Error: Unable to find a matching device at the local site for the remote device in Site Recovery Manager

Products

• VMware Site Recovery Manager

Issue/Introduction

Symptoms:

• In VMware Live Site Recovery, the Discover Devices operation fails for new and existing LUNs. The system reports the following error:
  
  Error: Unable to find a matching device at the local site for the remote device '####'

• This behavior persists despite verifying that LUNs are correctly mapped to ESXi hosts on both local and recovery sites, restarting SRM services, and rescanning the Storage Replication Adapter (SRA).

• SRA logs stored under /opt/vmware/support/logs/srm/SRAs in the VLSR appliance reports connection failure to vCenter server.

Environment

• Product: VMware Site Recovery Manager 9.0.2
• Storage Replication Adapter: Dell EMC SRDF Adapter (v9.2.0.1)
• Configuration: Array-based replication

Cause

The Dell SRDF SRA utilizes an advanced setting called FilterNonVmwareDevices to filter out devices that are not presented to VMware ESXi hosts. To perform this filtering, the SRA container must authenticate against the local vCenter Server.

If the vCenter credentials securely stored within the SRA container are invalid (e.g., due to a password change or credential expiration), the SRA fails to authenticate. This authentication failure causes the SRA to report an empty device list, which the SRM appliance interprets as a device mismatch during the discovery process.

Resolution

To resolve this issue, the vCenter credentials stored within the SRA container should be updated and reload the adapter.

Prerequisites:

1. Ensure root access to the SRM appliance.

2. Verify the vCenter FQDN and administrative credentials.

Steps:

1. SSH into the SRM appliance using the admin account.

2. Switch to the root user:

   sudo su

3. Navigate to the admin home directory:

   cd /home/admin/

4. Run the SRA credential script:

   ./enableAutoSSLCertGen.sh

5. When prompted, enter the FQDN of the vCenter Server and the valid administrative credentials.

6. Log in to the SRM VAMI interface.

7. Navigate to Storage Replication Adapter.

8. Click the ellipses (three dots) next to the SRA entry and select Reload.

9. Log in to the Site Recovery client and initiate a Discover Devices operation for the affected array pair.

If the issue persists engage Dell SRA vendor.

Additional Information

This behavior may also occur if the R2 devices are missing from the masking views on the storage array. If the issue persists after updating credentials, consult the storage vendor to validate the array-level configuration and ensure consistency groups are properly aligned between sites.
