ONTAP Tools for VMware vSphere 10.x / SRA Error: No SnapMirror Relationship Found During SRM Device Discovery or Failover

Applies to

• ONTAP Tools for VMware vSphere 10.x (OTV 10.x)
• Storage Replication Adapter (SRA) 10.x
• ONTAP 9.15.1P7 (and earlier 9.15.x)
• VMware Site Recovery Manager (SRM)
• AFF and FAS systems with SnapMirror relationships

Issue

After upgrading to ONTAP Tools for VMware vSphere 10.4 and SRA 10.4, Site Recovery Manager (SRM) device discovery and/or test failover operations fail with the following error:

No SnapMirror relationship found. Ensure that at least one SAN or NAS device is mirrored, and the source and destination are on different storage arrays. SRA does not support SnapMirror relationships on a single storage array.

Additional log output may include:

• SRA command ‘discoverDevices’ failed.
• SRA command ‘testFailoverStart’ failed for device …
• OTV/SRA logs show missing SnapMirror relationships in the REST API response, e.g:

{
  "num_records": 4,
  "records": [
    ... // Only some relationships are listed, others missing
  ]
}

• ONTAP CLI snapmirror show displays all relationships, but REST API call to /api/snapmirror/relationships?... returns incomplete data (missing some relationships, especially sync type).
