Products

• VMware HCX

Issue/Introduction

• You are migrating a Linux virtual machine using VMware HCX OS Assisted Migration (OSAM) and the migration with the error: "SDR Error (Incorrect replica storage mapping provided)" .
• The following error message is observed in the HCX user interface or within the /common/logs/admin/app.log
  

  [OsAssistedReplicationService_SvcThread-7047, Ent: HybridityAdmin, , TxId: ######] ERROR c.v.v.h.s.o.jobs.SyncCycleManagerJob- [transferId:'######' sid:'######' jobId:'######' hostname:'######'] SDR Error (Incorrect replica storage mapping provided)

• Additionally, the following error is observed in the source VM sentinel logs:
  

  ERROR [main] c.v.h.S.L.LinuxSystemConfig - AUTO not yet supported for attributes

Environment

VMware HCX

Cause

The source Linux virtual machine contains an "auto" file-system type configuration in the fstab. The "auto" file-system type is not supported by the HCX OS Assisted Migration service, which causes the replica storage mapping failure.

Resolution

To resolve this issue, unmount the unsupported file-system and restart the sentinel service on the source virtual machine.

1. Unmount the disk utilizing the "auto" or unsupported file-system type.
2. Restart the sentinel service on the source virtual machine using the following command: "systemctl restart vmware-hcx-osam-sentinel.service"
3. Verify that the sentinel configuration is no longer reporting "fsType":"AUTO" in the sentinel configuration file located at /opt/vmware/hcx/osam/etc/sentinel.json.
4. Restart the OSAM migration.
