NAME>'. The 'Sync Once' operation failed. Please retry the workflow.

  • vmware-dr.log contains: dr.storageProvider.fault.StorageDeviceGroupSyncFailed.

  • HPE Storage Replication Adapter (SRA) logs show a 400 Bad Request with the following specific error: HPESRA: Failed to synchronize remotecopygroup <CG_NAME> even after retries and received error Error: Group <CG_NAME>'s target <TARGET_ID> is already involved in a synchronization.

Environment

VMware Live Site Recovery 9.x

Cause

  • The issue is caused by a synchronization conflict on the HPE storage array.
  • This occurs when SRM initiates a "Sync Once" command while a manual or scheduled synchronization task for the same Remote Copy Group (RCG) is already in progress on the array.
  • The HPE SRA does not allow concurrent synchronization tasks for the same target and rejects the SRM request with a 400 Bad Request
  • SRA logs shows
    .
    [2026-02-24 13:08:25.478 UTC] [INFO] HPESRA: Put response status is :: 400 Bad Request
    [2026-02-24 13:08:25.480 UTC] [INFO] HPESRA: Failed to synchronize remotecopygroup DR_xxxxxxx_xxRD even after retries and received error Error: Group DR_xxxxxx_xxRD's target ITxxxxxxSA001 is already involved in a synchronization

Resolution

This is typically a transient condition. Follow these steps to resolve:

  1. Monitor Array Status: Log into the HPE Storage Management Console (SSMC) or CLI.

  2. Verify RCG State: Ensure the Remote Copy Group (RCG) mentioned in the error is in a Synced or Consistent state.

  3. Check for Active Tasks: Confirm that no manual synchronization or maintenance tasks are actively running on the array for this RCG.

  4. Retry Reprotect: Once the array reports the RCG is idle and healthy, return to the SRM UI and click Retry on the failed Reprotect task. The workflow will resume from the last successful checkpoint.
