Issue/Introduction

While attempting to add an Array Pair in vLSR, the request appears to complete successfully with 0 warnings or errors but the array pair does not populate in the Array Pairs UI.

Environment

VMware Live Site Recovery

Cause

Array based replication requires a Storage Replication Adapter (SRA) to facilitate the communication and configuration between vLSR and the storage arrays.  Adding Array Pairs leverages the discoverArrays SRA command to discover and populate the arrays that have a replication relationship so as to allow vLSR to then incorporate the replicated LUNs when configuring Protection Groups, Recovery Plans, etc.

One reason vLSR may not display a warning or alert or populate the Array Pairs UI after completing the Add Array Pairs wizard is if the Storage Replication Adapter returns an empty reply to the discoverArrays request.

  • As per vmware-dr.log or SRA specific log: discoverArrays request is sent:
    • [02/04/2026 22:51:14,PureSRA.cs:ParseCommand,V] Received input: <?xml version="1.0" encoding="UTF-8"?>

  • SRA discoverArrays response returns an empty reply versus a warning or alert:
    • [02/04/2026 22:51:22,DiscoverArrays.cs:WriteResponseDetails,V] Exiting
      Setting output: <?xml version="1.0" encoding="utf-8"?>
      <Response xmlns="http://www.vmware.com/srm/sra/v2" xmlns:purestorage="http://www.purestorage.com/sra">
        <Arrays />
      </Response>

Notice no specific information about the paired arrays is returned by discoverArrays between the "Response" tags.

Resolution

  • Ensure the Storage Replication Adapter (SRA) is compatible with the installed version of vLSR.  Ensure the paired array model and firmware are compatible as well.
  • Consider upgrading the Storage Replication Adapter (SRA) to the latest supported version compatible with the installed version of vLSR and arrays in use.
  • Customer may consider engaging the Storage Replication Adapter (SRA) vendor to determine why the discoverArrays command is returning an empty response.
